</h2><p>
6 Available only in the tessellation control and evaluation languages,
<code class=
"function">gl_TessLevelInner
</code>
7 is used to assign values to the corresponding inner tesellation levels of the current patch. The values written
8 into
<code class=
"function">gl_TessLevelInner
</code> by the tessellation control shader are used by the tessellation
9 primitive generator to control primitive tessellation and may be read by the subsequent tessellation evaluation shader.
11 As inputs to the tessellation evaluation shader,
<code class=
"function">gl_TessLevelInner
</code> contains the values
12 written by the tessellation control shader, if present. If no tessellation control shader is present, it
13 contains the default tessellation level.
