%mathent; ]> 2011-2014 Khronos Group gl_WorkGroupID 3G gl_WorkGroupID contains the index of the workgroup currently being operated on by a compute shader in uvec3 gl_WorkGroupID 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). gl_WorkGroupID gl_NumWorkGroups, gl_WorkGroupID, gl_LocalInvocationID Copyright 2011-2014 Khronos Group.
