Shading Model:
- Also call "Light Transport Theory: Pointwise Radiance Evaluator "
A Shading Model is a procedure which takes a projection point, a view direction and a 3D scene description to compute the color (or radiance) going to that point along that direction.
至於 surface characteristic .......
- object surface characteristic = wire frame, solid
- object shape characteristic = cube, sphere
engineering 裡面好似都有類似既 terms, 不過我就唔識喇
