Write a routine to implement Eq. 10-17 for diffuse and specular reflections using a single point light source and Gouraud surface rendering for the polygon facets of a tessellated spherical surface. The object description is to be given in polygon tables, including surface normal vectors for each of the polygon faces. Additional input includes values for the ambient intensity, light-source intensity, surface reflection coefficients, and specular-reflection parameter. All coordinate information can be specified directly in the viewing reference frame.
