| 26 | In the compute language, <function>gl_LocalInvocationIndex</function>\r | |
| 27 | is a derived input variable containing the 1-dimensional linearized index of the\r | |
| 28 | work invocation within the work group that the current shader is\r | |
| 29 | executing on. The value of <function>gl_LocalInvocationIndex</function> is equal to\r | |
