localValue
-
The requested type.
Return value
The specified local value. If the source lane is inactive, the results are undefined.
Remarks
For more information on quads, refer to Overview of Shader Model 6.
This function is supported in pixel and compute shaders starting with shader model 6.0. In compute shaders targeting shader model 6.0 through 6.5, the mapping of threads to quads is implementation-dependent. Shader model 6.6 defines the quad layout for compute shaders and adds support for this function in amplification and mesh shaders.
