OpenGL ES does not have tessellation shaders yet, but Intel’s Bay Trail platform now has an extension that … WebFor quads we have 4 outer tessellation levels and 2 inner. Because, surprisingly :-), we have 4 edges and 2 dimensions to subdivide inside quad. If you calculate tessellation levels dynamically (e.g. based on distance from camera) care should be taken to set correct index in gl_TessLevelOuter/Inner.
