NAME¶
gl_LocalInvocationIndex - contains the local linear index of work item currently
being operated on by a compute shader
DECLARATION¶
in uint gl_LocalInvocationIndex ;.SH
"DESCRIPTION"
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.
