There's also a native hand tracking library from Google, which is free but isn't wrapped in Unity plugin

hmmm probably will look into that

#

ty for mentioning it !

solemn oasis Jan 21, 2020, 8:59 AM

#

@marble fossil I fear it won't be accurate enough but it depends on the desired animation framerate and use.

marble fossil Jan 21, 2020, 9:33 AM

#

@solemn oasis So it is possible to use it as a motion capture rig ? Can you point me in the right direction ? I have only been able to find stuff for realtime use 🙂

solemn oasis Jan 21, 2020, 9:44 AM

#

@marble fossil Yes but I would look into Mocap Assets because recording in realtime and translating to a humanoid rig might not integrate well.

marble fossil Jan 21, 2020, 12:15 PM

#

@solemn oasis The thing is we need speaking animation so we would love to make a setup where we can track the face and then read the script 🙂

Just strap another iPhone in front of their face for that

@marble fossil https://twitter.com/DanMillerDev/status/1216725207773106177?s=20 I worked on some motion capture stuff with ARKit 3.0. You can see the level of fidelity in the playback. I added the ability to import it into Unity and using the https://docs.unity3d.com/2019.2/Documentation/ScriptReference/Animations.GameObjectRecorder.html API output an animation clip.

Dan Miller (@DanMillerDev)

Worked on a #ARKit 3D body capture app that can place the capture back in #AR, replay it, and view onion skins of the capture. It can also share the captured data and process it in @unity3d, which creates an animation clip that can be applied to other models. #madewithunit...

When calling AREnvironmentProbeManager.AddEnvironmentProbe is the probe created at the scene root, or as a child of the gameobject that EnvProbe Manager is attached to?

Does anyone know of any alternatives to Vuforia/Wikitude/EasyAR for cloud image recognition? I see plenty of machine learning based solutions for image classification, I just want to be able to match an image from the camera feed to an image in a database (i.e. scanning an image target)

#

The reason I don't want to use those full AR solutions is that I'm intending to build the app using AR Foundation

@fossil flower Strangely. I asked @mighty glen about this channel a few weeks ago. And he approved such content based on channel description: "share anything related to ar".

It was a loose statement based on that but @fossil flower has been here longer than me in regards to processes so if he's saying that I'd stick with that 😄

Yep, but we have a dedicated channel for the asset store advertisement, and the post topic hasn't been brought up with any context of conversation. And including with the one I deleted it is getting spammy to repost it outside of the showcase channel multiple times.

Soo...if my android phone doesn't support ARcore...means that I can't really create AR apps ?

#

The only other thing I have is a pc usb camera, can I use this ?

floral summit Jan 29, 2020, 2:41 AM

#

@tame drift You can technically do "AR" by overlaying any feed. AR is just about adding (or 'augmenting') reality. That being said, ARCore/Kit make things easier/cooler by providing tools for depth perception/occlusion.

#

If you think about it, Iron Mans helmet display is AR, but uses no depth

#

From there, its just about what you want to actually achieve

wide steeple Jan 29, 2020, 7:39 AM

#

@tame drift you can use easyar, 8thwall or AR.js instead

#

Also Vuforia

hybrid perch Jan 29, 2020, 8:09 AM

#

Yes Vuforia works with a webcam. They also have a list of compatible devices on their website if you wanna do plane tracking

@half basin you might just want to make a custom dictionary where each element object contains an image and a string associated with it

@atomic badge Well what I did was, make the image targets the same, have two list for image and a text target, and check the name of the elements and if they are same, then i match them. Is that a good way?

Hey guys, I recently updated my Unity version to 2019.3.0f6 from 2019.3.0b4 along with an Android AR project and the app built no longer asks for permission to use camera so I just get a skybox / black screen when I open the app on my phone. Any else have a similar problem? I also tried it with the sample scenes from the XR Interaction Toolkit examples and same thing. I've also added an AndroidManifest to Assets/Plugins/Android with the permissions, but they don't seem to work either.

wide steeple Feb 5, 2020, 10:19 AM

#

@harsh moat Artoolkit or ARKit?

#

Well I guess android means Artoolkit, so one option is to use a virtual camera driver and feed it some photos or video you need to test
That way you can test and develop in Editor directly

Artoolkit for android

Is this hard to setup

So I've been using Vuforia for AR based programs in unity in the 2018 version, when I updated to 2019.3, the application wont run anymore because Vuforia is no longer native. Is there a way I can get the app to run on 2019 without doing a complete rebuild?

@dull swallow not native as in goes as a separate asset package?

dull swallow Feb 17, 2020, 7:20 AM

In the 2018 version you can download it as part of Unity, in 2019 you have to import it as an asset.

#

anyone can help me on my problem ?

#

^ discribed upper

uneven hollow Feb 20, 2020, 5:07 PM

#

so the problem is still the same

#

didn't changed anything

supple thistle Feb 20, 2020, 5:07 PM

#

That's surprising. Are you sure arCamera is what you think it is?

uneven hollow Feb 20, 2020, 5:07 PM

#

y

#

actually

#

when i move the object

#

and drag it

#

to make it forward

#

it goes on forwards to it's local roration

#

and not taking my camera rotation

#

so didn't changed

supple thistle Feb 20, 2020, 5:09 PM

#

I missed that you were setting the x and z directly.

#

It would be better to just create the movement vector you want and then add it to the position.

#

So that I understand correctly, when you swipe up, so the deltaPosition.y goes up, do you want the object to move away from the phone?

uneven hollow Feb 20, 2020, 5:10 PM

#

when i swipe up

#

the object should move on the forward axis of the camera

#

if it's swipe down

#

closer to camera

#

i mean

#

not really

#

but it's a drag feature

#

it works

supple thistle Feb 20, 2020, 5:12 PM

#

I think I understand.

uneven hollow Feb 20, 2020, 5:12 PM

#

but only if my camera don't move

#

once i move my camera

#

it's fucked

#

because the world orientation is not the same anymore

supple thistle Feb 20, 2020, 5:17 PM

#

Transform cameraTransform = arCamera.transform;
Vector3 movementVector = Vector3.zero;
movementVector += cameraTransform.forward * touch.deltaPosition.y;
movementVector += cameraTransform.right * touch.deltaPosition.x;
movementVector = Vector3.ProjectOnPlane(movementVector, Vector3.up);
movementVector = movementVector.normalized * touch.deltaPosition.magnitude;
movementVector *= speedModifier;

_lastSelectedObject.transform.position += movementVector;

#

@uneven hollow

#

There's a slight problem with this, in that the drag speed will be slower the greater the angle of view is.

#

I edited the snippet to fix that.

uneven hollow Feb 20, 2020, 5:23 PM

#

wait

#

let me check

#

it's working at half

#

because if i put my phone in landscape

#

it change

#

up become right etc

#

so it's not working perfectly

#

@supple thistle

supple thistle Feb 20, 2020, 5:32 PM

#

Then you need to use a different rotation when in landscape.

#

I'm sure you can figure that one out yourself.

