well I read the intro to the book and I'm now a game engine physics expert, nice
I'm surprised the only required math you have to know for the book is basic trig
I'm going to keep going with my fake physics camera controls atm, but I think I should read that book front to cover and build a custom physics engine
while I read it
in my project idk
I'm going to keep going with the game
it starts with a particle physics thing, and i want particles at some point
pseudo dock
When I lurk in the Physics Programming discord server the people there throw around all sorts of terms that I don't understand and so it seems like physics in modern games are much more complicated. But, yeah, the math in that book which I guess is more representative of physics in games 20 years ago is pretty accessible.
cloud rivet
idk I don't think classical physics have changed in the last 20 years though
so should be fine
pseudo dock
🙂
The "particles" it starts with just means that there is a single position and no rotations. So that's enough for my ball and bricks game, for example. But I guess you need rotation for your skimmers.
cloud rivet
it's probably like strength training, the human body hasn't changed much in the last 10,000 years, so I'm not sure there's like modern techniques that will do anything better than just picking up a barbell like they did 60 years ago
hrm
astral hinge
they have invented better steroids in the last 60 years
cloud rivet
my game needs rotations, I already have rotations, but it's all fake fake
steroids don't do much, it's such a meme
your average joe taking steroids and going to the gym will never get close to what elite body builders look like before they took steroids
cloud rivet
The "particles" it starts with just means that there is a single position and no...
maybe you want rotations if you want your bricks to ever fall
or explode or break into pieces or something
my camera actually doesn't need any physics anymore since I'm working on just putting it on a rail on the track
pseudo dock
I'm not sure that I completely agree with your premise. In the realm of graphics where I do know stuff the techniques have changed quite a bit over the last 20 years, and even though some of that change is just due to hardware getting faster so we that can afford to do stuff that we already knew how to do there is a lot of new techniques that have been discovered that make things better even though it doesn't fundamentally change the classic rendering equation from 1986.
I kind of imagine that physics is the same: It's not the fundamentals or the fundamental understanding that I predict has changed, but I bet there are lots of new techniques that have been figured out.
But, heh, it's hard enough for me to keep up with graphics so I'm just speculating.
cloud rivet
and I'll probably create the track such I get rid of those hard angles where the player's skimmer briefly disappears behind
that's fair
I kind of feel the same way about graphics techniques though in a lot of ways
ok with the exception of PBR I guess
pseudo dock
maybe you want rotations if you want your bricks to ever fall
Yeah... I really wanted to try and do all the physics myself just so that I could get actual experience doing it once, and that was really fun (and really rewarding). But if I ever decided to do something more complicated I think I would just use Jolt. The brick game was just something I decided to do that was feasible as a simple thing but it's not really my dream game or anything, so I don't think I'll expand the physics much. (Well, with one exception: There are lots of animations I have with just constant velocity that I wish had acceleration so I will maybe revisit that one day, but for the actual simulation with collision detection and response I think what I have is probably good enough for me heh.)
cloud rivet
if I made a game that looks as nice games looked and felt like a game from 20 years ago, you know like Oblivion, Battlefield 3, etc I'd be stoked. although I realize that those had massive budgets and people working on them
pseudo dock
It's hard to believe, but it's actually approaching 20 years since I got my first job in the games industry (and doing graphics)! 👴
