Lets Talk About Compute Shader 👾

[sDos280]

Hello my fellow raylibers👋, I opened this discussion to ask the community what it thinks about Compute Shader.
As you know, as programmers 👨‍💻 we always try to make our games faster, one way I could think about making my games(or simulations) run more quickly is by harnessing the powers of the GPU by using Compute Shader 🤖.

In the last weeks, I have been trying to learn about implementing Compute Shader in raylib but got stuck in most places mostly by the lack of information. so I thought of making a simple example for beginners about Compute Shader so more people will understand the benefits of using Compute Shaders.

I will like your opinion about the topic.

Shader language is a pain for me. Lots of mathmatics.

There should be some tutorial of raylib shader programming. There seems some default glsl shader variables, sometimes I hav no idea how they correspond to the C code.

[sDos280]

yeah, that right

[sDos280]

in some extent, shaders are usually used only for doing math operations in parallel

Don't use raylib - use godot. There are fully working compute shaders. Why do you need this raylib?

[sDos280]

Well, unlike godot rayib is a graphics library and not a game engine (which for me is easier to work with). I originally started this conversation to make a compute shader example for beginners so they may too use the power and the beauty of compute shaders...

You can use Godot for Compute Shaders only. Unlike raylib, Godot can use both OpenGl and Vulcan for compute shaders. :)

@sDos280 A compute shaders example was added some time ago: https://github.com/raysan5/raylib/blob/master/examples/others/rlgl_compute_shader.c

[sDos280]

Cool, I will check it out!

[sDos280]

Never mind, I thought this was another example (not the GOL example).

So yeah, I am aware of this example but (when I was a beginner) it was hard for me to understand it so when I understood compute shades much better i wanted to create a more simpler example to show the power of compute shaders...
