[csu540-f05-rpf] Programming Assignment 2

[Philip Lee]

I've started the programming assignment 2 and I have some problems trying
to figure it out how to implement the Ray-Sphere intersection foumula in
the book. What are d and e? And how do we draw the sphere when the ray has
intersected a point in the sphere? Does this Ray-sphere intersection work
like the Ray-Triangle Intersection where the ray intersects all the points
inside the triangle?
