gl_LocalInvocationIndex — contains the local linear index of work item currently being operated on by a compute shader
in uint gl_LocalInvocationIndex ; 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.
