Minimal Compute Shader Examples

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

Unity version : 2022.1+, contains both BuiltinRP and Universal RP (URP) scenes
See branches for older Unity versions
Tested with : Win DX11

Scene	Image	Description
`ComputeUAVTexture`		The most basic one, edit texture with compute shader
`AsyncGPUReadbackTex`		Similar to `ComputeUAVTexture`, but use AsyncGPUReadback to get texture data back to CPU
`ComputeUAVTexFlow`		Example of using compute to animate texture pixels
`ComputePaintTexture`		Paint the texture by sending object positions to compute shader
`ComputePaintTexture_DFT`		Similar to above but drawing with Epicycles using Discrete Fourier Transform. Ref to The Coding Train's youtube video
`StructuredBufferWithCompute`		Another basic one, use compute to calculate some data and send back to CPU
`AsyncGPUReadback`		Similar to `StructuredBufferWithCompute`, but use AsyncGPUReadback to get array data 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
`ComputeSketch`		Draw quads on the screen with color filled by compute shader
`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
`SkinnedMeshBuffer`		Blend the vertex data from 2 SkinnedMeshRenderer vertex buffer and render it with MeshRenderer
`SkinnedMeshBuffer_DiffMesh`		Similar to above but blending 2 different SkinnedMeshes. The blended triangles are drawn with DrawMeshInstancedIndirect()
`ComputeVertexLit`		A usecase of ComputeVertex so that different shader passes share same vertex data
`UAVInShader`		Read some data back to CPU from fragment shader
`AsyncGPUReadbackMesh`		It is much faster to update mesh vertices with compute + AsyncGPUReadback to get the vertex data back to CPU for physics