It's funny/sad reading people in this server talk about games from that time like they're ancient and I think "wait.... are they?" lol
cloud rivet
yeah
a coworker asked me not too long ago while talking about Nirvana if I ever heard of Soundgarden
pseudo dock
haha
cloud rivet
I was floored, like what, of course I have, they were all over the radio and MTV in...oh right, early 1990s
so you work in the industry?
you shipped some titles?
pseudo dock
I actually do again, as of 3 weeks ago! But I was out for about 10 years, although kind of adjacent.
cloud rivet
nice
I wonder what people who work on this for a living think about this server sometimes, although I know a number of people on here do work in it
pseudo dock
Oh, yeah. Umm, let's see:
Bolt, Toy Story 3, Cars 2, Disney Infinity 1, 2, and 3
(I worked for Disney at Avalanche Software, but after Disney shut us down I decided to try something else rather than stay when it was resurrected by Warner Bros)
pseudo dock
Games, based on the movies (except for Disney Infinity)
pseudo dock
Haha it doesn't seem like it, but I guess so. Look, it's me talking about it at SIGGRAPH 2010: https://advances.realtimerendering.com/s2010/index.html
cloud rivet
what could I tell anyone they don't already know
I mentor jr engineers
I know enough to do that I guess
astral hinge
what could I tell anyone they don't already know
you'd be surprised
the curse is that things you already know seem obvious
cloud rivet
hrm my camera idea of following a rail on the track falls apart when the skimmer turns around and goes the wrong way now that I think about it
that's a problem with the physics too, there's collision problem when the vehicle goes reverse up an incline it goes through the track, because the math currently assumes a one way direction
it's dumb
I'll make it work in one direction and then fix it, it doesn't work at all right now
pseudo dock
Is your intent to allow the skimmer to go the wrong way and in reverse?
pseudo dock
I guess I was wondering whether you would like to prevent it from happening but just don't have code yet to do that, or whether you ultimately would like to allow it
cloud rivet
you can go in reverse yes
well I think being able to go in reverse is ok in case you get stuck and need to do a turn about or something, and in that case I need to be able to handle it generally I think, even if I put some kind of block in place for traveling in the reverse direction
pseudo dock
Hmm, yeah, that makes sense
cloud rivet
I'm not going to worry about it right now though, since it is a bit of an edge case
but it's just highlighting how fake my physics are
well they are
pseudo dock
Doesn't matter if it works for the game and is fun 🙂
cloud rivet
true!
true moon
https://xkcd.com/2501/
My favorite xkcd of all time lol
cloud rivet
it's pretty good
ok my first attempt at the on the rails camera will be just apply the player's forward velocity also to the camera, but the camera is just oriented by using the forward, up, and side vectors of the current track it's over, and it's just hovering over the current track by some scalar value up the track point's normal
solid grove
when you add lap checkpoints you'll know if the skimmer is going the wrong way
cloud rivet
yeah
solid grove
because the next checkpoint it hits will be smaller
cloud rivet
the track points all have curveu values which range from 0 to 1
they're generated by houdini
When the Curve U checkbox is on, create an attribute on the generated point(s) containing the fractional position (between 0 and 1) along the curve where the point was found. For example, if the point was extracted from one-third of the way along the curve, the node would set this attribute to 0.33 on the point. The default attribute name is curveu.
The main purpose of this node is to extract a ballistic projectile’s position at a given time. However, it can also be used to extract points from many curves in custom patterns for abstract effects.
houdini is so cool
I just think this isn't going to work, but I can't be paralyzed by not knowing what to do, so I just need to do something and figure out how to fix it if it is broken
this is like 4th or 5th attempt at a third party camera 😅
cloud rivet
the most important thing I need right now is a good look at method
I'm going to work on that this weekend

