NAME
       gl_GlobalInvocationID - contains the global index of work item currently being operated on by a compute
       shader


DECLARATION
       in uvec3 gl_GlobalInvocationID ;.SH "DESCRIPTION"

       In the compute language, gl_GlobalInvocationID is a derived input variable containing the n-dimensional
       index of the work invocation within the global work group that the current shader is executing on. The
       value of gl_GlobalInvocationID is equal to gl_WorkGroupID * gl_WorkGroupSize + gl_LocalInvocationID.
