Today we’ll be working with creating a trackball, and going over Assignment 3. To start off with, you will need these files, as per usual: Makefile, Point.cpp, Point.h, Vector3.h, Vector3.cpp. Also, you will need TrackBall.cpp. One issue with the Makefile is that this is one used for a previous lecture, so make changes so that it compiles TrackBall.cpp.
We will be going over what to do in class to make the TrackBall, but it will be up to you to write the code. If you miss the lecture, a discussion of both of these concepts are on Steve’s site. Assignment3, and TrackBall.
