설명

Draws procedural geometry on the GPU.

DrawProceduralIndirect does a draw call on the GPU, without any vertex or index buffers. The amount of geometry to draw is read from a ComputeBuffer. Typical use case is generating an arbitrary amount of data from a ComputeShader and then rendering that, without requiring a readback to the CPU.

This is mainly useful on Shader Model 4.5 level hardware where shaders can read arbitrary data from ComputeBuffer buffers.

Buffer with arguments, bufferWithArgs, has to have four integer numbers at given argsOffset offset: vertex count per instance, instance count, start vertex location, and start instance location. This maps to Direct3D11 DrawInstancedIndirect and equivalent functions on other graphics APIs. On OpenGL versions before 4.2 and all OpenGL ES versions that support indirect draw, the last argument is reserved and therefore must be zero.

There's also similar functionality in CommandBuffers, see CommandBuffer.DrawProceduralIndirect.

This is mainly useful on Shader Model 4.5 level hardware where shaders can read arbitrary data from ComputeBuffer buffers.

Buffer with arguments, bufferWithArgs, has to have five integer numbers at given argsOffset offset: index count per instance, instance count, start index location, base vertex location, and start instance location. This maps to Direct3D11 DrawIndexedInstancedIndirect and equivalent functions on other graphics APIs. On OpenGL versions before 4.2 and all OpenGL ES versions that support indirect draw, the last argument is reserved and therefore must be zero.
