@unborn swallow Hey VPS stands for Visual positioning system. Meaning instead of relying on the GPS to find the corresponding location in the world you would use phone camera to capture image of your location. Then that image gets sent to the point cloud which holds the information of pre-captured environment map in our case all city which looks like this:
#🤯┃augmented-reality
dawn moat
Once the image data sets have been compared it gets returned to user all this happens usually 2-3 seconds over 4g network and gives you localisation currently at 0.5 - 1 meter distance.
On average GPS accuracy at best will be around 5 meters in any direction (radius), at worst 20 meters which is not precise and reliable at all especially if you trying to place augmented reality content. And signal can bounce off as well. VPS give you that precision and whats more now your augmented reality content can actually be experienced by multiple people as it is anchored in exact position.
@unborn swallow Let me know if that makes sense 😉
I guess another question is that you might have so what is difference from ARKit or ArCore? ARKit or ARCore allow you to track the position of a device relative to a random starting position where is VPS that Scape provide gives that location an absolute position on a global reference frame
Hope this answears all

@half basin suuupse fun. Though it feels very limited with it narrow field of view and limited input system. It does feel like the first of its kind, which makes sense.
Regarding your previous question it might not seem like it has been widely adopted, but remember it’s not for consumers. With a $5000 price tag it’s for businesses so a lot of that will not be public

We have hololense and leapmotion at the school. I found myself comparing the hololense's refreshrate a lot. I'm unsure if this is common but the hololense we used had some serious performance issues. However the hand/finger gesture input system, while limited, worked well.
The leap motion felt more reasonable and the fov is improved, but i was more interested in vr headsets so i didn't play with it much.

We've been suffering through massive jittering with our app, using ARFoundation (iOS) and image tracking. We have a bunch of panels that popup around a skeleton with information on it, and reading those panels are impossible as the skeleton constantly shifts around. We assume it's because it's auto focusing (and turning it to fixed focusing doesn't actually do anything, which is a known bug apparently).
So, we've did a bit of a hack. The TrackedPoseDriver on the ARCamera is responsible for repostioning the camera, but it does so every frame and assigns the transformation directly. So, adding a lerp to this actually helps quite a bit. Of course it's still jittery in the sense it's repositioning every frame, but at least it's smooth. One thing, is that because the TrackedPoseDriver is in the packages, we had to make a custom TrackedPoseDriverCustom script and use that instead as a component on the ARCamera. It looks like this (very simple):
[DefaultExecutionOrder(-30000)]
[Serializable]
public class TrackedPoseDriverCustom : TrackedPoseDriver
{
protected override void SetLocalTransform(Vector3 newPosition, Quaternion newRotation)
{
if (trackingType == TrackingType.RotationAndPosition || trackingType == TrackingType.RotationOnly)
transform.localRotation = Quaternion.Lerp(transform.localRotation, newRotation, Time.deltaTime * 20);
if (trackingType == TrackingType.RotationAndPosition || trackingType == TrackingType.PositionOnly)
transform.localPosition = Vector3.Lerp(transform.localPosition, newPosition, Time.deltaTime * 20);
}
}
Hopefully that's helpful to anyone here.
Note that the 20 is just a hardcoded value for speed that felt good for our experience.

i develop an AR tower defense game then i build it on my phone.
on the first run it work well but when i restart the game using SceneManagement, the level loaded but the screen is black with white ARCore logo in the middle.
the weird thing is i can still play the game but the screen black no camera feed.
i tried to fix this by creating 1 new fresh scene.
i delete the Main Camera then add the ARCore Device.
i create a button to restart the scene using SceneManagement then build it to my device.
the restart method works perfectly. i can restart the scene without any problem.

hi everyone,
I am using Vuforia for AR based gameplay with unity. The problem is with devices with no gyroscope. How do I handle AR for those devices?

@sudden geyser yo umight wanna look at this page. https://library.vuforia.com/articles/Solution/vuforia-fusion-supported-devices.html
I think image tracking will work even without a gyroscope

Not really. It's written at the bottom of the page that they need to have gyroscope
And the following are the only devices supported

@hybrid perch I tried exactly that yesterday when I finally got my hands on the device, I turned default orientation to landscape left and it stopped working
vuforia just froze after launch no camer no tracking
hybrid perch
Yes @sudden geyser but that's for ground planes and model targets
Are you sure the orientation is the issue though @sick yarrow ?

Howdy, y'all! I've got a quick question that may or may not have an easy solution. I'm trying to get the WebCamTexture from the AR Camera in Vuforia. Since you can only have one thing accessing the camera at a time, I can't just make a new webcamtexture and be done with it. So, I used the script on the vuforia website to access the webcam data--however, this is only available in greyscale in the editor. I am trying to get the color information at a certain position from the AR camera feed (I know how to do this already using a regular camera feed) but am having trouble figuring out how to accomplish this. Any ideas?

Hey, I have a problem using ARFoundation (or rather ARCore, this is only on Android), when I first run my app and go to AR scene it asks for camera permission, but when I allow it, the camera remains black as if it did not refresh with the new permission. Switching between the scenes (back to menu and AR again) does not work, you have to close the app and run it again for the camera to start properly.
Do I have to manually request permission before entering the AR scene or should this work when done by ARFoundation/ARCore ?
copper socket
Hm, no. If you allow it, it should work.
And you're sure you have the AR Session and AR Session Origin prefabs, with the ARCamera as a child of the origin and assigned?
Also, if you're using LWRP, I believe there's a step you need to do for rendering a custom background?

Yes there is, unless you're on the ARFoundation 3.0.0 preview

Hi everyone. When i scale multiple objects to fit within a meter, I run my AR app and my objects float in the air and not on the ground plane. I created an empty game object and made the objets chelidren of the gameobject and then scaled that down to say .1 and still they float in the air. The first method i place everything on the ground aswell as the second method. I can scale one cube and that works fine but more than one object they float. Any Ideas what the problem. I also cant make n prefab of all the object because then I for some reason I lose my lightbake. Any ideas ?

Do you need a precise location @half basin? As far as I know PNS is not meant for outdoors use and as such lacks the tools for location services. You can probably use C# classes to get the location but it's not gonna be very precise
half basin
i tried the device on other software like Google Earth and it's own Software (U-Center) i got a good reesults, it was enough good for my project.
But when i try this script here https://docs.unity3d.com/ScriptReference/LocationService.Start.html
i get this an error message that location service is not enabled
so I think unity is not even getting Data from the device
hybrid perch
That’s correct @half basin, it specifically says that the location system is only available on mobile
half basin
But I think, it have be a way to get the data from somewhere on my PC to my app. Because when the device work from other sSoftware the data, that I need, have to be somewhere in the PC . I think for that, there is a way how to use NetworkMatch API to get them.
It have to looks like this ex below: https://portal.u-blox.com/s/question/0D52p00008HKCpQCAX/ublox7-serial-communications-com-initiation

