Summary
A diagram showing the vectors used in calculating Blinn-Phong lighting, relative to a surface point:
- N, the surface normal
- L, normalized vector in direction of light source
- R, normalized vector in direction of specular light reflection
- V, normalized vector in direction of viewer
- H, the "halfway" vector, a normalized vector in direction of (V+L)/2
