Intermediate Topic 22 of 49 Graphics, Vision & Media
Shading Models
Phong and Lambert lighting calculations.
How it works
Lambert diffuse intensity ∝ N·L; Phong adds specular (R·V)^shininess; Blinn-Phong uses a half vector; physically based rendering (PBR) uses roughness and metalness with energy conservation.
Where it is used
Lighting surfaces.
Common pitfall
Normals must be normalized after interpolation.
Where it fits in the course
