WebAs opposed to other OpenGL primitive types, patches have a user-defined number of vertices. Function glPatchParameteri is used to set this value, which remains constant in draw calls, as follows: glPatchParameteri( GL_PATCH_VERTICES, verticesPerPatch ); where verticesPerPatch must be an integer in [1, GL_MAX_PATCH_VERTICES].
