3D Grid: Fix grid passing through objects too much
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.