Playing with idea to identify surroundings 🙂 https://streamable.com/orfu5
hybrid perch
Pretty cool @dawn moat! Do you have the meshes loaded and identify them based on the camera input? Or is there something else going on>
dawn moat
Pretty much... Basing it on localisation parameters returned to me.The precision of geo location is key. I am using Scape Technologies VPS ( visual positioning system) and open street map data meshes... Once localisation has taken place i.e gives me correct position in terms of lat/long allowing me to load correct chunk. Then I align the meshes based on returned heading and then just raycast out which returns the names.
hybrid perch
Cool :) We've done some tests but we struggled with the precision of the GPS, especially when you get up close
dawn moat
@hybrid perch Yeah Gps is big issue thats why I rely on VPS gives me precision of 0.5 - 1m for AR content and also returns me with 2 degree accuracy North location. Its very awesome.
Lot of things that were not possible before can now be done no more seeing object sort of in vicinity now it stays in exact location!
Now just brainstorming of good use-cases ^^
hybrid perch
Very interesting indeed! How was it to work with in Unity @dawn moat?
dawn moat
Straight forward in all honesty ARFoundation is now supported
so makes things even more easier. SDK its self is very simple in general it give you lat and long heading ect.. what you do with those params is up to you pretty much
hybrid perch
Awesome, thanks for sharing :) I'll be sure to look more into it
dawn moat
the localisation you looking around 3-4 seconds on 3g , 4g
and there is mocking capability too

hybrid perch
Deffo. Only issue I see here in Norway is the ground being covered in snow for a few months of the year. Not sure what that does with the VPS
dawn moat
It really is dependant on features around you need to localise against buildings so as long as they not covered in snow should work in theory
Here is localisation working in extreme weather.. Computer vision struggles usually with reflection, rain, lights ect...
but its been solid... You can see GPS being way off but VPS is pretty much spot on
For your case you will have little more difficulty in Norway as the service not available right now so mocking is only one way to work with it for now but you can always request availability if you got big project..
Unless you visit London 😉

Yeah I'm very jelly of you Londoners :(

If you're using LWRP, you need to create a custom background material I believe.

Hello. Is there someone here?

Filled out the application and still haven’t heard anything back from project mars. Would be nice to be apart of the growth of the tool 🥽

Hey guys!
I am currently having difficulties developing an AR application with Vuforia in Unity.
Everything works pretty much fine but I am not able for the live of me to get the 'spatial' sound to work.
I want to attach audio sources to my tracked targets so that moving/facing the phone away from the target would make the audio more quiet.
One thing I have found so far is that in my audio settings I do not have. Spatializer. But apparently that is only needed for VR projects and not Vuforia?
If someone could help me out our share their experience with that I'd greatly appreciate it!
Currently I am just decreasing and increasing volume based on the distance of the camera - but this is not at all my preferred solution. I would have thought just using a Spatal Blend 3D Audio would work, but it is either way too quiet and does not seem to get more or less quiet despite trying out different rolloffs.
tranquil light
@wooden atlas
Hey man, thanks for trying to help me out here!
Thing is I do know how to get sounds to work in general, just in this specific case it does not seem to work. This case being:
- I have a Vuforia Tracker on the floor.
- I have an audiosource on one gameobject, pretty much on top of the tracker with 3d spatial blend and rolloff etc.
- I move my phone closer or further away from the Vuforia tracker
-> Expected outcome: The source gets louder or quieter
-> Actual outcome: Sound stays the same and is way too quiet.
This seems to be pretty independant of the rolloff as well.
wooden atlas
Hmmm I was going trough some tutorials the other day and there was definitely mention that unity has the doppler effect. Im not currently at the sound part of my project yet but perhaps search for the "Doppler effect" in unity\
tranquil light
Hey! The doppler effect as far as I know it, would just "warp" the sound when moved, you are right though, I might check it out and see if that works at all, but my guess it does not.
wooden atlas
i'll quickly go through my history and see if i can find where they make reference of that. Its quite relevant to my project too
have you change your spacial blend in the audio settings from 2s to 3d?
2d*
Hey Andre so I found what I was refering to. In your audio source there is a 3d Sound settings drop down and within it that you can change the doppler settings\
but you have to change the spacial blend form 2D to 3D
tranquil light
Hey man, I did change it to 3d :)
My theory was that I might need a spatializer? Do you have one of those?
wooden atlas
Sorry Andre I still need to learn about a spatializer. lol One other thing i heard was if your audi listener is on your ar camera and your sound source on your objects.
tranquil light
That is correct, AudioListener is on the ARCamera provided by Vuforia and the sound source is on the objects :) Anything wrong about that?
Also dude no need to apologize, you are trying to help :] I appreciate that
wooden atlas
Thats how I understood it. I've change to ARfoundation to weeks ago and having alot more success with my AR. Especially with the scaling dilemma. Cool no apologies
tranquil light
You did? I tried out Arfoundation and for my usecase (Mainly printed 2d images with overlaid animations) the tracking was just awful!
it was all wobbly and shaky and I for the life of me did not get it to be stable. Vuforia on the other hand was super stable from the get go ~
wooden atlas
Vuforia's image tracking is good but ground plane detection I feel ARfoundation that uses ARcore is superior
tranquil light
That could very well be, I do not need ground plane detection though.
Also just fyi you can connect the two of them, as I found out recently in the VR configuration
wooden atlas
ah yes i saw that
The main thing for me is I have anitmations and baked lighting and you cant scale objets or objects with animation in Unity to small otherwise it wont work. Same goes for the physics in unity
Things start to go very wrong. So i needed a solution. And vuforia has one but its quite abit of coding. Whereas ARFoundation worked a charmed in this regard.

If you are just trying to get something simple up and running, I suggest using the latest released version of Unity and not an early beta. Unity 2019.2 and ARFoundation 2.1.1 is a good start. You also need ARCore support (the package is called "ARCore XR Plugin" and the latest stable release is 2.1.2). You mentioned getting camera permissions, so it sounds like you probably have that already, but make sure it's the latest verified release. If that still doesn't work, check the logcat output (cmd lineadb logcat) and see if there are any relevant-looking warnings or errors.

Heyo! So, Preview 3 of ARFoundation 3 came out recently. We're trying to get an AR-project out the door here. Need IL2CPP to be able to publish for Android, so we needed the IL2CPP-support that came with Preview 3. Great stuff.
Buuuut... the ImageTracking seems to be borked now? The ARTrackedImage instance pops into existance at the cameras position now, not the tracked image position.
Image tracking on Android with IL2CPP was fixed in 3.0.0-preview.3. However, I wouldn't recommend using a preview package for a production app. The latest stable release is 2.1. Is there something specific you need in the 3.0 preview?

