OpenGL ES does not have tessellation shaders yet, but Intel’s Bay Trail platform now has an extension that … Web29 de ago. de 2014 · The tessellation shader is for variable subdivision. An important part is adjacency information so you can do smoothing correctly and not wind up with gaps. You could do some limited subdivision with a geometry shader, but that's not really what its for. Geometry shaders operate per-primitive.
