Animation: Assigning Materials Shading Models
- There are nine shading models plus ray tracing:
- Oren-Nayer Blinn - Similar to Blinn but with more subtle highlights making it more suited for fabrics and other non-reflective surfaces
- Anistropic - This produces a bright highlight on a curved surface stretched in one direction
- Strauss - This produces an enhanced metal effect
- Miltilayer - This enables you to layer specular highlights on top of each other
- Raytracing - The colour and value of each pixel on the screen is calculated by casting an imaginary ray back from the viewer’s perspective into the model to determine what light and surface factors are influencing it. The ray can be bounced off surfaces and bent - just like real light - producing excellent shadows,reflections and refractive effects.
