NAME

       gl_LocalInvocationID - contains the index of work item currently being operated on by a
       compute shader

DECLARATION

       in uvec3 gl_LocalInvocationID ;.SH "DESCRIPTION"

       In the compute language, gl_LocalInvocationID is an input variable containing the
       n-dimensional index of the local work invocation within the work group that the current
       shader is executing in. The possible values for this variable range across the local work
       group size, i.e., (0,0,0) to (gl_WorkGroupSize.x - 1, gl_WorkGroupSize.y - 1,
       gl_WorkGroupSize.z - 1).
