For this we need to add a bias depending on the viewing angle. But increasing the hardness of the test make float precision issues in the mesh transformation more prominent (actual geometry is far below the surface). So to solve this issue we use a more subdivided grid mesh 8x8 quads instead of 1 triangle.
