compute_shader_samples

This repository holds a list of samples to illustrate the usage of Compute Shaders for GPGPU (General Purpose GPU) tasks.

It includes samples for different platforms:

• OpenGL (with GLSL shaders)
• WebGPU (with WGSL shaders)

OpenGL samples

Name	Description
ssbo_sample	Sample that performs parallel operation on a vector of integers using Shader Storage Buffer Objects and workgroups
img_generation	Sample that generates a procedural image thanks to workgroups and ImageStore() method
convert2gray	Sample that converts a color image to a grayscale image using imageLoad/Store
boxblur	Sample that blurs an input image using box/mean blur algorithm and show usage of shared memory

WebGPU samples

Name	Description
buffer	Sample that performs parallel operation on a vector of integers using GPUBuffer objects for reading and writing data

Note: To make the examples run, WebGPU should be supported in your browser (see https://developer.mozilla.org/en-US/docs/Web/API/Navigator/gpu#browser_compatibility for compatibility)

Build OpenGL examples

$ cmake -Bbuild .
$ cmake --build build --target install

cmake installs all binaries and shaders into the install directory.

Usage

$ ./install/bin/ssbo_sample
...
$ ./install/bin/img_generation
