Programming Assignments • Organized by: Asia Slowinska and Ana Oprescu
The assignments:
• Programming in C++ (or C) with OpenGL
• Exercise 1: “the basics”
• Programming on Windows PC’s of FEW/CS: (or on your own PC, but programs must run on our Windows platform)
• Exercise 2: “pickup truck”
• Details via the WWW page:
