Abstract: There are well known shading algorithms (Gouraud, Phong) for the surfaces shading. The problem is that such algorithms just approximate the real shading. Precise shading algorithms require the values of normal vectors at all points of rendered surface. Computation of normal vector for Cartesian and triangular parametric surfaces is presented in the paper.
Keywords: Beziér patch; normal vector surface; shading
