Description
TessLevelOuter
-
Decorating a variable with the
TessLevelOuter
built-in decoration will make that variable contain the outer tessellation levels for the current patch.In tessellation control shaders, the variable decorated with
TessLevelOuter
can be written to, controlling the tessellation factors for the resulting patch. These values are used by the tessellator to control primitive tessellation and can be read by tessellation evaluation shaders.In tessellation evaluation shaders, the variable decorated with
TessLevelOuter
can read the values written by the tessellation control shader.