#

Use cameraTransform.forward when in portrait mode, or cameraTransform.up when in landscape mode.

uneven hollow Feb 20, 2020, 5:38 PM

#

on the x

#

wtf ? my messages got deleted

#

Vector3.Cross(m_forwardDir, Vector3.up) * -1;

#

this will do it i thinjk

#

no it doesn't work 😦

#

@supple thistle any idea ?

#

how to take in count the rotation of the phone too ?

#

for the right vector

supple thistle Feb 20, 2020, 5:45 PM

#

Both vectors have be modified.

uneven hollow Feb 20, 2020, 5:46 PM

#

but when i turn my camera

#

it's not working

#

anymore

#

everything is inversed

#

or

#

quarter modified

supple thistle Feb 20, 2020, 5:47 PM

#

If you want to take the rotation of the phone into account, then the rotation of the phone has to be part of your code.

uneven hollow Feb 20, 2020, 5:48 PM

#

look at this

#

                Vector3 m_rightDir = new Vector3();
                m_forwardDir = Flatten(arCamera.transform.forward, _lastSelectedObject.transform.position.y);
                m_rightDir = Vector3.Cross(m_forwardDir, Vector3.up) * -1;
                _lastSelectedObject.transform.position += (touch.deltaPosition.y * m_forwardDir + touch.deltaPosition.x * m_rightDir) * speedModifier;

supple thistle Feb 20, 2020, 5:48 PM

#

Code needs to be in a code block

#

Where is the rotation of the phone in this code?

#

How do you expect it to take the phone's rotation into account if you're not reading it anywhere

uneven hollow Feb 20, 2020, 5:50 PM

#

it's not really rotation of the phone

#

but of the camera

Hi,
I need a bit of help regarding vuforia image feed.
I found on a forum info that we cannot feed vuforia with image from camera instead of live video feed. But at the same time I can see Vivono app which is featured on vuforias website which is using photos to get recognized and do specific action.

I will try to explain my problem better and hopefully someone can help. If not, I will stop bothering you, guys! 🙂

I am trying to create a simple AR app. Imagine I am tracking an image and on top of that image I am spawning Tracked Image Prefab. Let's say this prefab is a model of a dragon with some fire effect on its timeline. And I want to control the prefabs timeline when it is instantiated by AR Foundation. For example, I want to play fire animation with a button click.

Can I put a listener on the prefab to trigger the timeline in runtime? Or somehow tell the instantiated prefab to trigger its timeline. Is it possible? How can I do it, please?

hybrid perch Feb 24, 2020, 10:10 AM

#

This is no different than triggering an event in a regular prefab

#

Have an event that is triggered by your button, and make the prefab listen for that event when you spawn it

If you know the position of the camera beforehand, you can just set up the scene with the floor where you know it is. Then you set up your scene normally, and render the camera feed as the background

Any vuforia users run into this gem when deploying to iOS? sometimes it causes the app to crash, sometimes it works it self out an actually loads the scene... tons of reports on this on vuforia's forums about it, but no actual answers (surprise). The most common solution seems to be changing the graphics API from metal to OPENGLES3 but hasn't seemed to have any affected.

Vector3.Lerp(startPosition, endPosition, 3.0f)
I am trying to make a capsule move from the point it is spawned to another point being tapped by the user. So the startPosition should be the position of the spawned object and the endPosition should be the position of a point on a plane that is tapped by user. I am also using XRInteractionToolkit and an ARPlacementInteractable to place objects on the plane. So basically how do I detect touches on a plane?

wide steeple Mar 5, 2020, 7:58 AM

@blazing cipher you may need to raycast from camera towards the tap point and check collision with the plane

wide steeple Mar 6, 2020, 7:29 AM

#

@glossy abyss you could start with placing your model on tap with some semitransparent shader applied and then use something like Lean Touch to move and scale it to align to the world

#

Or use 6d.ai

glossy abyss Mar 6, 2020, 8:11 AM

#

@wide steeple thanks. What im looking for is that the world spawns directly on top of it instead of moving it. Give the user an experience that they are in a complete different world but still can set in on the couch or chairs for example

hybrid perch Mar 6, 2020, 8:52 AM

I would not say this is feasible with the current state of mobile AR

#

Not in a way that is very realistic to pull of at least, I think

wide steeple Mar 6, 2020, 9:20 AM

@glossy abyss well you could achieve something like that using 6d.ai. It would require a prescan of your area first.

Hello guys quick question using ARFundation, Any of you know how to cast shadow on the ground ? when i'm not displaying the plane i assigned it a transparent mat

jagged patio Mar 10, 2020, 8:08 PM

#

@uneven hollow the issue is that by default transparent objects don't allow shadows to be cast on them. Depending on what rendering you are using you can use this shader which works in legacy rendering. https://gist.github.com/DanMillerDev/96f9a157d56cd6c0480e0e1838d99df6

It allows you to have a transparent object that receives shadows. You will still most likely need to adjust shadow settings to get crisp looking shadows depending on the size of your content. Usually I just create a quad with a material using this shader and put it at the base of my object that gets placed on the plane.

I'm working on getting something similar with Universal render pipeline but nothing out of the box that works with the latest yet.

Hey guys I am trying to create a reference image library at runtime.
I have a static Dictionary which is storing the a bunch of image textures from a different scene of the game. I have a seperate AR Scene and when I go this AR Scene , I am adding a ARTrackedImageManager component and then I want to add all the images from the aforementioned Dictionary to the referenceImageLibrary.
I have some questions regarding this.
When do I actually set the ARTrackedImageManager.referenceLibrary ? before adding the images or after adding the images.
Where can I find some examples of adding images to the reference library?
When using "ScheduleAddImageJob" do I need to wait for this job to end?
I am adding a snippet of the code I have written so far. when I try to logout the count of images in the mutable library it logs 0.

trackedImageManager = gameObject.AddComponent<ARTrackedImageManager>();

        RuntimeReferenceImageLibrary runtimeLibrary = trackedImageManager.CreateRuntimeLibrary();

        MutableRuntimeReferenceImageLibrary mutableLibrary = runtimeLibrary as MutableRuntimeReferenceImageLibrary;

        // Static dictionary of images taken by the user from the rest of the game.
        foreach (Texture2D texture in CreateTrackingImages.trackingImagesList)
        {
            // if that texture exists.
            if (texture)
            {
             var addImageJob =  mutableLibrary.ScheduleAddImageJob(texture, texture.name, 0.1f);
                while (!addImageJob.IsCompleted) {
                    Debug.Log("Adding images");
                }
                addImageJob.Complete();
            }
        }

        if (mutableLibrary != null) {
            Debug.Log("Mutable library with images was created " + mutableLibrary.count);
            trackedImageManager.referenceLibrary = mutableLibrary;
        }
        
        trackedImageManager.enabled = true;
        trackedImageManager.trackedImagesChanged += OnTrackedImagesChanged;

Hi, does someone succeed to build native app on android, with unity as a library and ARFoundation or ARCore install with the package manager?

#

Our app work without arfoundation or with arcore install in plugin directory

#

When we try to build a projet with ARFoundation we have the issue below

#

`FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':unityLibrary:javaPreCompileDebug'.

Could not resolve all files for configuration ':unityLibrary:debugCompileClasspath'.

#

anyone knows what is ARPlane.useGUILayout there is nothing in the docs about that ... i c there is a canvas renderer attached everywhere planes are used in the samples - is that it i wonder ?

