.SH "DESCRIPTION"
.PP
Available only in the tessellation control and evaluation languages,
\fIgl_TessLevelInner\fR
is used to assign values to the corresponding inner tesellation levels of the current patch\&. The values written into
\fIgl_TessLevelInner\fR
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\&.
.PP
As inputs to the tessellation evaluation shader,
\fIgl_TessLevelInner\fR
contains the values written by the tessellation control shader, if present\&. If no tessellation control shader is present, it contains the default tessellation level\&.
