This was the first 3-d project I did in for my Computer Graphics class. It was written in Visual C++. It uses fltk for the user interface, and OpenGL for 3-d rendering.
The program allows the user to create a spline track for a one car roller coaster. Scenery objects can be placed in the window, the camera can be moved, and a light source can be positioned.