solid grove
the most important thing I need right now is a good look at method
Highly recommend you add a transform hierarchy. It makes so many things (like cameras) easier
solid grove
my camera is made of 3 transforms
i can animate and position the pieces independently and the engine takes care of all the space translations
cloud rivet
yeah that makes sense
I'm having a fundamental math ignorance issue with this, that I just need to resolve once and for all, is part of the plan, like given two points find a way to orient one thing so it is pointing in the direction of the other
solid grove
my karts are also made of nested transforms as well. The kart itself is made of two (the rigid body and the car model), then the player doll is on top of that, and objects are attached to the player’s hands
cloud rivet
that makes sense
I just shouldn't be struggling with this problem, I am going to like do it with pen and paper if I have to
solid grove
when you drive into the TNT it makes itself a subject of the player doll’s head
cloud rivet
if I had things in the world I could parent that would make sense for me, it definitely makes sense for you

hrm time to build my look at function
it'll accept my project's location type, a position of the thing to look at and return a quad and I should be able to have any object that has that location type orient itself to look at that position. I will set up a little debug UI for it first
solid grove
it'll accept my project's location type, a position of the thing to look at and ...
I will set up a little debug UI for it first
ah, i see your development workflow is the eact opposite of mine
cloud rivet
no actually
I have written a couple of look ats and they all fail in the same way
so this is like attempt # 5 or something
but going to do it intentionally and with tooling
there must be something fucked about my coordinate space that I hadn't encountered yet since I haven't written any gltf scene loading code, just these basic meshes
although everything seems correct and I haven't written any weird coordinate/perspective code, my track looks correct, my camera moves around correctly
it's super weird
anyway I'm getting to the bottom of it
probably a math code bug
cloud rivet
I've somehow managed to crash renderdoc
wraith urchin
Classic
cloud rivet
just crashes on trying to load a capture
hrmmm
let me try nsight I guess
nsight is fine
must RT related
wraith urchin
I find Nsight alot more usable IMO
cloud rivet
than renderdoc? wow
wraith urchin
I dunno it just seems easier to find the event I'm looking for in Nsight
I only use renderdoc if I'm on AMD or Intel
cloud rivet
I find there anything like the mesh viewer in renderdoc in nsight?
wraith urchin
Nsight 100% has a mesh viewer, I use it all the time
tight torrent
must RT related
yeah renderdoc really doesnt like rt
PIX is the one i like the most for RT debugging, but thats dx12 only
wraith urchin
I will say renderdoc does let you look at the verts post-transform, which nsight does not
cloud rivet
yes that's what I want to look at right now
haha, I was looking for my cube I wanted to put at the origin and couldn't find it
it was hiding
apprently I have a bug where I applied my skimmer transform to all meshes
wraith urchin
Wait this game is using RT?
cloud rivet
just for shadows
wraith urchin
Ah
cloud rivet
I bet this is actually UB
and this is why renderdoc is crashing
btw ray tracing shadows took so much less effort and heartache than a CSM
and it looks better too
100% worth it
tight torrent
btw ray tracing shadows took so much less effort and heartache than a CSM
yeah rt shadows are dead simple compared to like literally anything else
cloud rivet
first thing that vulkan has ever done for me that has made it almost worth using
solid grove
they become a little less simple when you want to support arbitrary materials. i'm still working through how I want to generate those
solid grove
yeah it seems like a requirement
the API gives you the user-defined ID, and then you have to use that to look up all the object data
cloud rivet
why do your shadows need materials?
cloud rivet
I am going to actually add reflection and emmissive
yeah
I will need materials eventually
solid grove
cutout transparency was free with CSM
cloud rivet
I don't know of a need for cutout for me
solid grove
colored shadows wouldn't've been too difficult with CSM, just kind of inefficeint
cloud rivet
what's the thing you have that's transparent?
solid grove
it works but it doesn't give me info about my ray tracing stuff so it's not that useful to me
cloud rivet
I'm doing something to crash it and I'm sure I have a bug somewhere since I a second mesh for the first time in this game
nfi what it is
solid grove
gpu-driven validation?
solid grove
if you're using vulkan you have to use validation
cloud rivet
yeah I use that
VVLs
I am not getting any validation errors
hrm
let me turn on verbose errors
nope, no validation errors
outside of the ones slang generates
solid grove
they changed the UI but there is a setting in vulkan configurator that lets you eanble gpu-driven validation, which adds extra code to your shaders to detect things like out-of-bounds memory access or use of unbound descriptors
cloud rivet
but those are slang bugs
solid grove
you can also try using Nvidia Aftermath if you have an nvidia gpu, it will tell you what shader caused the crash and what kind of crash it was
cloud rivet
nvidia doesn't crash, just renderdoc
I'll try aftermath
nvidia nsight graphics I mean
solid grove
eg this one tells me I have a nullptr dereference
cloud rivet
I'll try aftermath though
oh ok I'll try gpu validation I haven't heard of that before
nada
just the slang VVLs
which don't break anything and have been there since forever
solid grove
other option would be to compile a debug build of renderdoc and see what's causing it to crash
solid grove
but you'd get whatever exception or assertion is triggering in renderdoc
cloud rivet
I will try aftermath
solid grove
which could give you a clue about what you're doing
cloud rivet
true
cloud rivet
oh I just updated nsight to the 2025 version and it is much better
aha
it is RT
I just started commenting out code until it stopped crashing
going to just disable RT for renderdoc since it can't debug it anyways
cloud rivet
nice ezpz
now I have renderdoc support
and
I just have actual conditional RT now
hrm but I still use the rayquery in the shader
idk
whatever
renderdoc not wanting to be a RT debugger means it kinda doesn't want to be a graphics debugger
I'd have to have a non RT shader just to support renderdoc to make this work end to end
I don't get any VVLs for my RT stuff, and nsight works
tight torrent
going to just disable RT for renderdoc since it can't debug it anyways
Yeah kinda stupid they wont support it imo
It sorta does, it'll play back rt calls
Just not let you inspect them the same way as raster? Idk I've never used renderdoc with rt
cloud rivet
it just crashes renderdoc for me
all I did was add a second blas and instance
and now it crashes
works fine without renderdoc and in nsight
cool, multiple meshes now
something's fucky why is the cube changing colors
oh I know
fixed
also figured out how to record just the game instead of my whole screen
man that was a lot of work just to add a cube
I made it easier to add any amount of meshes though
pseudo dock
something's fucky <:KEKW:666849321462792234> why is the cube changing colors
The skimmer reminds me of a cute li'l headcrab in this video, with the debug lines looking like little legs and it hopping around like a headcrab 😂🧡

