The are some selected projects that I did for the interactive graphics class I took Spring 2004 for my master's in computer science through the University of Southern Mississippi. All of this was done with OpenGL.

Earth and Moon
Attempts to mimic the Earth/Moon system with the proper ratios of rotation and revolution. Does not mimic gravitational pull or axis tilts.
Height Fields
Creates a 3d representation of an 8 bit bmp that is used to simulate some terrain. An image is then over-laid the resulting surface to simulate a vegetation covered surface.
This was done within VRCO's CAVELibs for OpenGL; the red thing in the 2nd image is the wand in the cave simulator, but textures and height fields are implemented using the OpenGL libs. The lines are the simulated walls. Check out VRCO's site. They are good about giving temporary licenses for educational users.

Mesh Viewer Reads in a 2d finite element mesh using the ADCIRC fort.14 format, and generates a 3d representation using the bathymetry (depth) to describe the heights.
