kernelIndex | Which kernel to execute. A single compute shader asset can have multiple kernel entry points. |
threadGroupsX | Number of work groups in the X dimension. |
threadGroupsY | Number of work groups in the Y dimension. |
threadGroupsZ | Number of work groups in the Z dimension. |
Execute a compute shader.
This functions "runs" the compute shader, launching the indicated number of compute shader thread groups
in the X, Y and Z dimensions. Within each work group, a number of shader invocations ("threads") are made. The work group
size is specified in the compute shader itself (using "numthreads" HLSL attribute), and the total amount of compute
shader invocations is thus group count multiplied by the thread group size.
Work group size can be queried using GetKernelThreadGroupSizes function.
