Ray Tracing Notes 2

• Finding surface normals – use the gradient
• Ray traced shadows (see notes)
• Using recursion to implement reflections (see notes)
• Anti-aliasing:
  • In Hypergraph
  • In Povray (may be out of date)
  • Also see Povray’s docs
• Textures
  • Look at code and at updated Ray Tracing Notes
  • 2D Procedural Textures
  • Mapping and UV Coordinates
• Other misc texture topics:
  • Bump Mapping
  • Setting up UV Coordinates for odd ball shapes
  • 3D Textures
  • Perlin Noise, code
