gl_TessLevelInner — contains the inner tessellation levels for the current patch
// In tessellation control shaders
patch out highp float gl_TessLevelInner[2] ;
// In tessellation evaluation shaders
patch in highp float gl_TessLevelInner[2] ;
Available only in the tessellation control and evaluation languages, gl_TessLevelInner
is used to assign values to the corresponding inner tesellation levels of the current patch. The values written
into gl_TessLevelInner by the tessellation control shader are used by the tessellation
primitive generator to control primitive tessellation and may be read by the subsequent tessellation evaluation shader.
As inputs to the tessellation evaluation shader, gl_TessLevelInner contains the values
written by the tessellation control shader.