Hello does anybody here know coding quite well?
lucid ember
@crystal dawn Thanks for the response. I ended up with removing the Universal Render Pipeline and was able to clear the black screen issue. I am uding the latest ARFoundation and ARCore XR Plugin. Seems to be working now.
I am having a little issue with relating to the Pose results I get from a Input.Touch.Begin event. The Vector3 for Pose.position is giving me a spot -3 on the Y and -6 on the Z. But, the point that I am looking at is a -.25 Y and -.2 Z. Basically a spot on the table infront of me.
Trying to find out why this is.
crystal dawn
Input.Touch doesn't deal in poses, so I'm not sure what you're referring to. Could you post some code?
lucid ember
Sorry for the confusion. I am using a target to indcate the position that I am looking at. Using RaycastManager I and getting a hit pose as the target for where I instanciate my GameObject.:
var screenCenter = Camera.current.ViewportToScreenPoint(new Vector3(0.5f, 0.5f)).normalized;
var hits = new List<ARRaycastHit>();
raycaster.Raycast(screenCenter, hits, TrackableType.Planes);
placementPoseIsValid = hits.Count > 0;
if (placementPoseIsValid)
{
placementPose = hits[0].pose;
var cameraForward = Camera.current.transform.forward;
var cameraBering = new Vector3(cameraForward.x, 0f, cameraForward.z).normalized;
placementPose.rotation = Quaternion.LookRotation(cameraBering);
}
From the placementPose I get the position and rotation. This is the information that I do nto clearly understand. Is +Z UP or Forward?
lucid ember
Thanks for the clarification.

Hi guys, I dunno why I cant get this to work it seems to be a simple thing to do. Can someone just check where I'm going wrong with this. I just want the sound to sart with the spawned object.
[RequireComponent(typeof(AudioSource))]
public class ARTapToPlaceObject : MonoBehaviour
{
public GameObject objectToPlace;
public GameObject IndicatorHolder;
public AudioSource Audio;
public AudioClip NatureSound;
private ARRaycastManager arOrigin;
private Pose placementPose;
private ARPlaneManager planeManager;
private bool placementPoseIsValid = false;
private GameObject spawnedObject;
void Start()
{
IndicatorHolder = GameObject.Find("IndicatorHolder");
arOrigin = FindObjectOfType<ARRaycastManager>();
Audio = GetComponent<AudioSource>();
spawnedObject = GetComponent<GameObject>();
}
// Update is called once per frame
void Update()
{
if (spawnedObject == null && placementPoseIsValid && Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
{
PlaceObject();
}
if (spawnedObject == null && placementPoseIsValid && Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
{
Audio.Play();
If you are spawning the spawnedObject in PlaceObject then the if surounding the Audio will be false and not call the play.
put the Audio.Play() in the same if clause as the PlaceObject call.
Has anyone been able to get the scaling of the ARSessionOrigin to work with two finger touch and scale with the pinching gesture?

What version of unity and render pipeline would y'all recommend for doing AR stuff for ios or android phones? I'm just diving into researching and seem like there's a lot of different suggestions/recs/etc
hybrid perch
i've been having various issues with LWRP and ARFoundations @autumn hare. So I would be hesitant about using it in production. But ARFoundation 3.0 mostly works so if you wanna get into it that's what I would recomment. Think you need 2019.1 for it at least

Hello There，I'm new to this and having 2 question. First is I would like to know how to put effects on Mask Filter.Second is I need some guide to make face deformation for my AR software (Face Morphing Filter on Snap chat).Thanks
Morph face — change face shape making it slimmer, wider, changing eye size, the shape of the nose and head proportions.

Thanks @hybrid perch - this is super helpful info

No worries. The only major issue I've had with it is image tracking, so be aware of that if you plan on using it

Hi guys, has anyone been creating instances of RuntimeReferenceImageLibrary in ARFoundation 3 preview?
In short, I want to be able to download an assetbundle of trackable images to be used at runtime with the app having no prior knowledge of them. Is it possible to do this by bundling an XR reference image library? At the moment it seems that (on Android) it still depends on the .imgdb file that the arcoreimg tool outputs, but this is written into the StreamingAssets folder. I would also require it to work on iOS too.
On the other hand I noticed an API call that can add images dynamically with a mutable reference library. I haven't tried it as of yet, but I was under the impression this might not be practical for a database with hundreds, maybe thousands of images. Is this correct?
lucid ember
@crystal dawn What Happened to the ARSessionOrigin.Scale property? I do not see it in the current ARFoundation 3.0.0-preview3
crystal dawn
@lucid ember That was removed over a year ago in a very early release. All it did was uniformly set the scale of the GameObject's transform, and it's weird to have 2 ways to do the same thing.
crystal dawn
@fair estuary All XRReferenceImageLibraries must be built into the app; they can't be downloaded later. However, as you noted, you can construct new reference image libraries at runtime.
but I was under the impression this might not be practical for a database with hundreds, maybe thousands of images. Is this correct?
I don't think that would be practical with aXRReferenceImageLibraryeither; neither ARCore nor ARKit would accept that many. It's expected to be a dozen or two, not hundreds.
lucid ember
@crystal dawn Thank you for that explanation. I have only been looking into implementing in the past few weeks. I am would really like to get into the MARS project. From what I am doing and what I want to do, MARS looks like a great solution.
My biggest point of irritation is the need to build and Run on my Androids.
fair estuary
@crystal dawn alright, thanks for clarifying that. We could actually consider just building that image library into the app as normal. I don't actually have hundreds of image targets haha, I was looking towards a worst case scenario as it is research for a production app to replace one that currently uses Vuforia's Cloud Reco for image targets. The majority of the content will be based on plane tracking now, I was just hoping for a (scalable) way of replicating the ability to use downloaded image targets
But obviously, wouldn't want to have it struggle if the size of the library grows!

Does anyone know if the ARFoundation will work on the Windows Surface Pro 4 device? Is there a Plug-in for that or could I use the Windows Mixed Reality plugin?

