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