Minimal Compute Shader Examples

Minimal test scenes contains compute shaders, compute buffers etc Playing with the transport between CPU <-> GPU

Unity version : 2019.3+, but should work in older versions as well
Tested with : Win DX11, Mac Metal

Master is BuiltinRP. Please checkout UniversalRP branch for URP.

Scene	Image	Description
ComputeUAVTexture		The most basic one, edit texture with compute shader
ComputeUAVTexFlow		Example of using compute to animate texture pixels
StructuredBufferWithCompute		Another basic one, use compute to calculate some data and send back to CPU
StructuredBufferNoCompute		ComputeBuffer doesn't always need to stick with ComputeShader
IndirectCompute		Simple indirect compute (indirect dispatch) and CopyCount
IndirectReflectedStar		Draw stars on the screen only if the pixels are bright enough
ComputeParticlesDirect		GPU Particle, drawing fixed no. of particles
ComputeParticlesIndirect		GPU Particle, drawing dynamic no. of particles, no need to read back to CPU!
ComputeVertex		Replace vertex buffer with StructuredBuffer and drive vertex displacement by compute
ComputeVertexLit		A usecase of ComputeVertex so that different shader passes share same vertex data
UAVInShader		Read some data back to CPU from fragment shader
AsyncGPUReadback		Similar to StructuredBufferWithCompute, but use AsyncGPUReadback to get array data back to CPU
AsyncGPUReadbackTex		Similar to ComputeUAVTexture, but use AsyncGPUReadback to get texture data back to CPU
AsyncGPUReadbackMesh		It is much faster to update mesh vertices with compute + AsyncGPUReadback to get the vertex data back to CPU for physics

Disclaimer: The stuff here might not be the best practice / optimized :'(. But at least they works. Play them for fun.