Hey guys, I'm new to this discord. I have made a couple of AR-applications in the past, but it's the first time that I have a problem that keeps on persisting. Would one of you guys be interested in a quick videochat to resolve the problem. It's stuck at the creation of the pipeline state. (Or do you have any advice?) Greetings, Maarten from Belgium 🤔
strange fossil
I am using Unity ARfoundation and ARKit. How can I enable feature points?
The little yellow dots that show where 3D objects are
crystal dawn
strange fossil
Thank you
crystal dawn
yw 🙂
strange fossil
Would I add this script to the camera? I’m not going to be doing anything special with them right now, I just need them to show.
@crystal dawn
I’m guessing the way this works is, the prefab that I input will be created for each and every point?
If so that’s perfect
crystal dawn
No, you must put it on the ARSessionOrigin.
strange fossil
Ok
crystal dawn
It creates one instance of your prefab for each point cloud (not each point in the point cloud). ARKit and ARCore will only ever produce exactly one point cloud.
strange fossil
Also what is the AR Point visualizer
Ok
What I’m trying to do is, take all those dots made by the points and make them never disappear
So they always stay
Is that possible?
crystal dawn
The ARPointCloudParticleVisualizer visualizes a point cloud using a particle system. The ARPointCloudMeshVisualizer visualizes a point cloud using a single mesh with MeshTopology.Points.
strange fossil
See these dots?
crystal dawn
Both visualizers will only draw the current set of feature points
crystal dawn
if you want them all to persist, you'd have to do that yourself. Each point in the point cloud has a unique id.
strange fossil
Oh I see
A point cloud is all the dots
A single point is one
To explain this better, there is a game called Scanner Sombre were you map out a cave with only these little dots
ARKit does this automatically
So if the dots never go away
As in save them
crystal dawn
What do you mean
ARKit does this automatically
strange fossil
Then you could (in theory) scan your room and have a 3D map of a room made out of dots
It’s a built in debugging feature
crystal dawn
Does what automatically?
strange fossil
Creates feature points from the camera to sort of map out it’s nearby environment
Like how the dots are making an outline of the blanked
You can hide and Unhide the dots
crystal dawn
ARFoundation uses ARKit for its backend on iOS. I'm not really sure what is being done "automatically" that is different.
strange fossil
Nothing is different
crystal dawn
So is your goal to save all the feature points over every frame?
strange fossil
Yes
Exactly
I was thinking each point could have an object attached to it on creation, that will not vanish
crystal dawn
Right, so each feature point (point in the point cloud) has a unique id. By looking at the list of feature points each frame, you can build up a map.
crystal dawn
The docs I linked above provides 3 parallel arrays: the positions, confidence values, and identifiers. You could have a map of identifier to 3d point and update it each frame from those arrays.
Would this lag out the device after too many were generated?
Depends on what you do with them. But each frame, you typically don't get a huge set of new points; it updates existing points.
strange fossil
So the identity of each point stores it’s location?
Ok
That might be a problem
Thank you for your help by the way I’m new to AR stuff and only slightly used to Unity
crystal dawn
So it's like this:
Frame 0
Identifiers [0, 1, 2, 3, 4, ...]
Positions (x0, y0, z0), (x1, y1, z1), (x2, y2, z2), ...
Frame 1
Identifiers [5, 0, 1, 7, ...]
Positions (x5, y5, z5), (x0, y0, z0), (x1, y1, z1), (x7, y7, z7), ...
and so on. Over time, if you map a room you might get a few thousand points total. It really depends on a lot of factors though.
strange fossil
Maybe a script that attaches a game object to each point when it shows up, and lets the point disappear but the game object stays
crystal dawn
If you try to create a different gameobject for each point, that isn't going to scale well.
crystal dawn
I don't think it would be hard to store a Dictionary<ulong, Vector3>, update it each frame, and visualize it using a particle system.
That should scale pretty well
strange fossil
Ok. So now I need a bit more basic help like, I make a script that does this right? I then.... attach it to a random game object in the scene so it runs?
I really need to take programming courses or something
crystal dawn
You'll have to write a bit of code to do this. We don't provide scripts that do exactly this, but you can do it using ARFoundation's API.
crystal dawn
@strange fossil if you create an "AR Default Point Cloud" and replace its point cloud visualizer with this one, I think it should do what you want.
Seemed to work pretty well even with lots of points
strange fossil
I can't thank you enough, I will try it asap!
does the AR point cloud need to be a child of the AR Session Origin?
crystal dawn
It needs to be on the same gameobject as the ARSessionOrigin
strange fossil
OK
Also it is worth mentioning that I am going off this:
and my scene is set up as:
I simply imported the code you got me and it says this:
I havn't applied it to anything yet
'NativeArray<ulong>' does not contain a definition for 'HasValue' and no accessible extension method 'HasValue' accepting a first argument of type 'NativeArray<ulong>' could be found (are you missing a using directive or an assembly reference?)
Am I missing an AR library or module?
I put it on the AR default point cloud visualizer (replaced what you said) and it still says the same thing
@crystal dawn
What does your scene look like I probably messed mine up
You still there?
crystal dawn
@strange fossil sounds like you're using an old version of ARFoundation. What version are you using?
crystal dawn
Just remove .HasValue and .Value.
crystal dawn
So like pointCloud.positions[i] instead of pointCloud.positions.Value[i]
crystal dawn
Just get rid of those checks
crystal dawn
In later versions, I made those properties nullable since they might not exist on all platforms. But they should both exist on ARKit.
strange fossil
ok
I'm removing them now
Ok. I removed those and put it in the assets folder
no errors yet
crystal dawn
In the picture you posted of "my scene is set up as:" -- you don't want the "AR Default Point Cloud" in the scene. You need to make it a prefab and assign it to the point cloud manager.
It's the same pattern as in the description for creating an AR Default Plane prefab described under the "Visualizing Trackables" section of https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@2.0/manual/index.html#basic-setup
crystal dawn
you have two session origins
your ARPointCloudManager should be on the GameObject named "AR Session Origin" (which also should have an ARSessionOrigin component on it)
crystal dawn
Now you've lost your ARSession 🙂 Just re-add it from the GameObject > XR menu
crystal dawn
And you also need to assign your Point Cloud Prefab
crystal dawn
Oh right you said that
cool
Make sure the "AR Default Point Cloud" is the one you just created, and not the one included in the samples (if that's how you started)
strange fossil
I have to borrow a family members Mac to use xcode and upload this to my phone
I think it is
it's a prefab with custom script on it
crystal dawn
If you have an Android device it will work there without any modifications
crystal dawn
Alright then I guess you'll have to hunt down that Mac
strange fossil
yeah
crystal dawn
FWIW I tried it on my Pixel 1 and it worked pretty well. I don't know how many points exactly but it looked like hundreds
strange fossil
can you post a screenshot?
I can't get the mac right now but I have a virtual mac in virtualbox
the problem is my Iphone won't passthru to the virtual machine
crystal dawn
A static screenshot just looks messy. It's more compelling when you look around and see all the points. Probably even more so if you turn off the pass through camera and just seen the points.
strange fossil
EXACTLY
thats exactly what I am doing
you have been soooo helpful
google scanner sombre and look at images
this is the goal
then I will make it google cardboard
so VR, dots
@crystal dawn you don't have a mac do you?
strange fossil
It's probably not possible for me to send you my .xcodeproj file and you send me the .ipa file it creates?
it normally sends the app to a phone plugged into it but it can also output a ipa
I'm gonna try the virtual machine again
crystal dawn
I guess it's technically feasible, but I think you should try to get ahold of a Mac or an Android device 🙂
strange fossil
yeah
I have a macbook here but it's not got any OS on it
I'm trying to make a bootable usb installer
crystal dawn
I'm going to step out for a bit. Good luck; lemme know how it goes 🙂
quaint flint
hey so I finished my game and I want test it on my phone but i need the camera to work on my phone not webcam does anybody have any solutions

@quaint flint Dont quite understand what is your question
Are you asking how to enable permissions on your phone to use camera?
strange fossil
@crystal dawn Update: I finally got a mac and I imported it into Xcode, and it went sorta smoothly. The problem is The app opens, I can see the camera but there are no feature points visible!
strange fossil
@crystal dawn you there?
crystal dawn
@strange fossil It's hard to debug your problem directly, so I can't be sure what's going on. I'll add a sample to https://github.com/Unity-Technologies/arfoundation-samples that shows how to do this.
neat grotto
Does anyone has any luck with azure spatial anchors with ios? I can't get the samples built with xcode 11. I have installed pods and everything, but there's 100 errors like this: Undefined symbol: ssc[different_function_name]

