Virtual Trackball Jumpstart
Here's some help getting started with the virtual trackball part of Assignment 3: grab trackball.c. Initially the sphere doesn't move. Fill in the parts labeled "TODO" with the equations discussed in class, and you should end up with a running program similar to trackball.exe.
Quotes from Dijkstra and Knuth

And Donald Knuth, from an interview in Dr. Dobb's Journal
DDJ: You've mentioned Edsger Dijkstra. What do you think of his work?
DK: His great strength is that he is uncompromising. It would make him physically ill to think of programming in C++.
