A reminder: you are free to collaborate, but you must understand and write up the final answers by yourself!

Consider the 16 combinations of: near or far viewer; near or far light source; planar or curved surfaces; and, diffuse or specular material. Label each combination with the lowest cost shading model which will produce correct results. The choices for shading models are 'Flat', 'Gouraud', 'Phong', and 'Other'. Other is a shading model better than Phong.
You should definitely consider the derivative of the reflectance vectors when doing this problem!
Near light Far light Near view Far view Near view Far view Diffuse surface Curved Planar Specular surface Curved Planar
Correct model used 0: Incorrect models 16: Model selected based on vector derivatives -
Explain why the incremental effort to go from flat shading to Gouraud shading is small, but the incremental effort to go from Gouraud shading to Phong shading is large.