I just made a box lol
I am trying really hard to stay focused on making progress on my goals and am resiting the urge to just write a full physics engine by following the book. I need to wait until I have some amount of something that looks like an actual game before I get side tracked into a rabbit hole that big
the big rabbit holes are the full physics engine and textures, and they're all months long projects
cloud rivet
the other big one is gltf
bronze socket
everything is so simple and straightforward and then it explodes
gltfs don't explode
cloud rivet
it's just a lot of work to NIH these
if I were to estimate, I could divide a year into quraters, the gltf and physics would take two (one each), and textures would take 2
I think textures would be more work because it's 3 formats I want and then the transcoding to basis
hushed creek
nooo dont write a gltf parser
cloud rivet
if I don't I can't have gltf
hushed creek

I luckily haven't had much trouble with bindless, you could probably enable the null descriptor option and you might at least get a visual of where it's happening
solid grove
what is the null descriptor option?
bronze socket
one of the feature settings for bindless that makes null descriptors in your array valid, iirc it has a performance penalty so you don't want it, but you'll at least just get black samples instead of crashing
solid grove
interesting
solid grove
really wish it would capture info about the thread that caused the crash so I can debug it
but all you get is an address rounded to the nearest 4K
and the shader program
sometimes it gives you an IL reference in the shader but it’s pretty inaccurate
astral hinge
I write a null descriptor to the slot when freeing a descriptor
using the thingy domeboy linked
bronze socket
I don't use null descriptor but I think I use partially bound which is okay with things being null so long as you don't access them
cloud rivet
when freeing a descriptor 
bronze socket
it's possible for my descriptor set to hold refs to dead images but its no big deal
astral hinge
when freeing a descriptor <:thinkeyes:583790830163066880>
I manage bindless descriptors with an index allocator
bronze socket
you don't need nullDescriptor then so long as you have partially_bound_bit, faster too since you don't get the checking
for me "freeing" is just recycling the index so anotehr image can write into it
to keep the fragmenting down
astral hinge
but I never free them
I use it a lot for transient buffers and resources that are tied to the output size
bronze socket
busted
astral hinge
I mix bda and buffer descriptors at random
bronze socket
I actually do that too tbh, my transient descriptor set allocation is too convenient for mocking things up
usually I convert things to BDA closer to when I finalize them
astral hinge
I have a crash that's caused by using bda though
a crash in glslang when it tries compiling my shaders
bronze socket
I've had a crash before where spirv-reflect just didn't consider I could get certain instructions in a certain order so I had to PR them a 2 line fix
solid grove
Glslang’s #include doesn’t work
if you have certain kinds of path
I fixed it for myself in my own checkout since I’m doing something a little weird
bronze socket
I think I switched to glslc because I couldn't manage to get glslang to take additional header search args
solid grove
does glslc not just use glslang?
bronze socket
99% sure it does but the glslc CLI is somehow better than using glslang directly
astral hinge
the cli binary from the sdk is built in release mode which means it doesn't have the checks that make it crash for me 
astral hinge
does glslc not just use glslang?
it does. I've had to look at the source code to figure out how to do certain things like enable debug symbols
and stuff like the option that prepends text to your shader literally builds a string that gets prepended to your loaded file before it's sent to glslang
cloud rivet
ok, now I can start working on the orientation code
so I'm going to use that as my third party camera placeholder when I'm not in third party camera view
so I'll just start with the rotation around the y axis assuming a world up, then I'll add pitch, and then make it work with the track normals, and then have it follow the skimmer and then it should just work?
and then I'll just make that a generic look at function that just works with whatever
broken fog
ok, now I can start working on the orientation code
i can't unsee the headcrab now
cloud rivet
I may move up wavefront obj file parsing on my timeline 😅
broken fog
then you can import an actual headcrab