#

@balmy grail was there anything else changes besides adding ARFoundation to the project ?

#

@viscid lynx can you show us the function wrapper ?

silent dune Mar 16, 2020, 12:37 AM

#

would learning AR right away as a Unity newbie be too hard?

#

I've had experience programming games in Godot but AR completely overwhelms me

#

you guys have any tips?

hybrid perch Mar 16, 2020, 7:46 AM

#

Probably best to try some simple projects first to get into how Unity works. Most of the AR tutorials out there are meant for people familiar with Unity

main kayak Mar 16, 2020, 10:53 AM

#

just download the sample project from the unity github

#

and study their code

#

it'll make sense

silent dune Mar 16, 2020, 4:47 PM

#

thanks very much for the tips

#

also can AR be used with 2D stuff right now

#

or is it strictly 3D territory?

hybrid perch Mar 16, 2020, 5:32 PM

#

What do you imagine a 2D AR game to be like?

silent dune Mar 16, 2020, 6:34 PM

#

no idea

hybrid perch Mar 16, 2020, 6:36 PM

#

it sounds kind of contradictory to me - the idea of AR is to combine computer graphics with the real world. And the real world is 3D 😄

silent dune Mar 16, 2020, 6:37 PM

#

just wondering if 2D is even possible

#

as I have little experience with 3D

hybrid perch Mar 16, 2020, 6:38 PM

#

It's definitely possible, you could play mario on the table in front of you

silent dune Mar 16, 2020, 6:42 PM

#

well that's one application

balmy grail Mar 17, 2020, 2:21 PM

#

@merry fossil no, sample project with only ARFoundation and a very simple scene.

merry fossil Mar 17, 2020, 2:53 PM

#

@balmy grail
did u use the same unity version

#

as provided in the sample project , or did you upgrade / downgrade to a diff version ?

balmy grail Mar 17, 2020, 2:55 PM

#

no when I say sample it's juste a sample scene we made not another project we import

#

we juste create the project with 2019.3 and install ARFoundation with the package manager

strange summit Mar 18, 2020, 5:23 AM

hey guys I just want to know if the body/people occlusion of AR kit works and how do you know that its working? im currently cycling through the previews of the 3.1.0 versions of AR Foundation and ARKit right now and body/people occlusion doesnt work

next elm Mar 18, 2020, 8:37 AM

#

Is it still problematic to have multiple prefabs with with multiple targets in AR Foundation? I tried it few months back and it was much harder to do with ARFoundation than with Vuforia. I need it to work on Android and iOS.

strange summit Mar 18, 2020, 11:35 AM

#

hey guys about the body/people occlusion of AR Kit how do I know if its working? does it take time to load? with there be a mesh that'll wrap around a detected human if it works? I've tried all the preview versions of ARFoundation, ARSubsystems, ARKit and people/body occlusion doesnt work at all. Im usinig an IphoneX btw

#

please guys I've searched everywhere no tutorials work and as far as I know there is no way to check if this feature is supported on my device or not. and ive searched on the forums no one has any information on this. . .

remote coral Mar 19, 2020, 4:13 AM

#

back in the early days of ARKit, Unity gave us access to the beta package that mapped to beta iOS. Is there a place we can see what's happening in beta AR Foundation? Or, I guess another way of asking is, what is Unity's schedule compared to Apple's? If Apple is working on iOS 14, when would Unity start putting out packages we could use if we installed iOS 14 beta (like I did back in the early ARKit days)?

strange summit Mar 19, 2020, 5:04 AM

#

@remote coral hey man have you tried the body occlusion feature of ar kit?

remote coral Mar 19, 2020, 5:05 AM

#

I've messed with some of the occlusion stuff. What device are you trying it on?

strange summit Mar 19, 2020, 5:05 AM

#

iphone x

#

I dont know if its working or not

remote coral Mar 19, 2020, 5:06 AM

#

I don't believe it works on less than iphone 11

strange summit Mar 19, 2020, 5:06 AM

#

I followed some tutorials and it just said that I just needed to add the occlusion script on the camera

remote coral Mar 19, 2020, 5:07 AM

#

"ARKit 3.0 People Occlusion feature is restricted to devices powered by A12 Bionic (7 nm) and A13 Bionic (7 nm) processors. iPhone X doesn't support People Occlusion because it has A11 CPU (10 nm technology)."

strange summit Mar 19, 2020, 5:07 AM

#

jesus for real? coz the guy from the tutorial said that it worked on his iphone X

#

fuck

remote coral Mar 19, 2020, 5:07 AM

#

Yeah man. I've tried occlusion on both X an 11 and 11 is def. better.

#

There's a lot of the new features that don't work on X

strange summit Mar 19, 2020, 5:08 AM

#

sorry about the cussing got damn. . . I've been tinkering on this all week. . .

remote coral Mar 19, 2020, 5:08 AM

#

Yeah. Programming, my friend. ¯_(ツ)_/¯

strange summit Mar 19, 2020, 5:09 AM

#

I sent a project to an offshore client of mind with the people occlusion demo and it didnt work on his iphone 11

remote coral Mar 19, 2020, 5:10 AM

#

Yeah, but that could be who knows what. If you don't have the device to test yourself it's kind of a crap-shoot imo.

#

I anticipate having to update devices frequently while AR (on iOS and Android) continue to evolve, and the devices gain new capabilities. It's going to be unstable on the bleeding edge for a while, I think.

#

Which is why I want access to all the beta things. haha

next elm Mar 19, 2020, 8:57 AM

#

How do you send an ios project to a client, please? I have always build a project to their devices, but I am wondering how can I send something like an .apk on Android.

hybrid perch Mar 19, 2020, 9:00 AM

#

We use TestFlight to do this @next elm and it's really painless once you know how it works. It can take a bit of time for a build to be uploaded though

#

The only other real alternative is either to add their device to your organisation and build an .ipa file, or send them the XCode project and let them build it themselves

next elm Mar 19, 2020, 9:24 AM

#

@hybrid perch Thank you! Very helpful informations. I will check it out. 🙂

nimble fossil Mar 19, 2020, 9:28 PM

#

One quick question. Is vuforia still the way to go for AR?

hybrid perch Mar 20, 2020, 7:42 AM

#

Depends on what you want to do. It's pretty stable, but it's also more of a black box. AR Foundation works pretty well

nimble fossil Mar 20, 2020, 7:14 PM

hey guys i bought a argumented reality bow but i´m stuck becouse i thought the connection would be bluetooth from options of the android phone but in fact it connects though the app, but what i really want is to use the bow in my own game, is there a way to connect to the phone outside of the bow made games?

It is still bluetooth but only works inside the prebuilt app

Hello, I need help with Vuforia's ground plane feature.
I want to place an object at certain position when the player gets within a certain distance to a gps coordinate. I've already finished with tracking the gps position, and all that is left is to figure out how to use the ground plane feature.
The docs on vuforia's developer portal are absolutely uninformative. so, looking through the ground plane example from vuforia core samples, i found that InteractiveHitTest and AutomaticHitTest do something when performed. But i have no idea what they do and what's the difference. Can somebody explain this to me? thanks.

Hello everyone , is it possible to achieve face to face multiplayer AR with ARFoundation (for androids) without using Reference Points?

golden escarp Mar 26, 2020, 12:52 PM

#

@grand tangle used it, don’t get why it’s such a big deal

grand tangle Mar 26, 2020, 1:15 PM

#

@queen phoenix you will want to use some point of reference if everyone's supposed to see the some stuff at the same place. If that's not necessary you won't need one

queen phoenix Mar 26, 2020, 1:40 PM

#

@grand tangle thats necessary for everything in my scene but if thats so, is there any restrictions about how many Reference points may i use?

grand tangle Mar 26, 2020, 1:42 PM

#

Think about if you only need one to set the world center. Set one gameobject to this point and nest everything else under it. The local transforms then have to be synced only via network. No realworld refs needed anymore.

#

The less Reference points (do you mean world anchors?) you need, the better..

queen phoenix Mar 26, 2020, 1:43 PM

#

Wow, thats means the world for me, thanks for the advice

#

yy i noticed that they changed cloud anchors

to reference points

anyone knows how to make the shadow of the model more realistic?

#

and how to avoid the drifting foot...

fresh basalt Mar 27, 2020, 3:39 PM

#

@tight plinth if by "drifting foot" you mean that the anchor wobbles around it's fixed position, from my experience it gets better as the device's understanding of the environment improves. However, how to actually measure and improve the device's understanding is beyond me.

#

I've tried adding cloud points and plane managers to see if it would affect in any way (as I'm building on Android and ARCore states that it improves by detecting feature points and planes) but it has been inconclusive

#

so I'd love to have some insight myself

@jagged patio Hello! Looks great! Thank you for sharing this stuff. What do you think, is it possible to add to the UX scene the transparent/ghost preview of the object? Apple implemented this feature in Web AR, so it looks like a new AR guideline

potent field Apr 1, 2020, 4:19 PM

#

Hey friends I have a question, I am working in a project with AR foundation, I need to allow users to move an object in an infinite plane, not the plane that AR detects. It is like I have to place an infinite plane in the ARPlane user selects, and then just work with this new plane. But I am getting in trouble trying to move the object in this new plane. Someone has had some similar problem?

I was trying first with
if (_arRaycastManager.Raycast(touchPosition, hits, TrackableType.PlaneWithinInfinity) and it never worked, I guess I don't understand what they mean with "infinity", so I was trying to place a 3D big plane in the position of AR plane and move the object on it, but I don't know how to do that, I guess I should not use AR RaycastManager since it's not an ARPlane

Anyway if someone has an idea about this "infinity plane problem" I would be thankful

finite rose Apr 1, 2020, 4:55 PM

#

yea i would just use the ar raycast manager to place a really huge plane mesh first and then just raycast against that

potent field Apr 1, 2020, 4:59 PM

#

but raycast with physics.raycast or plane.raycast, I don't know I guess I am getting so confused :C

#

?

finite rose Apr 1, 2020, 5:00 PM

#

all colliders have their own raycast method

#

so just make sure you have a collider of some kind on the plane and call it directly on that

#

i.e. BoxCollider.Raycast

@jade pewter sure I can create a small example showing that. I assume you're talking about AR quicklook which shows a transparent object and snaps to feature points and then goes opaque and is placed when a plane is found?

Right, i've only done that with ARCore, not with ARFoundation. I don't think it's supported but have you tried just using them as image markers?

toxic arrow Apr 20, 2020, 6:16 AM

Hi Guys,
I'm trying to find if AR Foundation does have an event that is raised when the session tracking is lost/relocalized ?

short wolf Apr 20, 2020, 7:46 PM

#

@toxic arrow i cant find a event but you can check ARSession.notTrackingReason , if its None its woking fine , if not you are getting the reason why its not tracking.

@grand tangle , hey there ..We ve talked some days ago about a multiplayer AR app which i am developing.
I tried the idea with the one anchor u told me about and i ld like to ask if the best way to connect my 2 devices is via the network manager

grand tangle Apr 21, 2020, 11:04 AM

#

@queen phoenix This depends on your needs (which I can't remember 😅 ) if you're on a local network and only want to share your anchor there, Network Manager is a good option (which I use primarily for my stuff). Over Internet, there are various other options from Google (Cloud Anchors) or Microsoft (Azure Anchors) which work cross platform as well.

Haha. firstly ty for ur feedback 🙂

It will be face 2 face multiplayer AR

Hey everyone, I know this is Unitys discord, but does vuforia / Unity work in web browsers on mobile or do you have any alternative to use object markers (talking about a cube to be scanned) with another library like AR.js or similar?

Because there are two things that can fail here, I think you should do some Debug Logs to figure out what is not called

#

Either the raycast is not hitting, or the strings are not the same

#

Btw you shouldn't use string == string, it's better to do text.Equals(word4)

Hey everyone! I hope you are well. I know that with a majority indie game group or a production in crunch time (and it seems to always be crunch time) group you may not have the time, energy, or bandwidth to answer, but if anyone would be willing to give me some pointers and tips for minimum qualifications for an entry level job in this field I would really appreciate some guidance. I am a high school teacher and I have kids working in this space, but I want to ensure that I am not leading them astray in terms of development skills required. Anyone want to teach a teacher a quick lesson on minimum skills for the betterment of your future devs? 😄

fresh basalt May 8, 2020, 9:54 AM

hello fellow nerds, I'm tinkering around with ARFoundation (the device I'm building on is an android one, so, consequentially, ARCore) to achieve an "AR cube" effect. My biggest priority is stability and detection speed from a close-medium distance (20-40cm from the real cube). here's the current state:

#

📎 arcube.png

#

unfortunately, it does not work too well; ARCore does not detect the markers quick enough for a smooth transition from face to face. It makes sense considering it does not benefit at all from aruco markers. My question is if any of you have an insight on what types of images are best suited for ARCore image tracking. The only thing ARCore offers is their "arcoreimg" tool which rates an image from 1 to 100, but when both images have a max rating the only method to see which one is better is manual testing.

#

given they are not willing to share the specific details of their feature detectors, I don't know what direction to go in

#

perhaps I'll even consider ditching ARFoundation

finite rose May 8, 2020, 3:43 PM

#

I’ve only really worked with ARFoundation w iOS, but in my experience there, high contrast images track the best so the images you are using seem like they are already optimal... maybe ARCore detection is just a little slow?

fresh basalt May 8, 2020, 5:14 PM

#

maybe indeed!
it also appears to work better with high-contrast images with many feature points; the other cube that appears in the screenshot seems to have lower detection time despite having more feature points to match and being a smaller cube

finite rose May 8, 2020, 5:48 PM

#

oh interesting, but that kinda makes sense.

wanton turtle May 8, 2020, 11:15 PM

#

@vocal bluff it's mostly timing, portfolio, and cultural fit. I'll send a technical challenge after. But the truth is - at red iron anyways - bring a cultural fit to the team and our values is far more important. I can teach technology - I can't teach attitude. But we are probably very different from other studios

#

We hire in 4 groups through throughout the year. Entry level, junior, intermediate and senior.

