NAME

       gl_TessLevelInner - contains the inner tessellation levels for the current patch

DECLARATION

       // In tessellation control shaders

       out float gl_TessLevelInner[2] ;

       // In tessellation evaluation shaders

       in float gl_TessLevelInner[2] ;

DESCRIPTION

       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, if present. If no tessellation control shader
       is present, it contains the default tessellation level.
