This is a project I started in 1998 to implement a general 3D sim in C++ using MFC and OpenGL. I never completed it, but as much as I did is available for anyone to look at and play with.
This is an MFC application that uses OpenGL to render 3D objects. The shapes and quaternion classes show that I have a good understanding of inheritance and object oriented design. The code was written by me as a hobby in a couple months of spare time. The comments are not as complete as I would put into production code.