#

Knowing additional fields helps a lot. 3d modeling + AR, means I see you as being able to do two different lines of projects

#

We just wrapped up our entry level hires, and are taking on 3 of them.

#

Next will probably be another senior dev round

vocal bluff May 8, 2020, 11:18 PM

#

@wanton turtle I totally get that. I try to have my kids work in teams for projects partially so that they understand how to communicate and collaborate. Sometimes my best technical coders have to learn a lot about how to work with others, understand the need for client/end user communication, and how to blend with other people.

#

At the end of the day I figure that there are lots of tutorials on basic data types and how to build for xyz platform. Way less you can watch that helps you learn to work with other people on a project.

#

I really appreciate that feedback.

#

Thanks for taking the time to respond. Would love to know about some of your projects sometime.

#

@wanton turtle What would a good portfolio showcase for someone trying to get one of those entry level positions? Is there a specific set of skills you would be looking for? An understanding of pipelines? Multiple types of AR development for different platforms?

wanton turtle May 8, 2020, 11:34 PM

#

@vocal bluff it's helpful if they launched anything on their own. Then I know they know the workflow, release, launch, online sharing etc. I'm not so worried about their framework - they have to do an online course when they join us. But I am assessing if it looks great, feels fun. I want to see unity or unreal knowledge. I'll go through their code in the technical challenge super carefully.

#

They need to be able to work alone to try things but come to a team member once stuck

#

I'd say 2/3rds of our applicants we exclude because of the cultural fit. The last 1/3 we assess their current value and future potential. From there we do the technical challenge to verify our understanding.

#

So if we assign the technical challenge it's because I am seeing a potential where we will hire them

#

We are about 80% VR, 10% AR, 10% other

vocal bluff May 8, 2020, 11:38 PM

#

@wanton turtle Just so that I am clear, when you say launch something do you mean through an official store? This year we had our first actual release of a project for a local client to the Apple app store, but when I think of the requirements to launch a HoloLens app or a Vuforia app completely solo...that's a big ask for a high school kid. When you look at the requirements to get something in the Oculus store, especially for the Quest that sounds...difficult.

wanton turtle May 8, 2020, 11:38 PM

#

I'll ask about SteamVR, VRTK, ARCore and ARkit. But as long as they know any of them it's OK with mr

vocal bluff May 8, 2020, 11:39 PM

#

Does releasing something to something like SideQuest or something like that count?

wanton turtle May 8, 2020, 11:39 PM

#

That would work, just gives them an edge if I know they understand what it feels like to upload an APK, and submit it for review, and see what it's like to share it on Twitter or online

#

It doesn't exclude them, but compared to another applicant, it's a big edge

vocal bluff May 8, 2020, 11:40 PM

#

Ahhh...totally get that.

wanton turtle May 8, 2020, 11:40 PM

#

Same with 3D modeling or graphic design or PM or QA experience. Something that I know I can fit them into the company better and on more projects

vocal bluff May 8, 2020, 11:41 PM

#

Totally get it if you wouldn't want to, but if you are willing could you give me an idea of the level of the technical challenge? I won't give it as an assignment or anything...I just want to see the level of difficulty so I can plan for it.

wanton turtle May 8, 2020, 11:41 PM

wanton turtle May 8, 2020, 11:43 PM

#

We have 3 sister studios. One is very formal, they go based on academics. One is more artistic, their hiring is a 1 year process. And the other is our US team, and they hire based on knowledge, salability and desire

vocal bluff May 8, 2020, 11:47 PM

#

There aren't too many studios in my area...and none of the ones I have met anyone from are doing any work with xR. People in my community are, but most have defense contracts and my kids can't do anything with those companies. So...it has been a wild west trying to figure out what they need to know...what they should be able to do...where they should be investing their time...or any one of a hundred other questions. With how fast things have been changing with toolkits and hardware and the lack of overall standardization (though it seems to be coming) it has been difficult to stay current and also have them creating meaningful stuff.

#

Super helpful to have at least a smaller kind of target set to shoot for.

wanton turtle May 8, 2020, 11:50 PM

#

Oh yeah! It's the same here. The 4 of us as studios share a lot of work and applicants and grants with eachother. And in our case we partnered with 4 schools, and get most of our auxillary hires from there. And then I use local community events. We don't do LinkedIn or standard recruitment, I look to our local GameDev community for a lot of our key roles

#

But we are small, 18 or so. Our US team is another 10 or so. And our two local partners are 30 ppl and 12 or so.

#

So very small teams generally speaking

vocal bluff May 8, 2020, 11:53 PM

#

It was funny this year because I was tasked with setting up internships for my students. The only issue was that when I tried to find anyone making AR handbooks/apps or VR museums I couldn't find anyone. So, I partnered with local museums and businesses and then just had the kids work under my direction for the partners as clients; not the same as an industry internship, but it was the only way for the kids to produce work for an authentic external audience because none of our partners could actually advise them or tutor them on the development side.

#

I mean...funny...but also exhausting...and if I am being honest a little scary. I don't know how to run a software development company, and while I don't have to worry about the overhead of ensuring money generation or HR type requirements, navigating the legalities of students making software for clients felt very businessish to me. So much learning about how to release and package and do QA.

wanton turtle May 8, 2020, 11:59 PM

#

That's awesome! Yeah. It's weird, there is either a bunch of studios in an area or none. I love your approach, and I think it's a great way to tackle the problem. It can be tough at times - like we are always craZy busy. It's a combination of software and digital media. So an odd space to work in :)

Hello, i want to ask question.
Im using ARCore from unity package and try to use plane detection horizontal and vertical. Im wondering, how can i place object specifically in horizontal for example while both of plane detection is selected? (There is object that can only placed in vertical and also object that can only placed in horizontal)
Thank you~

fiery stone May 12, 2020, 5:32 PM

#

@marsh ibex If I understand you correctly, you want to be able to place an object on horizontal surfaces, but not vertical surfaces in the world, correct?

marsh ibex May 12, 2020, 5:36 PM

#

yes

#

so i want 'a' object place only in horizontal, and 'b' object place only in vertical

fiery stone May 12, 2020, 5:38 PM

#

Admittedly, I do not have a lot of experience with ARCore, but this seems like a linear algebra problem.

Since I haven't worked in ARCore, give me one second to look through the API documentaiton

marsh ibex May 12, 2020, 5:39 PM

#

thank you

#

i will try re read documentation again

fiery stone May 12, 2020, 5:43 PM

#

So it looks to me like you can get the normal of a generated plane based on the "CenterPose," Are you doing this yet?

#

You can find that information here "GoogleARCore.DetectedPlane"

#

The orientation of the CenterPose is the normal of the DetectedPlane. If you have the normal of that plane, you can take a dot product of the plane normal and Vector3.up to determine if there is any horizontal component to the plane you are colliding with. You will need to determine a threshold for what is "Horizontal" vs. "Vertical". If the detected plane is sitting at <= .707f when you take the dot product, then you are at an angle of 45 degrees or more from horizontal. In this case, maybe you consider that a vertical plane. You could create a tolerance that is very small, something like .95f, and this would give you a plane that was nearly perfectly flat. Same concept for vertical, but when you take the normal and dot it with the world up, you want to get something <= Mathf.Abs(0.05f), indicating your wall's normal is almost perfectly perpendicular to world "up"

#

@marsh ibex

#

Code you would need:

Vector3.Dot(CenterPose.Orientation, Vector3.up) >= Tolerance
I don't know what the CenterPose.Orientation variable is actually called. It might be "rotation" or something. If "rotation" comes back as a quaternion, you'll have to convert it to a vector for my example

fiery stone May 12, 2020, 6:18 PM

The way the code is written, it should place objects on vertical walls if the raycast hits a wall. If I understand you correctly, you want to have vertical plane detection on, but you only want to place certain objects on vertical planes, not all objects, correct?