when I originally played hl2 I didn't think they were cute, they scared me
but I guess they are cute now
broken fog
they just want to cuddle
bronze socket
how does sorse store skeletons
oh wait source games have weird file formats nvm, that made me think they used obj for a moment
cloud rivet
there's the bug
ok
a sign issue I think
I had this problem in my last project too I remember now
I think I
astral hinge
the z fighting of the yellow and red lines makes it look like a cute walking animation
cloud rivet
animation ✅
nice, one thing I don't need to worry about now
going to write that angle to the ui
yeah it never goes negative
cloud rivet
auto cross_p = cross(world_forward, v_projection_to_xz);
auto sign = dot3(cross_p, world_up);
auto dot_p = dot3(v_projection_to_xz, world_forward);
auto angle = acosf(dot_p);
if (sign < 0.f) {
angle = -angle;
}
cool cool
hrm
ok now to get the other angle
the pitch as it were
cloud rivet
had a huge bug
my quaternion form is w, x, y, z and my mat to q did x,y,z,w :(
that was the bug
a normal look at function now works
no issues with my coordinate system thank god
astral hinge
one time glm updated and changed the quat constructor from xyzw to wxyz. that was fun to track down
cloud rivet
this wasn't fun at all
like my approach at one angle at a time ran into gimbal issues
astral hinge
are you reinterpreting your quat struct as an array of float or something
If you accessed the fields one at a time I can't see how you'd get this bug
astral hinge
I'm confused how the storage order mattered here
astral hinge
"ideally" the user of the quat wouldn't need to know whether it's xyzw or wxyz
oh I think I see
the math was just wrong?
cloud rivet
right because it made the quaternions incorrectly
because I copied it out of my math book
astral hinge
I think I was projecting my storage bug onto you
cloud rivet
I mean I understand what it does
I understand what the trace of a matrix is
and how the construction of the quaternion works vi athe math
I just wrote the w to the w variable, and then the clang vectors have a w data member
it just happens to be the wrong one
astral hinge

what's the origin story for your pfp?
it looks like gumby, I keep thinking is like a gumby like character
I think my brain stopped working and I can't do more right now
why does that happen

what's the origin story for your pfp?
my pfp used to just be this guy, but then someone on another discord made a few edits, including the current one

ok next thing is to add more velocity attenuation when jumping I think,
also keep forward momentum when not giving power so you can't break midair
broken fog
ok next thing is to add more velocity attenuation when jumping I think,
that's a huge jump
ngl it looks super fun
if you tone it down maybe you can have like a moon level where jumping just yeets you way up
solid grove
might want to have the gravity increase after a certain amount of time in the air
can help the skimmer feel more substantial

I finally started using lsp renaming in neovim, it works so great
yesterday I spent a lot of time manually prefixing my C functions and today I decied to see how good the lsp rename works and it works amazingly
just no undo
git reset is the undo
oh maybe there's an lsp undo
no there's not
brisk chasm
as a neovim bro, you need a split keyboard too
cloud rivet
I don't like those
brisk chasm
: )
cloud rivet
I have a normal logitech keyboard like a regular person
brisk chasm
yeah
i was just joking
those split-keyboard-yt-bros, who keep typing a word once then backspacing 100 times before writing one more word correctly
cloud rivet
the biggest drawback to neovim is really tracking global changes/sessions, it's all just buffer based
if you have some plugin or something that changes files that aren't even open there's no hope
brisk chasm
jetbrains' tools have a local version thing, where it kind of snapshots your code in various intervals, and you can go back in time when needed, and you have not setup git or havent commited in a while, its pretty handy
cloud rivet
and most commands just work on the current buffer
yeah local version in jetbrains has saved me so many times
brisk chasm
same hehe
cloud rivet
visual studio has this too with the resharper C++
brisk chasm
yeah
cloud rivet
hrm
brisk chasm
i always wanted to give neovim a true and honest try for more than just 2mins, but i cant
im too stupid to start memorizing all the vim keybinds, or perhaps too old, idk
cloud rivet
it's impossible to memorize
the way to do it is to just start with the basics
build up muscle memory
brisk chasm
yeah
brisk chasm
i keep going back to clion
cloud rivet
it's just my fingers doing stuff
brisk chasm
i owuldnt even know what to do really, when editing text "ok here i need to go to the 5th word on that line to put an a in between 4 letters of that word"
so i just go into i, and cursor there and just put the a 🙂
and not do 5w and i and whatever else vim bind you press before i
cloud rivet
I used vim from like 2005 to 2012
and then gave up when multi cursor came out and used jetbrains IDEs for about 5 years
and then at my current job all our work is remote
brisk chasm
yeah alt+shift+. is ❤️
brisk chasm
ah vscode is great there
cloud rivet
but now I'm back to neovim since june
well new to neovim
I hadn't ever used neovim
brisk chasm
aye, so you went through the valley of pain already
cloud rivet
yeah
brisk chasm
and learned ze basics
cloud rivet
neovim is much better than vim, I would never use vim
well I have been using vim for commit messages and cli stuff, I never stopped using it
for small edits
but as a main editor
no thanks
brisk chasm
i use it for config files too, but its just cursor keys and no vim motions or whatever, dd and u at maximum heh
cloud rivet
now I am using Neovide, which is a UI for neovim
all it does is uh fix the cntrl key and adds fancy cursor animations
and smooth scrolling
one of the problems using neovim or any editor in a shell is that shells don't like control key
brisk chasm
yeah i heard of neovide
cloud rivet
what are you using?
clion?
I still have this installed, I don't think I've opened it in years
brisk chasm
ye clion and sometimes vscode
cloud rivet
3 years
brisk chasm
😄
cloud rivet
I have been paying the license all this time
cloud rivet
yeah
brisk chasm
i have that one too, i think its worth it
if i was using vim or any other vimlike i would probably quit jetbrains too
cloud rivet
oh shit, I have work code on this computer, the last thing I opened in this project is from my job
😅
that's gotta go

