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).