There is no VUFORIA CODING EXAMPLE out there? How can we learn structure of the classes. How can I learn the library? How did you learn?

#

Anyone who heard there is a program called "Vuforia" had taken tutorial but not worthy. All of them are garbage. They say, drag the fc thing here, drop it out. Please if you encounterd before, share a link to me. Thank you

Hey fellow Coders!
I have newer worked on AR before and would like to give it a shot. Can you guys help me with where to begin with.... I am thinking of starting off with basic like

#

You got a package conflict I think. Go into package manager and remove the XR plugin. Also, make sure you use the same Unity version as they do in the video as this is probably why this is occurring

@regal seal yes that is the case, the video was recorded in 2018.3, while i am using the current latest version

But how to use this is this version?

regal seal May 19, 2020, 6:37 AM

#

Right, So do you have Unity hub installed? @eager sandal

Wait, first, do you want to know how to get it working in the latest or how to download 2018.3? I can't tell if that is is supposed to be an in

is there any source code for a simple paint app with ar foundation?

analog pine May 20, 2020, 6:21 PM

#

In Vuforia, when I use Ground Plane Target, the model to be augmented upon the ground is to be loaded from the asset bundle. So, I wrote a code where the model becomes a child of Ground plane and is then instantiated in the scene, but on tapping on the Ground, it isn't getting augmented on the ground plane but it is staying at 0,0,0 WRT to the camera.

But when I use Image Target, it gets instantiated at 0,0,0 wrt to Camera but on image detection moves to the 0,0,0 WRT to the image.

What could be the possible reason and how can I get it augmented on the ground plane ?

hey folks I was just wondering would i be able to use Vuforia to create an app/site that allows you to try on clothes?

Hello! When you work with ARFoundation, how do you try your game? Is it possbile to try in editor with webcam ?

I did not figure it out how to do. Because, in learning process, most of the time is wasting while making build.

Not at the moment @steep cosmos, you need to build. But you can look up MARS on unity’s website to see what’s coming

How can we send a raycast or trackables things?

vital summit Jun 2, 2020, 11:14 PM

#

Two approaches for raycasting with MARS that we recommend

#

You can either use a replicated proxy that builds a collider, or add a collider or tap script to the visualized plane prefab, and then do raycasts against physics like a purely digital app

#

You can see an example of this in action with the game template

hallow idol Jun 4, 2020, 7:52 AM

#

Hey, did anyone manage to turn PostProcessing off for ArBackground and only apply it to objects placed within the scene. My problem is that as soon as I turn PostProcessing on for ArCamera planes detection starts working really bad and the planes themselves become unstable

analog stirrup Jun 4, 2020, 8:39 PM

#

@quartz lichen I'm not sure about using those specific tools with ar tech in general. They usually increase drawcalls and lead to performance issues depending on which devices you use. Phones in general won't be able to handle them. this is why when developing an app, the shaders and tools used for computer and console based apps are completely different from the tools used for phone based apps or something like the hololense.

quartz lichen Jun 5, 2020, 5:06 PM

#

@analog stirrup oh, that's why it was showing glitches kind of effect too.May be these are too expensive for mobiles to handle.Thanks for clearing it out!

#

@hallow idol I believe you are facing same problem as mine,post processing is expensive for ArCore,you can just remove the scripts and component of post processing from your scene.

modern sparrow Jun 5, 2020, 8:24 PM

#

Hi, is it possible to simultaneously use ground plane tracking and image tracking with ARFoundation?

#

I need to place an object on the ground and then scan an image to activate the object

jagged patio Jun 5, 2020, 8:35 PM

#

@modern sparrow yeah that is possible. You can add both Managers and they will work independently.

modern sparrow Jun 5, 2020, 8:37 PM

#

Awesome, thank you! 🙂

jagged patio Jun 5, 2020, 8:38 PM

#

For post processing as others have mentioned it can be expensive on mobile. I've had some success with limited effects.

@quartz lichen Shader graph is supported just make sure you've configured AR Foundation to use the universal render pipeline.

@hallow idol this is a challenge in general since post processing applies to the entire screen. There currently is not a system to limit the effects to just objects (ie: not apply to the camera feed as well).

Hello collegues! I have a question. Unity - AR Foundation - Image Target - how to detect if i am lost tracking Image - Target ?

jagged patio Jun 5, 2020, 8:46 PM

#

@cinder fiber you can get a callback when the Image manger tracking state changes and then check the associated list of images's tracking state. Here's a code snippet that does that https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/ImageTracking/Scripts/ImageTrackingObjectManager.cs#L121-L148 it's part of a larger image tracking sample I worked on available here: https://assetstore.unity.com/packages/templates/ar-foundation-demos-image-tracking-164880 with the repo and additional documentation here: https://github.com/Unity-Technologies/arfoundation-demos

hello

#

i have a question regarding vuforia

#

anyone here

#

ok imma say the question anyways

#

so im using vuforia with unity and have a 5 star image target, i have loaded the database into unity and made an empty object with a sprite renderer with like an image and made that object the child of the image target so everytime the image target is tracked the sprite appears

#

everytime I run it or build to android once the image target is tracked, the sprite appears but then disappears immediately

#

in the console it shows that vuforia is actively tracking but the sprite is still not there

#

can anyone help?

#

ive used vuforia before and the same method worked perfectly on another project

#

someone heellpp

#

plezzzzzzz

jagged patio Jun 5, 2020, 9:17 PM

Hi everyone, I have a question about ArFoundation.
I'm using it with Android and tracking multiple surface, but it's really unstable.
It detect many surface on the ground on the same place.
Is it possible to constrain it ? And What kind of surface/ground make a better tracking ?

jagged patio Jun 6, 2020, 5:45 PM

#

@dark frost the planes should merge into a larger plane automatically when found around similar areas. You can constrain the planes to horizontal or vertical surfaces so it only finds one or the other. Performance is on a per device basis, are you doing anything other than plane finding in the scene?

dark frost Jun 6, 2020, 5:46 PM

#

no, I only use plane but I want many surfaces where my player can jump from a table to ground..
But on the same ground, it detect different surfaces but not same depth, or it create plane too fast and yes it merge, but still it create a few of them

#

For now, I just detect new planes and add few props on it. And then a player with joystick ^^

#

I also add ARReferencePoint on planes

jagged patio Jun 6, 2020, 5:48 PM

#

I see, you can stop plane finding by disabling the PlaneManager, what device are you running on?

dark frost Jun 6, 2020, 5:50 PM

#

Samsung Galaxy s7 edge with Android 8.0
but as I told you, I really want to continue detecting planes if I move in my room, I start tracking my ground and then my table or any other surfaces in my room. But I need a stable spacialization I guess.

dark frost Jun 6, 2020, 6:07 PM

#

📎 20200607_025726.jpg

#

I got this kind of trouble where I have some planes on the same place but differents depths. I just need one on this surface and the possibility to get new ones when I detect a new surface (Wall, bed, table, chair,..)

jagged patio Jun 6, 2020, 7:58 PM

#

Interesting, yeah I'm surprised those planes aren't merging. It looks like you've got some content / scripts running so try pairing it back a bit and just look at the plane detection. If you're not hitting frame rate (30 FPS for ARCore) you will have some issues.