neovim is much better than vim, I would never use vim
i have a vim conf but never touch it lol
it has nertree, clangd plugin and thats about it
tried nvim once, didnt feel like it
cloud rivet
I tried running neovim on my 32GB of memory dev machine and it ooms
so I still use vim on that thing
brisk chasm
ah thanks for reminding me
tight torrent
how lol
cloud rivet
it's actually gopls that ooms
brisk chasm
i noticed this laptop swapping despite having 19GB free ram out of 32gb
cloud rivet
the go lsp
but it kills neovim
what's weird is that visual studio code's client that runs on the same machine also uses gopls and it doesn't die, but gopls does sometimes have problems
brisk chasm

going to just uninstall intellij and finally cancel my license I think

ohh my jetbrains annual license fee is really cheap though
holy shit
it costs double what I pay
haha
brisk chasm
it usually goes down every year, for 3 years and then you keep paying that lowest
brisk chasm
yeah same
cloud rivet
that's a big incentive to just keep paying the money
I'll just keep it lol
they got me
let me see what they got maybe I like something
brisk chasm
they do provide good software 🙂
i frequently use rider, clion, webstorm and datagrip

ohh my jetbrains annual license fee is really cheap though
whats neat is a license is perpetual, the annual/monthly part is for updates

I'm going to try fleet
can't parse my C
I'm going to try and replace my notepad++ usage with fleet
it should have just been able to parse my C with clangd and compile_commands.json
I dont' think this editor can replace notepad++, it's a bit slow
tight torrent
i personally use kate + kdevelop for a text editor + ide
brisk chasm
wouldnt surprise me if they retire fleet again
brisk chasm
luckily a lot editors can do that
silver slate
Most of the ones I know require me to press two keys for that and they may overlap with another combo and then my first select isn't a column select and then the second one is but I have then already closed the program and started cursing about it in a random Discord chat.
astral hinge
I can hold alt, ctrl, then press arrow keys to select multiple lines
brisk chasm
alt + left mouse works for me for the ones i know
yeah and that, what jaker said, i also very much like alt+shift+. in jetbrains' tools, multi select on whatever is at the cursor/isselected
astral hinge
maybe it was alt+shift in visual studio too, my fingers just do it
brisk chasm
depends on the keyboard schkeeme probably
tight torrent
alt + ctrl is what works in vs code
ive used it alot more than i expected to when i first figured it out lol
brisk chasm
vscode default keymap is botched when you are used to vs/resharper/jetbrains-keymaps heh
ctrl+- in vscode doesnt navigate back, it zooms the ui out 😄
hushed creek
I hate that so much
especially since I never want code zoom in/zoom out, I set a font size when I install the IDE and that's it
cloud rivet
I zoom in all the time because my vision went bad as I got older
I was going to make some progress and instead renamed almost everything
everything is now snake cased and prefixed with p_
I was pretty excited to use camel case when I started this project because resharper in C++ forced me to snake case and I wanted camel case, but over time I just ended up preferring snake case in C
it's beause I think I don't have any types, just functions and structs
types as Type types
cloud rivet
fleet is terrible
I'm going to cancel my jetbrains license I don't want any of these editors
it expires soon so good timing
cloud rivet
kinda have to avoid launching yourself off a ramp now to keep your speed going
kind of fun
pseudo dock
What's the technique to avoid launching yourself off a ramp?
cloud rivet
slowing down so you're not accelerating off into the air too high
the two shoulder triggers are analog
left applies reverse thrust and right applies forward thrust
this track is kind of silly, since it has such hard edges
I'm going to smooth it out and there will only be ramps in interesting places
I really have no idea what I'm doing
I actually want to replace the soap bar/roach thing
I'm going to see how much my maya skills have deteriorated in the last 5 months
there's ton more track/physics work to do obviousily
but I want to add a wavefront obj parser and then actually replace the blue background with a ray traced scene
pseudo dock
Nice
astral hinge
your game is looking fun already
cloud rivet
I think I will try out VK_NV_cluster_acceleration_structure
for the background
astral hinge
the race track will be a shrimple quad ribbon but the background will be a hyperrealistic path traced scene with a billion triangles
cloud rivet
I just want a height map
solid grove
my simple test track is over a million triangles 
cloud rivet
idk
astral hinge
imo that extension seems geared towards very complex scenes, but nothing is stopping you from exploring it for fun
cloud rivet
yes I just want tessallation geometry in the RT pipeline
astral hinge
I think there might be special intersection methods that are extra fast for heightmap
cloud rivet
oh that's cool
cloud rivet
I'll check that out first thanks
astral hinge
and you could use an intersection shader to trace it
brief googling gave me this
https://publications.lib.chalmers.se/records/fulltext/250170/250170.pdf
oh I replied to the wrong thing
astral hinge
I think there might be special intersection methods that are extra fast for heig...
I meant to reply to this
astral hinge
I'd remove the vulkan keyword personally
cloud rivet
thanks for your help I'll look at using an intersection shader
I'll make a better skimmer model and add an obj parser before that and then I'll look at making something better than a blue background