@crystal dawn thanks!
What’s the name of the sample?
I see stuff like eye laser visualizer and stuff
strange fossil
@neat grotto probably won’t fix your problem but try running the .xcodeworkspace file instead of the .xcodeproj
I just read about that
I’m having a linked command error
strange fossil
@crystal dawn It says the last commit was 8 days ago
neat grotto
@strange fossil yes, I tried to run with that workspace file. I'm somewhat familiar with those things, but couldn't get it working. In the examples they mention xcode10, but I've Xcode 11, so it might be that..
strange fossil
@crystal dawn can you help?
strange fossil
most people that come here don't end up getting help
strange fossil
@crystal dawn
crystal dawn
@strange fossil Slow down; I haven't added it yet 🙂
strange fossil
@crystal dawn are you availably right now?
crystal dawn
@strange fossil I'm currently preparing the next release of ARFoundation, which will also include some new samples in the samples repo. I'll add a sample showing how to visualize all the feature points either with or shortly after the release.
strange fossil
OK thank you
also quick question
I enabled unity vr mode and it's keeping my AR camera from moving
I tried attatching the camera to a parent object and giving the parent the tracking script
didnt work
crystal dawn
Are you trying to VR and AR at the same time?
strange fossil
@crystal dawn yes
Apparently VR disabled camera movement
And putting the camera as a child of an object doesn’t make it work
So what ends up happening is the feature points move wrongly and the dots don’t line up with the camera view
because the dots are moving around the scene but the camera is not
@crystal dawn I'm gonna try without the AR, then try and have the feature points added later.
crystal dawn
Okay, ARFoundation does not support VR, so that would not be expected to work.
strange fossil
Is there any possible way to make the AR Camera render in 3D sidebyside?
@crystal dawn
also, I know this is possible because I have an app (ARMix) that does this
crystal dawn
Side by side what?
strange fossil
it has VR(the camera moves) and you can see the dots
I mean like this
this
I need the app to render like this
It is possible
If you have time, get ARMix and see what happens when you go in VR mode
crystal dawn
Not with ARFoundation, no. It blits the camera image to the screen to provide pass through video for handheld experiences. Your screen shot looks like an entirely virtual scene rendered with careful perspective corrections and is probably meant to be placed behind a lens.
strange fossil
See
This was made in unity
It shows when you start the app
The camera doesn’t need to pass though
Only the feature points
The skybox in this scene has been replaced with a 360 panorama of a room
crystal dawn
Right, but it takes into account perspective correction for the lens (I assume Cardboard or similar)
strange fossil
yeah
crystal dawn
It can be done in Unity but that's not what ARFoundation is for.
strange fossil
I only need AR foundation for it's feature points and 6dof capabilities
not the camera
crystal dawn
I think there's a bit more to it than that 🙂 You still need to map the feature points to the screen with the correct distortion applied.
nocturne breach
Can anyone help me in 2d?
strange fossil
Nah nah I don't need distortion
that's optional
I want
screen is black
if you move phone around
feature points show up
the view is google cardboard
I've got the black screen with feature points
crystal dawn
Remind me again what isn't working? Is it the camera's position?
strange fossil
ok
when I enable VR support in unity, when the app is built and runs, objects do not move around. They stay still relative to the camera's location.
so if I walk towards a cube
it will move away from me at the same speed
this is the desired result
crystal dawn
How is your camera setup? What controls its movement?
strange fossil
XR's tracked pose driver
crystal dawn
And what is the input source?
crystal dawn
"Pose Source"
crystal dawn
Tracked Pose Driver
crystal dawn
"Color Camera" is selected?
crystal dawn
Cardboard VR is typically a 3dof experience, so that isn't surprising.
strange fossil
but it's stopping the Tracked pose driver from moving the camera
Without VR enabled: Cube will hold it's real world position(like any AR app)
crystal dawn
Sounds like two systems are fighting
crystal dawn
That's not something I've tried, so I can't say what the problem is.
strange fossil
also I tried doing what you said with the replacing the cloud Particle visualizer with the "ARMapVisualizer"
and that just makes the points invisible
but it worked for you
with the screenshot you posted
crystal dawn
Could you log a bug about the VR/AR issue? https://unity3d.com/unity/qa/bug-reporting and send me the report id
strange fossil
This is the result
Feature points, and cube
you can move towards the cube
it all works
@crystal dawn
but when I add vr is messes it all up
can't move camera
can't look around cube
crystal dawn
Great thanks. I'll take a look.
strange fossil
Do you know if you can replace the “AR Camera” with another camera and just add the same components to it? Will it still work the same?
crystal dawn
Sure; there's nothing special about it
strange fossil
I know you can remove it from being a child and just have it in the scene
Ok
What if
The stereoscopic camera was two cameras
Side by side
Could one be a parent camera and the second a child
And render side by side
And still work with AR?
crystal dawn
If your goal is to get the results of the AR camera and VR camera overlayed, no that wouldn't do it
strange fossil
Ok
Gah
It seems like an easy enough idea
Idk why it’s so hard
Results I want are this
No live camera feed
Only feature points
Black background
And then the feature points to never go away

Hey all, I’m doing some AR stuff with leap motion and I’m trying to solve a problem that I don’t really know how to solve: I’m trying to be able to grab a knob (like a volume knob in your car) and be able to twist it left/right. You can get the direction/normal of your hands at all times, and somebody suggested projecting the direction onto a plane, then getting the delta between that plane and the normals of the knob I’m grabbing in order to translate the rotation of my hand to the rotation of the knob around its local z axis
The question boils down to: how would you Project a quaternion rotation onto a plane so that can then be applied to the knob I’m grabbing?
Also yes I already tried constraining it’s rotation along the X & Y axes in the rigidbody component, but those are world axes and I can’t figure out how I’d change that to local, which is why I have to write this from scratch.
This was my attempt at constraining its rotation to Z only via the rigidbody component (the knob is tilted, so I can’t use world axes) https://gfycat.com/BronzeSaltyKrill
strange fossil
That’s really cool
I wish I could help
@crystal dawn what if I put the point cloud particle visualizer on the camera?
That way the camera could be frozen in the scene but the particles wouldn’t move away
strange fossil
How can I use arkit's 6dof functions with VR?
Can I simply attach a Tracked Pose Driver to the camera?
or the camera's parent?

