WebQuad tessellation is similar to trianlges. The difference is that instead of barycentric coordinates gl_TessCoord.xyz which define point on a triangle (tcPosition) you have 2-component coordinate gl_TessCoord.xy (they also span in [0-1] range).. Hull shader (or Tessellation Control Shader in OpenGL terminology) looks pretty straightforward: 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