the hiring process is remote unless you're near by
we're in portland and san francisco

yes
hiring process is talk to one of our recruiters, there's a phone screen and about 4 panels in one day, one of which is technical

oh I see, try applying! good luck!
I don't like have any influence over the process, I'm just a cog
tawdry pewter
np.
just to be clear, there are three open roles as software engineer.
which role should I apply?
cloud rivet
read through them and find one that's good for you
tawdry pewter
hmm, okay.
brisk chasm
kind of goes without saying that you need to pick what you want
bronze socket
normally not reading the JD would have you insta filtered
even before AI when you'd be instafiltered anyway
cloud rivet
I have no idea what the team that reads the application does
I just get an interview scheduled and then I enter feedback and then someone makes a decision and I have no influence or understanding of it
when it was just a few of us five years ago, we didn't even interview
it's all been enterprisified
it's kind of weird to being just a few people, where the "CEO" is just a title one of the other people on the team had and we all worked together, to now I'm a line engineer and the CEO is flying around the world meeting other CEOs and I barely ever see them anymore
bronze socket
are you at least sitting on enough options to be happy
tawdry pewter
yeah I have equity, but I think it's all weird in a cool way
how many developers are there in the company now?
cloud rivet
I don't even know anymore tbh
there are lot of teams now
there are many more teams of engineers now then there used to be engineers
probably want to ask when you talk to someone
cloud rivet
idk, by default I don't count equity as worth anything, even though I did exercise a year ago and that was really expensive
but I just assume it is worth nothing, because 9 out of 10 times that's how it turns out
this is like my fifth or sixth startup

obj doesn't support vertex colors fml
according to an ancient stackoverflow post (https://gamedev.stackexchange.com/questions/21303/how-can-i-include-vertex-color-information-in-obj-files), autodesk meshmixer puts the colors immediately after the vertex definition
ex a vertex at 1, 1, 1, with a color of 1, 0.5, 0 would look like
v 1 1 1 1 0.5 0
or something

yes I think that's what the blender extension does too
I think the python script to do this would be easiest

I shall have a proper skimmer tomorrow or the next day
and then I'll probably be doing ray tracing stuff for a couple of months
the goal with RT is to just draw the background world with it, I will use the graphics pipeline for the geometry around the track, like if it goes into tunnels or through buildings or anything that will be rasterized, I just want the like distant world to be RT, that's it
and I'll use RT for shadows, and GI and reflections I guess, idk
I don't want to RT the game's geometry because I don't like the noise
and I just want a graphics pipeline
idk
solid grove
will the backgrounds be animated?
cloud rivet
I hope so
hrm the scale of this vehicle is huge tbh
12 meters :X
14 actually
I'll make the track bigger
or shrink it
14 meters is ridiculous
i'm going to import in blender to see what it looks like
idk how to even rotate in blender
looks kind of dumb
I'll keep working on it later
I should bevel the edges
anyway I'll make a skimmer customization feature, so it's fine

