CS 445: Topics for Sept 9/11, 2014

• Labs:

  • Complete: Lab 1: Building a Ray Tracer, Part 1
  • Begin: Lab 1: Building a Ray Tracer, Part 2

• 3D Rendering Methods:

  • Scanline
  • Ray Tracing, also see Povray
  • Global Illumination

• Continue discussion of Ray Tracing Notes (pdf)

• Equations for Objects:

  • Sphere
  • Plane
  • Also see Ray Tracing Notes for Spheres and Planes.
  • Cones
  • Cylinder
  • Algebraic Surfaces
  • Steiner Surfaces

• Lighting and Shading

  • Phong Lighting
  • Note, we will need normals for all of the above shapes. Given an equation of a surface f(x,y,z), the normal is the gradient of f: normal to f = ∇ f = ( ∂ f/ ∂x, ∂ f/ ∂y, ∂ f/ ∂z)
  • For an entertaining lecture on lighting, see Knoll's Computer Class, episode 1