Hello. I'm new. I didn't understand this error message. What should I do? 😕

📎 unknown.png

jagged patio Jun 6, 2020, 11:07 PM

#

In general if a type or namespace is missing you are missing a package, an SDK, or something in your project that enables / contains that class.

'SpatialTracking' does not exist in the namespace UnityEngine. This means you are missing SpatialTracking class which depending on your version of Unity could be in the XR Legacy Input helpers package. You may have to go to package manger and download or update this.

I am not familiar with MessageBase or where that comes from.

It looks like you are using the standalone ARCore SDK and trying to work with cloud anchors. I'd suggest a couple different approaches.

use AR Foundation instead of standalone ARCore SDK unless there is a specific feature only enabled in ARCore standalone SDK you need.
if you are using AR Foundation and want to use cloud anchors check out the AR Foundation extensions package, here is a getting started guide to setting that up in Unity https://developers.google.com/ar/develop/unity-arf/quickstart-android

Hey Guys, I'm currently working on an AR game where objects are randomized within a 20meter circle. Right now I'm instantiating in the center of the circle which seems to work fine, on the center object, but objects in the distance seem to shift when stepping sideways.
Any idea on best practices for large playing areas? I looked into GPS it isn't very accurate, and seems to not work unless the game is initialized facing true north

#

I'm thinking of plane detection or point clouds. Does that make sense on a grassy field?

unique gale Jun 8, 2020, 12:39 PM

#

anyone know about device location? i know how to get the device coordinates but how i do i know the coordiantes 2 meter form the device? how does it work?

jagged patio Jun 8, 2020, 3:30 PM

#

@unique gale 1 unity unit = 1 meter so if you want an object 2m from the device you can use the ARCamera object as your root / center and place something based on it's position+2

#

@hard plank how are the object's being anchored 20m away? Are you raycasting against a plane and then putting them 20m away from the child object near by or just saying "place an object 20m away from where I am now". I think the early suggestion of an 'offset' object. Like you have an empty parent GO and a child object under it that is 20 units away. You'll still see some drift depending on the device and tracking but that might be more stable. Keep in mind too small shifts you see up close get increased and more noticeable the further an object is away.

unique gale Jun 8, 2020, 3:44 PM

@jagged patio but i want that object stay where i put it after loading the application second time

jagged patio Jun 8, 2020, 3:56 PM

#

ARKit (iOS) or ARCore (android). The issue with consumer GPS is that it's not accurate at the meter level. It doesn't know if you're in the street or on the sidewalk. 2 meters falls within that range. You can try using if it's larger scale objects but with 2m / mobile phone AR I wouldn't recommend GPS.

#

ARCore has Cloud anchors which are accessable with AR Foundation extensions from google. Cloud anchors allows you to find a specifc area, place an anchor and reloalize to it at a later time or on a different device.

ARKit has world maps which allow you to scan a larger area and relocalize to it

I'd suggest looking into these features.

@jagged patio Great Idea, Currently I have an anchor center placed that spawns the models using the spawn points. I'll make the spawn points children to the anchor and change my script to spawn the models as children as well.

Related question, could point cloud help tracking stability? I'm not incorporating any user placement functionality. And the game is meant to be played on a flat grassy field.

no

you definitely would not use HDRP for a handheld AR project.

Hello guys! I have a problem with AR Foundation.
I am always received - trackingImageState = TrackingImageState.Limited when I moved away from image-target, and couple of times while I was faced image-target.
Like :
1 - I am looking on image-target and receive trackingImageState = TrackingImageState.Limited
2 - I am NOT looking on image-target and receive trackingImageState = TrackingImageState.Limited

#

Can sameone help me out?

#

This can cause mistmuch my logic because I put logic with disable AR object inside if (trackingImageState != TrackingImageState.Tracked)

finite rose Jun 9, 2020, 6:06 PM

yea i remember the image tracker api being really frustrating because once an image got tracked, its tracking state would NEVER go back to TrackingImageState.None

@finite rose yea but how i can achieve this? where I am not detect it?

finite rose Jun 9, 2020, 6:27 PM

idk! it's pretty annoying! maybe you can try storing the last tracked position and check if its in the camera frustum or something? unfortunately its a bad API that you have to work around

cinder fiber Jun 9, 2020, 6:28 PM

#

And this frustrating - when first time trying to track image-target I get like 3-6 times Limited before my image get tracked....

cinder fiber Jun 9, 2020, 6:51 PM

#

foreach (ARTrackedImage trackedImage in eventArgs.removed) = when eventArgs.removed happens? btw

Hello guys, can someone recommend free ar toolkit which works fine with text targets? I tried Vuforia AR, but it works so bad with text targets..

jagged patio Jun 9, 2020, 9:13 PM

#

@cinder fiber try checking out this method for managing the lifecycle / state of tracking images.

https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/ImageTracking/Scripts/ImageTrackingObjectManager.cs#L103-L163

Basically you want to check updated list of images from the ARTrackedImagesChangedEventArgs, loop through them.

Check if(trackingState == TrackingState.Tracking)
{
do tracking stuff
}
else
{
do not tracking stuff
}

#

Some of the complexity comes from tracking states between platforms and how they filter back up through AR Foundation

cinder fiber Jun 9, 2020, 10:16 PM

#

@jagged patio thanks, yea I am already going like this, but still have issue with Limited.
What I want to achieve is : when image-target is detected show obj, but in my case else worked 3-6 times before trackingState == TrackingState.Tracking, and like few times inside the trackingState == TrackingState.Tracking,, which is cause issues with my animated object.

jagged patio Jun 9, 2020, 10:19 PM

#

it's been a little while but I would say limited is NOT a good tracking state to check for images. The images derive from ARTrackable which is used in a variety of different subsystems / AR stuff (planes, reference ponts, ect) so while they all have the different states the data is not always correctly populated / passed up through the systems.

cinder fiber Jun 9, 2020, 10:20 PM

#

yea,

#

and that cause a problem with my animated object, like he disabled / enabled 103102313 times per frame

jagged patio Jun 9, 2020, 10:23 PM

#

quite the framerate you're hitting 😝 but yeah there's some things where you can maybe store a counter / time value in the tracking state and only enabled / animate something once the tracking state has been tracking after x seconds. Maybe you can describe your use case a bit more so I can offer some more specific advice?

cinder fiber Jun 9, 2020, 10:24 PM

#

Yea, so :
1 - I have object with coroutine inside ( with which one I am animated the objec, like changes texture over time on it )
2 - When I track image-target I am set active object, and animation will start playing.
3 - When this issue happens with disabled / enabled many times, my coroutine is get bugged and stop working

#

case Type.Mesh:
if (mesh.enabled)
{
Texture2D texture = Helpers.TextureFromSprite(sprites[i]);
mesh.material.mainTexture = texture;
}
break;

jagged patio Jun 9, 2020, 10:27 PM

#

I see, you may want to try and move the logic from a coroutine to an update loop. You can also manage the life of a coroutine and call StopCoroutine on it when the tracking is no longer active maybe? UnityChanThink

cinder fiber Jun 9, 2020, 10:27 PM

#

will try

#

Yea, I will just move code from coroutine to update loop. Thanks

Hello! I'm wondering if there's any plans to make AR Foundation compatible with 8th Wall WebAR. I know 8th Wall had a Unity plugin at one point but it seems outdated. I'm coming from a Unity background but interested in creating WebAR experiences (for now with 8th Wall)

Does anyone have an idea in regards to what's wrong with the AR in the phone?