Scroll wheel click + drag rotates camera iirc

I actually figured it out: alt+F4

Blender has a LOT of controls

Eh you get through them pretty fast

I should stop using slang since I can't understand the words used in the documentation
Slang supports the DescriptorHandle<T> type that represents a bindless handle to a resource. This feature provides a portable way of implementing the bindless resource idiom. When targeting HLSL, GLSL and SPIRV where descriptor types (e.g. textures, samplers and buffers) are opaque handles, DescriptorHandle<T> will translate into a uint2 so it can be defined in any memory location. The underlying uint2 value is treated as an index to access the global descriptor heap or resource array in order to obtain the actual resource handle. On targets with where resource handles are not opaque handles, DescriptorHandle<T> maps to T and will have the same size and alignment defined by the target.
slang is a black box and when it doesn't work I just feel helpless
there's no spec to refer to
I think the VVL support for the RT pipeline is largely insufficient
astral hinge
I think you're supposed to ask on their discord or github
cloud rivet
I have no idea why renderdoc crashes still on opening up captures
cloud rivet
I think you're supposed to ask on their discord or github
this is horrible
also I did ask
astral hinge
indeed, having an actual spec would be miles better
cloud rivet
and it hasn't helped
I hate asking for help. I did today
and what was offered didn't work
astral hinge
only now did I realize that glsl does have a big advantage over other shading languages, and it's that it has an actual comprehensive spec
cloud rivet
yeah
I get VVLs about layout issues for my acceleration structures in my slang, I am using descriptor indexing which is actually not officially supported by slang, but just seems to work anyway
ACCELERATION_STRUCTURE is excluded from the list of types since Slang by default uses the handle to a RaytracingAccelerationStructure as a GPU address, casting the handle to a RaytracingAccelerationStructure. This removes the need for a binding-slot of RaytracingAccelerationStructure.
you search for anything related to RaytracingAccelerationStructure on the slang discord everyone is using the device address you get from vkGetAccelerationStructureDeviceAddressKHR
tight torrent
> Slang supports the DescriptorHandle<T> type that represents a bindless handle ...
ok so descriptorhandle effectively acts as resourcedescriptorheap[index] where the descriptorhandle is index, unless its not targeting hlsl glsl spirv in which case its T?
cloud rivet
I don't know how T is useful here since bindless requires a descriptor set and index right
you need two numbers
how do I supply two numbers if it's just "T"
and the answer just seems to be not to use descriptor indexing with RaytracingAccelerationStructure, but that's the only thing that works for me, I would love to have a small C++ example demonstration of this like one of Sascha's examples but can't find anything like it
hrm
tight torrent
how do I supply two numbers if it's just "T"
well its a uint2 if im reading the docs you pasted right?
cloud rivet
in the case of a device address the uint2 is a 64bit address
hrm
I gotta ditch slang I hate it
tight torrent
its built to be a 1:1 mapping of hlsl, or very close to it
maybe its simple to switch to dxc -> spirv comp?
astral hinge
it's a superset of pre-2021 hlsl
Bjorn is trying to use one of the new (slang-only) features
astral hinge
hlsl doesn't have the magic descriptor handle thing you're trying to use
it supports bindless but in a different way
cloud rivet
what's interesting is that's so simple in spirv
it's just trivial to follow it in spirv
^^ this slang won't even load for me by the way, compiles fine in godot, I get VVL errors for it
It compiles fine
but when I load the generated spirv VVLs
it's fine
skill issue or something I don't know I was going to work on obj parsing but just got tired of the RT vvls
I'm going to pause working on the game and focus on trying to target spirv directly
fuck it

@cloud rivet if you need some more 1:1 help to get things fixed, just ping me
😅 I feel a bit bad regarding everything not working for this stuff
cloud rivet
😅 I feel a bit bad regarding everything not working for this stuff
I appreciate your help 
I just don't like slang I think
silk pier
fair enough--
if I may ask (it'll help me to know), what don't you like about Slang?
cloud rivet
I love pointers
I don't mind generics in theory, but it seems once you have generics the type syntax can become incredibly complex and unfun to read and think about for me
which is fine for work that I get paid for
but for a personal project I don't think it's for me
silk pier
mmm
well, if you want c or almost-c to spirv, there should be a few options
or at least, they have code you can reference when you make your own
silk pier
this little maneuver's gonna cost us 51 years
the making a new c->spirv compiler?
probably better to contribute to an existing one to be fair
cloud rivet
the making a new c->spirv compiler?
You go above and beyond. Thank you for your help. You’re excellent. 
I will look at all these!
I think that vcc one looks interesting
nano made their own c to spirv wow
cloud rivet
I'm looking at this actually https://github.com/google/spirv-tutor/tree/main/01 - Introduction to SPIR-V
so what I think I'll do is write some tests, and just start with a single triangle
once I'm past the spirv tutor I guess
