WebThe Tessellation Evaluation Shader (TES) stage comes last, and it applies the interpolation or other operations used to compute user-defined data values for primitives generated by the fixed-function tessellation … WebThe tessellation shaders receive the array of transformed vertices, i.e. the patch, and commonly subdivides it in smaller primitives. As 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: ? 1
