NAME

       gl_WorkGroupID - contains the index of the workgroup currently being operated on by a
       compute shader

DECLARATION

       in uvec3 gl_WorkGroupID ;.SH "DESCRIPTION"

       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).
