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
.
