SDL_DispatchGPUCompute3
Dispatches compute work.
Usage
#include "SDL3/SDL.h"
void SDL_DispatchGPUCompute( SDL_GPUComputePass *compute_pass, Uint32 groupcount_x, Uint32 groupcount_y, Uint32 groupcount_z);
Header file
Defined in SDL3/SDL_gpu.h
Overview
You must not call this function before binding a compute pipeline.
A VERY IMPORTANT NOTE If you dispatch multiple times in a compute pass, and the dispatches write to the same resource region as each other, there is no guarantee of which order the writes will occur. If the write order matters, you MUST end the compute pass and begin another one.
Function parameters
compute_pass
|
a compute pass handle. |
|---|---|
groupcount_x

number of local workgroups to dispatch in the X dimension. |
groupcount_y
|
number of local workgroups to dispatch in the Y dimension. |
groupcount_z
|
number of local workgroups to dispatch in the Z dimension. |