That did not help
does anyone have any clue how to render an ar camera in Google Cardboard format- WITHOUT using the google cardboard built in feature?
strange fossil
@crystal dawn So what could be preventing your ARMapVisualizer script from working?
You sent the screenshot, so It worked for you.
Can you send a pic of your unity editor and setup?
cedar geyser
@atomic badge rigidbody rotation constraints are in local space so I'd start with making sure the knob itself is properly constrained. From there the problem becomes a bit simpler - the hand is applying an amount of angular velocity each frame, which can be just a float (as rotation is around a single axis).
atomic badge
@cedar geyser that’s where my problem lies, actually. If I constrain it’s rotation to the z axis only, it rotates as if the Z axis is straight upward, but when I select the object in unity the blue arrow is pointing in the direction the top of the button is facing (something like 30 or so degrees positive on the x axis)
Which means somehow somewhere unity is interpreting my object as not rotated but it’s also noting that it is rotated because that’s how it points the arrows for moving it in the scene editor

@strange fossil that shader will work with legacy/builtin renderer only
you just need to create a material from shader, then add the script to your camera and select the material in it

I think I figured it out

Anyone had an positive or negative experience from updating to iOS 13 with ARKit-based app? Wondering whether I should update or not. I'm not encouraged by bug reports with iOS 13 so far.
strange fossil
What’s wrong exactly?
I’ve updated and use ar apps, haven’t had any problems and iOS 13 is the best operating system yet.
cedar geyser
Nothing wrong, just don't want to risk updating if there's a chance it will reduce AR performance with AR Foundation. It's not clear if updating makes apps use ARKit 3 instead of 2 and what that might mean.
strange fossil
@cedar geyser Apps use ARKit on their own, iOS won't make the app use newer ARkit. That's up to the devs of whatever app. iOS 13 has worked perfectly for me and the new ARKit 3 has some awesome features!
hybrid perch
Not any trouble so far @cedar geyser. Also you get access to human segmentation which is super fun
crystal dawn
@strange fossil I added the sample which shows all point clouds over time. See https://github.com/Unity-Technologies/arfoundation-samples/tree/master/Assets/Scenes/PointCloud
strange fossil
Thank you!!
@crystal dawn can I just import the .unity files into my preexisting project?
crystal dawn
You'd need the entire directory for that sample. And your preexisting project would need to be on the same version of ARFoundation, 3.0.0-preview.4
strange fossil
So I need to create a new project and use the AR Foundation and ARKit plugin 3.0.0-preview 4 and do everything I would normally do to recreate my app, then what?
I want to keep everything as clean as possible
I think I know what to do.

I would suggest cloning the samples repo into a new directory and build it to see if it does what you want.
If you're happy with it, then the only component you need is the ARAllPointCloudPointsParticleVisualizer and you should be able to adapt it to your specific needs.
crystal dawn
Depends. You can probably safely downgrade if you're at least on 2019.2.0

Hi! Does anybody of you know, if the ios remote works? It is marked as depricated in the app store.
I use Unity 2018.4.x with ar foundation and I must build a iOS App for tablets.
https://blogs.unity3d.com/2017/08/03/introducing-the-unity-arkit-remote/
hybrid perch
I believe the remotes have been put on hold until Unity is deploying MARS @rough swallow
rough swallow
hmm ok, that could be, thank you. @hybrid perch
hybrid perch
I might be wrong, but that's the impression I have at this time
rough swallow
it's a cumbersome task, to build the app on the target device every time. But i don't know a other way to debug ar kit in the editor.
But MARS is comming with 2019.3, so i hope it comes fast 🙂
hybrid perch
Agreed. I've been building with development build checked lately, which speeds things up. Especially if you can check scripts only build as well
rough swallow
that sounds good.
dawn moat
@rough swallow I suggest catching the process of build targets so if you developing android / ios at least it saves time to switch between build targets
rough swallow
@dawn moat thanks, I work on a windows machine and the build target is ios. I build the app on windows, copy the xCode project to mac and build it to the tablet. I'm in the end of the project and play with litte variations of numbers or 3d changes, but the whole build process for just 2 second check how it look on an ipad annoys me 🙂

Need to revisit an AR app created half a year ago and wanted to update both ARFoundation and LWRP.
Without spending half a day browsing this thread
https://forum.unity.com/threads/arfoundation-v3-0.736148/
Can anyone tell me what the current (as of Oct 24, 2019) compatible and latest versions of

LWRP
are?
Thanks!

Does anyone know how to get Unity to add the Vuforia configuration asset into a new project? I've switched Platform to Android, I've enabled Vuforia AR Support in Project Settings>Player>XR settings. I know I'm supposed to get a Resources folder with VuforiaConfiguration.asset where I can put my license key but it's just not showing up and I'm so confused.
misty berry
Nevermind, I think I've sussed it.
Turns out in order to get it, you have to first try and use one of the game objects, then it'll give you the bloody resources folder with the config tool
unreal slate
@dawn moat what is your marker? Or do you place virtual objects based on GPS?
dawn moat
@unreal slate I dont use any markers. I use VPS service provided by Scape technologies. Problem with gps this would never be possible due to inprecisions. Using VPS I capture one image frame and that image gets sent to AR point cloud where features of image gets compared to surrounding data that sits on cloud and orientation and heading gets returned. In short it works like gps but with higher degree of precision and accuracy. Check it out here www.scape.io
Everything is ancored oto geo lat and long which means content will always appear in this exact location 😀
Super exciting stuff! Allowing me to have real city building occlusion! Note how car goes behind building!
I use osm data and then align world with returned north and able to occlude evey building in my area

Sounds beautiful but I am not in London and as I understand it is only available in London? Is there a way to scan/take pictures of the street myself and then use it as an input perhaps in a developer mode?
dawn moat
Not currently sadly.. There are some areas in Berlin available more cities on the way
unreal slate
I think they should allow people to scan their streets and add it to the package. They would grow their consumer base dramatically

From what I understand, they may be going through a specific pipeline. They may need to create an entire interface to allow for user entered data

Looking online and trying to find a way to just remove all planes found in an AR Foundations session. The ARSession Reset() does the job but it's very disruptive - I just want to clear away excessive planes. Anyone got something for this?

