gl_PatchVerticesIn — contains the number of vertices in the current patch
in highp int gl_PatchVerticesIn ;
Available only in the tessellation control and evaluation languages, gl_PatchVerticesIn
contains the number of vertices in the input being processed by the shader. A single tessellation control or
evaluation shader can read patches of differing sizes, and so the value of gl_PatchVerticesIn
may differ between patches.
