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).
