Vulkan-ValidationLayers VS learn-wgpu

If this works then it might actually be a game bug and the game I guess passes invalid shaders when the cache exists... but it seems to work fine on windows vulkan drivers. You could try to run the game with https://github.com/KhronosGroup/Vulkan-ValidationLayers

For debugging these kinds of issues, I would recommend enabling the synchronization validation layer.

I would use the debugger to produce a stack trace and look into the validation layers source code. https://github.com/KhronosGroup/Vulkan-ValidationLayers Then I would either file an issue or make a PR there.

Currently validation layers might generate false-positive errors: https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/3450

A'rightey... I was able to reproduce this issue with Sascha Willems basic triangle example, so I am fairly certain, that this is a bug. I've opened an issue.

I am really at loss here, I found this issue but it doesn't really help me (I am starting to doubt it's even possible, maybe I'm a clown and doing it wrong...)

Can you post a reproduction case at https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues so we can take a look at it.

Which is why a GPU debugger with frame tracing is so much better option.

By the way, there are actually ways to expose a print function on shader code, provided there is driver support.

Huh yeah. Looking through the header the function you want works with c but there are others using c++ features. The reason given is understandable.

Nice.

Speaking of Snake game, if you want to go even deeper, you can try to use the wgpu crate to combine Rust and WebGPU to write everything from scratch. Here is the tutorial:

I once wrote a code editor with wgpu, from font rendering to char/line state management (very rough) for music live coding:

https://github.com/glicol/glicol-wgpu

It runs in browsers, even including Safari!

https://sotrh.github.io/learn-wgpu/ This is probably the best resource out there for learning wgpu specifically. If you're unfamiliar with graphics, the learnopengl one is good. If you've got experience though, jumping right into that one is a shout or looking at some vulkan ones as they're pretty similar in terms of architecture.

Most of The WGPU I learnt is from https://sotrh.github.io/learn-wgpu/ but it doesn't really talk about designing n stuff, I thought of checking out the source code for Bevy or even games like veloren. But well, their codebases are pretty big to get started in the first place.

So I was wondering if opting for option 1 would be better to begin with. OpenGL has a much bigger community and wgpu only has its documentation which I hear is not quite up there yet. There is this excellent tutorial for wgpu that I read through, but it seems like wgpu can be a lot more complicated than starting with OpenGL.

I started with wgpu tutorial (https://sotrh.github.io/learn-wgpu/) since I like the idea of portability and it's a Rust-first library, but it seems I'm missing some foundations of how CG works in general: the code is given, a little of explanation like it assumes I already know something, maybe I'm wrong, but I wish there was a longer explicit version.

If you haven't seen it: https://sotrh.github.io/learn-wgpu/ is a good introduction that will explain most of what you asked, then can refer to rend3d or bevys renderer to see how a render graph works.
