| 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. | |
| 10 | </p><p> | |
| 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. | |