Hello everyone, i am currently building out an indoor navigation AR app for my university, and i am here to seek some council. So i know about SDK's like ARCore & ARKit, and i also found something that is called placenote that allows for some pretty swear indoor navigation. However.. Placenote is only supporting IOS, so that is ruled out in my equation. Do we have anyone here experienced with indoor AR nav, that can council me? How can i achieve this now?
glacial frost
I recommend you read about cloud anchors in arcore documentation
btw. Cloud anchors last only 24 hours
thin condor
Ye i did play around with that yesterday, the only thing i dont like about the arcore anchor cloud is that it requires a host. So i want to be able to use the anchor cloud, to save predetermined routes as maps, and whenever i select a map on my phone, all the anchor data for that map should load, not be waiting for a host etc..
But i believe the problem with the 24 hour period can be solved using firebase cloud storage. I saw a github and get started page for that
glacial frost
Do you use augmented images in your project to specify the position of the device in space?
@thin condor
thin condor
So i have not come to that stage yet. I have simply built out my app that will be connected with the AR now. That is one thing i am uncertain about how i will get it to work. I need something to track the virtual image (an arrow) in real world space, so whenever i get to that real world space, the virtual image will appear. I do not know how to do that.
I will have a determined route map for every destination i will allow in my app, so whenever i choose a destionation, information with all the nodes in AR will be loaded for that route, if that make sense?
glacial frost
I found an interesting approach on SO, which I intend to use in the current project. https://stackoverflow.com/questions/51026662/is-it-possible-to-develop-indoor-navigation-by-using-arcore
second post
thin condor
hmm gotcha, thanks
Damn, that will be a very unconvinient way for indoor navigation, and i can not assure that placed out "waypoints (like images)" will be there.
I need something that can differentiate postitions in real world to virtual world
glacial frost
In that case, only cloud anchors come to my mind
thin condor
Yep i agree. Must be a way to distract that feature out of the cloud anchor system, without hosting and all that
glacial frost
you could place simple qr codes
Well, unless the university authorities do not allow it
thin condor
mhm ye
I found this example: https://www.youtube.com/watch?v=Gf-Qu29RLUo So when he is creating a sphere, it takes a (x,y,z) position. But that position seems only relative to the camera unfortunately
Oh, that's from ARKit toh: https://gyazo.com/7dc5e349a2512f84dc6085b564aff336
thin condor
ye im so tilted by that xd
Ye if i could use placenote, i would been on a good way
COME ON GOOGLE
glacial frost
I have the impression that Google deals with a lot of less important things when it comes to ar
thin condor
Yep i agree. More like dummy content than real world solutions. Indoor nav for example
I honestly dont like how ARKit keeps it bound to a specific architecture like IOS. ARCore works atleast for both IOS and Android
I will just have to go with ARCore anchor
glacial frost
Good luck, I still don't know how to configure it correctly in my project
thin condor
Thanks! What's your project about?
glacial frost
and the documentation for unity is much worse than that for native android
Scanning planes and drawing a map of rooms
thin condor
Oh cool 👍 I got the unity version with ARCore to get up and running with their sample app atleast
But that is nothing done from my side that is 😛
glacial frost
Is it possible to delete all trackables in the current session without having to reset the session (delete and add ARCoreSession object again)?
thin condor
I believe that works yes
thin condor
Delete all trackables in the current session
Check the ARCore documentation about trackables and ARSession. I believe something was in there if i remember
glacial frost
I can't find it, if you know something, please give an example
sacred idol
I don't think there is a way @glacial frost
I mean, you can delete manually using Destroy but they recommend against it in the docs
I had to end up resetting as well, wich came with its own set of problems
(I am using ARFoundation/ARKit tho)
glacial frost
destroying trackables doesnt work
glacial frost
you can hide them/stop rendering but thats all
sacred idol
I struggled with the same
glacial frost
but it really sucks .when it resets sessions all vertices of the detected planes become useless
sacred idol
tell me about it, if you are doing object tracking you risk a Crash if you reset while looking at an object sometimes
I am not sure it is on Unity's hands, maybe internally ARkit/Core are like that
glacial frost
I am worried that arcore developers have not added the basic functions and using opencv along with this is tragic
sacred idol
or it would have been a no-brainer to put a "delete"
sacred idol
to be honest, even image tracking is a bit shitty compared with tech from 5 years ago that even works in all phones (vuforia etc)
so yeah, exciting about merging it all but still not done
glacial frost
I think it would be better to stay in VR for now and come back in a while
ok, I think that's enough complaining, gotta go back to the project xD

Greetings,
I'm not very familiar with vuforia and AR.For that reason i have some issues.
- how can i make the app to recognise(dynamically) a text in a picture and turn it into a TTS?
2.I have some pages with speech balloons and i want to show a button above it so the user can press from his/her screen(Not irl).How can i do that?
wide steeple
@outer pewter for text recognition you'd need to use something like Tesseract
for 2. easiest would be snapping GVR plugin into the project and then using GvrReticlePointer - see how its done in HelloVR sample
outer pewter
@wide steeple 1. Is it really necesary the tesseract for the text recognition? Isnt the camera from the phone enough?
- I see VR instead of AR. will they be okay for my AR project?
wide steeple
🙂 Tesseract not as in Marvel lol
re 2 - yeah should work, i.e. you can switch to 2d mode and still have the reticle pointer
the pointer also works with screen tap out of the box, which is what you need

Currently you can't. But Unity are working on a new thing called MARS which will include a remote app to do live debugging. It's a bit of a hassle at the moment

I'm using ARFoundation, basing my work on the samples. I see the sample 'planes' that are detected are always convex, does anyone know if that is a limitation, or just an issue with the samples?
I would love concave shapes but It's not clear if that's a limitation or just a bug

When spawning an object that ought to be on a plane, is it best to spawn that object in world space or parented to the plane it's being spawned on? It seems planes can move / rotate.
glossy abyss
Im having problems with stable image tracking in AR Foundation for iOS. I notice that when I have tracked the image the object spawns and stays perfect in position as long as I keep the tracker out of the camera view. When the image is in the view it looks like it constantly tries to RE-track the image which causes my model to jump around. Is there a way to stop the RE-tracking process?
hybrid perch
Which ARFoundations version are you on @glossy abyss?
hybrid perch
I haven't had good results with image tracking with v3 yet. I'm still on v2

tried to move back to v2 but that caused a lot of error for me with all the other packages
hybrid perch
The issues I had were different than the ones you describe though. More like it tracked the image but always spawned at 0,0,0 rotation
glossy abyss
I think its just something in the code that can be added or changed
hybrid perch
You need all the packages to be v2
glossy abyss
yes I have fixed that problem
hybrid perch
But maybe. I havent tried

with the rotation

your model should be positioned this way (look at the axis on the right top corner).

It's not so simple. Especially not with how often you get new updates to arfoundation

small lance
anyone know the best way to geolocate objects for AR? I don't need it for large scale GPS stuff but for localized positioning in a single building, need something reliable
small lance
the positioning can't be based on the planes made by the phone, though, the object has to be partially visible when the phone's not looking directly at it
hybrid perch
How precise does it need to be @small lance? We've used an asset store plugin called AR + GPS Location, which does what it says, but it's only accurate down to a few meters
small lance
Yeah, it's gotta be pretty precise, a few meters is too much error
I saw that plugin too, also tried writing my own solution using location services, but was wondering if anyone had done anything like this / if there's a way that doesn't involve GPS
there might be a much simpler solution to this problem -- like I can potentially capture the location the object should be manually on the device, but then it has to persist when I look away or can only partially see the (very large) object, etc
(I'm a noob to this so maybe that just involves saving generated plane data or something?)
hybrid perch
If you need something more precise the options you have is 1: waiting for 5G GPS which is way more precise or 2: Visual Positioning Systems like the one from Google which locates you based on what the camera sees around you
We recently developed an app where this was a question early in development. We ended up using markers to ground the objects to a physical location, but detaching the objects from the marker after they're spawned. This means they will be instatiated in the right position, but once that's done they are treated like a regular world placed object, which means you don't need the marker to be in view, and like you need only parts of the object can be visible
For an earlier research project we were placing buildings in AR based on GPS, and we used the plugin I mentioned for that. But to correct for the inaccurate GPS we also added some controls to 'nudge' the building in different directions so you could manually get the position exact

I am doing a math AR app for mobile, i have 3 cards for example 6,7 and a + sign, what's the best way to find if + if placed on the middle of 6 and 7?
distant condor
So im pretty new to unity, and i have created Canvas and added Viewport-> content-> EntryContainer-> EntryTemplate. In my c# script i am cloning those EntryTemplates using Instantiate and filling them with data (currently static later on i will try to get data from sqlite database). It will be a list of news with pictures, and a user has to select 2 of them to compare them with some external algorithms i will use
As you can see on upper image i uploaded here, i have toggle in my entry template, and i don't know how to seperate them by id or something so i know which two news have user selected
i have added function to OnValueChanged, which only gives me the value (false,true) of an instance of the Toggle object, but i need something like Toggle.InstanceID
Any idea how to know exactly which Toggle has been ToggledON/OFF ?
astral cloak
you can save the instance in a variable and then change the TAG
distant condor
when i create those toggles, can i assign them a name or a tag ?
with index, so later i can acces them and check if they are toggled on ?
astral cloak
yup just create a game object variable then gO = instance(....)
after that you can change almost anything in the gO
after that if think game object is to generic change the variable to a Toggle instead of GameObject
distant condor
i can't seem to assign a tag value to a toggle object, it says Tag: value is not defined.

