gl_WorkGroupID — contains the index of the workgroup currently being operated on by a compute shader
in uvec3 gl_WorkGroupID
In the compute language, gl_WorkGroupID
contains the 3-dimensional index of the global work group
that the current compute shader invocation is executing within. The possible values range
across the parameters passed into glDispatchCompute
, i.e., from (0, 0, 0) to
(gl_NumWorkGroups.x
- 1, gl_NumWorkGroups.y
- 1, gl_NumWorkGroups.z
- 1).
