problem set: assignment 4
--------------------------------------------
Requirements:
  transform normals: yes
  backface culling: yes
  directional light: yes
  ambient light: yes
  per triangle shading: yes
    ambient reflection: yes
    diffuse reflection: yes
  clipping in z: yes
  z-buffering: yes

Optional:
  point light: 
  multiple lights: yes
  specular reflection: yes
  Gouraud shading: yes
  Phong shading: yes (two kinds!)
  scene: 
  interface: switch between shadings and change specularity constant

functionality (0-90): 90
extra credit (0-10): 10
total (0-100): 100
--------------------------------------------
notes: You easily earned full extra credit for implementing both Gouraud
and Phong shading (while experimenting with negative specularity).
Excellent job.