We're developing a markerless vuforia app, we have a ground plane object, then we spawn an animation prefab and parent it to the ground plane. For some reason, even though the ground plane is stable in tracking, the animation keeps "vibrating"/jittering in movement.

hi guys, im building an ar app and have some trouble with coding. someone here who could help me with 2 lines of code? i want to do a quiz with 3 toggles. if the first two are activated there should appear a continue button, if the third one gets selected, there should appear a quit button. do someone know how to code that?
drowsy solar
@hybrid perch I've noted it on several newer model iPhones, so I assume it's my project or configuration introducing the latency. I'm using URP.
tawdry pivot
@drowsy solar did you happen to do any CPU/GPU profiling on device to see if something is causing the display to lag? Render/CPU heavy projects will definitely have an effect on camera rendering for AR projects.
drowsy solar
I'll double check that! This happens on non-development builds, built as release for phone. But It's possible I have something debugging related.
I was kind of worried about all the "detection" behaviours causing the lag, like having too many features in use
E.g. does face detection slow things down more etc
tawdry pivot
XCode Instruments has some great GPU profiling tools
drowsy solar
I'll give that a whirl, makes sense.
tawdry pivot
And yes, your assumption is correct, the more pressure you put on the device, the more likely it will be for the camera to lag
If it's easy enough for you to turn off features to test, you could try to see (by process of elimination) which ones are the biggest users of resources. That coupled with xcode's profile tools should help you out on iOS at least.
drowsy solar
I'll give that a try, thanks for the info

although ive updated my unity to 19.3.3 now, will that have changed it?
ive downloaded and imported the newest package fron the vuforia website too
like it shows up in packages under Vuforia Engine AR but doesnt show up in player or project settings

Open the launcher and look at your installed modules. Pretty sure you need it for each version, considering it’s integrated
earnest mirage
It's not showing as a module, I thought it was just automatically integrated with the newer versions of Unity? 2018.4 has the option to add it as a module, but 2019.2 doesn't, nor does my current release of 19.3
hybrid perch
Oh really, hmmmm in that case I’m not sure
It’s listed here for 2019.2, I don’t have my computer so I can’t look into it https://docs.unity3d.com/Manual/vuforia_get_started_project_setup.html
earnest mirage
its alright!
ive followed the guide, Vuforia still doesnt show up in the player settings but all the functionality works so im taking it as a win

AR Foundation question. Is it possible to combine plane detection with image targets? I would like the user to scan the floor (for a stable track) and then aim the camera at a painting to get information about the painting on the screen or maybe even a 3d character telling about the painting while standing on the floor plane
hybrid perch
Yes @glossy abyss you just attach both scripts to the AR Session
glossy abyss
follow up question on my AR Plane detection and image targets. Lets say I have scanned the floor. And when I scan an image I would like to show a 3D Model of a human standing on the scanned floor. So 1 way to do that is to meassure the distance from the image target to the floor in the real environment. However if the image targets sometimes change from position I have to re meassure everything. Is it possible to place it on the scanned floor without meassuring the distance from the image target?
wide steeple
@glossy abyss could you elaborate? What do you mean by "image change from position"? What are you measuring?
solemn oasis
At that point I would raycast from the image position downwards then instantiate the model there.
@glossy abyss
hybrid perch
Agreed. We do the same thing in our app but the markers are static and never move. If they change around you need to rely more on the AR planes
glossy abyss
guys thanks. guess Im living in a different time zone. Sorry for the late response.
@wide steeple well let's say I'm building an app for a school which uses paintings as image targets. They want to use the app for special occasions. However the paintings are placed by the students on tables or on the wall depending on the location. So there is not a static distance to the floor meassured from the image targets.
@solemn oasis thank you that sounds like what I need. Can you point me in a direction where I can start? Are there tutorials about this matter?
solemn oasis
Does your plane have a collider?
If so you can put a raycast downward in the imageTracked method
On startTrack instantiate the model. On updateTrack reposition it
wide steeple
@glossy abyss I'd try to 1) define which plane is the floor first (maybe ask user to scan it), anchor it 2) place the narrator on the floor near the image when you detect it - if you have the floor plane you'll already know it's Y coordinates, so you could place the NPC say to the right of the picture, on the floor
glossy abyss
@wide steeple and @solemn oasis thanks they both sound as good methods. wish I knew more about programming instead of being the 3D guy. Are there any samples available containing this solution?
wide steeple
@glossy abyss I can recommend looking at 8thwall samples
They are for JS but the principle is similar
glossy abyss
thanks will take a look! 😄
solemn oasis
@wide steeple Great points I was trying to make a one size fits all solution
How does AR handle sloped floor? Because in that case you could raycast downward and place it according to the normal.
wide steeple
Don't recall when I saw a sloped floor last time)
Will not the NPC look like he is glued to the floor in that case? :D
solemn oasis
Yeah I suppose it depends on the angle. Might have to go with some crazy procedural animation in that case ha

question about AR object tracking. With ar kit you can scan the object and it creates some point cloud data which you can save to import later in your unity project. With 3d laser scanners you have available these days wouldnt it be possible to scan it with that and import that data in unity? would reduce time if you have a lot of objects you want to interact with.
hybrid perch
You can do that with ARKit as well @glossy abyss
There was a dedicated app for scanning objects and storing the point cloud
You can see it here https://www.youtube.com/watch?v=5uyqOX3nSyI
I see your point about laser scanners but they create extremely high density point clouds, which would not work on a mobile devices. In addition, the algorithms for generating points will mean the output from scanning the same object might not be the same
glossy abyss
@hybrid perch thanks that makes sense. ill stick to manually tracking then
tame drift
I'm completely naive as far as AR goes. Can I use just Unity and my android phone to create an AR button that I can actually "touch" and make it do something like change it's color ?
Or will I be limited to just seeing things that I can control with my actual touchscreen on my phone.
wide steeple
@tame drift you can "touch" it with Manomotion or just tap on the screen and use a raycast

Question about motion capture, is it possible to use ARKit 3 to record motion capture animation, i have a project where we have looked into using motion capture and was thinking of using ARKit + Unity.
tame drift
@wide steeple So I need to use external tools that appear quite pricey too 😦
and yeah the tap on screen is always an option I suppose.
wide steeple
Yeah, tap should be enough in case you are not making a headset-only app
