NAME
       gl_LocalInvocationIndex - contains the local linear index of work item currently being
       operated on by a compute shader


DECLARATION
       in uint gl_LocalInvocationIndex ;.SH "DESCRIPTION"

       In the compute language, gl_LocalInvocationIndex is a derived input variable containing
       the 1-dimensional linearized index of the work invocation within the work group that the
       current shader is executing on. The value of gl_LocalInvocationIndex is equal to
       gl_LocalInvocationID.z * gl_WorkGroupSize.x * gl_WorkGroupSize.y + gl_LocalInvocationID.y
       * gl_WorkGroupSize.x + gl_LocalInvocationID.x.
