Description

Data buffer to hold data for compute shaders.

ComputeShader programs often need arbitrary data to be read & written into memory buffers. ComputeBuffer class is exactly for that - you can create & fill them from script code, and use them in compute shaders or regular shaders.

Compute shaders need a fairly modern GPU (with shader model 5.0 support) and are at the moment available on DirectX 11, PS4, XboxOne and OpenGL ES 3.1. On shader side, ComputeBuffers map to StructuredBuffer<T> and RWStructuredBuffer<T> in HLSL.

See Also: SystemInfo.supportsComputeShaders, ComputeShader class, Shader.SetGlobalBuffer, Material.SetBuffer, Compute Shaders.

Variables

countNumber of elements in the buffer (Read Only).
strideSize of one element in the buffer (Read Only).