#

Something happened and when I tested AR when developing my game, it worked properly, but when I tried it in the phone, it didn't work. All it does is displaying the game objects, but nothing else. Is the problem in the building or in the phone and how do I fix this?
Here's the pic of my test when done in unity editor:

this month i want to dedicate to learn AR fondation

is der a good tutorial that teaches from basics?

jagged patio Jun 15, 2020, 7:39 PM

#

@shrewd rivet I always recommend starting with the documentation. https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@3.0/manual/index.html#samples There's some general info about how AR Foundation works and the basic setup https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@3.0/manual/index.html#basic-setup

From there the samples https://github.com/Unity-Technologies/arfoundation-samples and demos https://github.com/Unity-Technologies/arfoundation-demos repo's are good for understanding how to setup and get different features working. In general I think picking a small scope project that you think works well in AR will be a good motivating factor is solving and understanding the challenges of AR and AR Foundation.

Personally I learn best from seeing different examples and breaking down how they work and are setup. The samples repo is perfect for that, I know that's not always the case for everyone but hope this info helps a bit.

This may sound insanely dumb but is it possible to deploy a unity build to the HoloLens from a Raspberri Pi? o.o

hybrid perch Jun 16, 2020, 1:04 PM

Hum, well the HoloLens is running Windows, so it should be doable...

elfin spear Jun 16, 2020, 1:11 PM

I've found resources of people getting the HoloLens and Pi to work together

#

It seems to be that as long as they're on the same network, you can do it

Hello dear people! maybe someone had this issue already? So, with the image tracker, you can see that the 3D Object map doesn't really match the real map, it slides a little bit with the movement of the camera, how can I fix this? and second: I turned off the NavMesh because it was not working with the AR, all the animals where appearing on front of the camera as soon as I turned on the App. I heard I can fix this with "runtime" on the NavMesh, generating it first when the App runs, but how do I do this?

jagged patio Jun 16, 2020, 3:05 PM

@vale lily It's a bit hard to see the image being off but I think I can notice it around the edges. Are you using AR Foundation and image tracking enabled through that? In general the accuracy of image tracking is going to be based on your marker, how it scores / is rated with unique features and ability to be detected by the computer vision. For runtime NavMesh you'll want to use the NavMeshComponents project available here https://github.com/Unity-Technologies/NavMeshComponents it looks like there's a tutorial for setting it up here which might be a good start https://learn.unity.com/tutorial/5c515372edbc2a002069505f

UNVIRSAL RP + vuforia unity 2019.4 getting black sceen from camera

#

google doesnt really solve the problem, there is nice ideas there but most of them are old and not working

jagged patio Jun 16, 2020, 8:57 PM

#

@cunning roost I'm not sure on the support for that, a black screen would typically mean the shader for rendering the camera view is not supported in URP or not properly configured. Does Vuforia link into AR Foundation at all or is it completely separate? There are some extra steps for configuring URP and AR Foundation with the render pipeline asset.

cunning roost Jun 16, 2020, 8:58 PM

#

separate

#

everything work but the camera feedback

#

most of the project is built over vufria and have a part without the camera, now there is a small feature needing the camera

#

so moving to arcore\ foundation is the last option i want to take

viral mural Jun 16, 2020, 9:00 PM

#

there's a Rendering feature for the URP pipeline with ARF called ARBackgroundRenderer feature

#

https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@3.0/manual/ar-camera-background-with-scriptable-render-pipeline.html

#

that seems to be the thing, got me too

#

not sure if it's needed for vuforia

cunning roost Jun 16, 2020, 9:04 PM

#

its need the AR FOUNDATION that my main problem , how it will bheave with vuforia ?

#

@viral mural it doesnt let me have the second option "ar background" in renderer feature

jagged patio Jun 16, 2020, 9:08 PM

#

yeah I think that comes from the AR Foundation package

viral mural Jun 16, 2020, 9:08 PM

#

not sure what the vuforia equivalent is

#

if it even exists

cunning roost Jun 16, 2020, 9:09 PM

#

i added the ar doundation to the project

#

and tried the thing you sent, i cant find the feature when i press add renderer feature

cunning roost Jun 16, 2020, 9:42 PM

#

i was on foundition 2.1 not 4.2 , i update it and now i found this AR feature in the render features, but how do i render the back ground of the camera with ARfoundition?>

#

@viral mural can i just get the background from the ar foundition?

viral mural Jun 16, 2020, 9:45 PM

#

I believe this ties into the ARBackgroundRenderer feature:

https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@3.1/api/UnityEngine.XR.ARFoundation.ARCameraBackground.html?q=Background

TLDR; put it on your camera, doc link has more instructions.

#

and as with anything ARFoundation related, you'll need an ARSession in your scene

cunning roost Jun 16, 2020, 9:49 PM

#

well i am giving the camera a texture so i can past it on my game camera plane

#

cuz the game is using targets and have stuff into it, the background camera is just a small part of the project ^^"

#

i hope it will work doing a build,
arfoundition not working with webcamera on the pc right?

jade turret Jun 17, 2020, 9:01 AM

Yeah, can anyone help me in this error? I'm stuck with this error for a long time and I kinda needed a solution for this. I built the AR using AR Foundation with Image tracking, to which after I have built the game, once I went to the scene that involves AR, the App just crashes. This is the report that came after the crash. Is there a way to fix this kind of issue?

From what I have been discussed, it came from the library itself, stating that its performing a null exception specifically at the Image Target library. And after that, I don't know anything else. The setup was simple, which just involved a single Tracked Image Targeter on top of the usual things to run AR.

Any help is appreciated, and thanks in advance.

A logical question: i want that objects will be seen in AR in the moment I open the app. Does using a firebase datatbase and instating every peace of data from there through a loop is the right solution?(this is what i am currently doing)

I see multiple planes being detected how do I solve this?

jagged patio Jun 17, 2020, 4:34 PM

#

@shrewd rivet that's from the SDK and device itself, those should merge into one larger plane over time.

#

@vale lily the marker should be part of an reference image library. For scoring it you'll need to open the build project in XCode and inspect the image library there. For Android you can use the standalone ARCore SDK that scores images in the editor
