We built a set of objects to encapsulate the 3d OpenGL data and then we
wrote methods to load the data from a file. We can add new formats so our
code can read VRML, 3DMF, or whatever other format we choose to create.

You should build an internal format that is optimal for OpenGL and import
your data from the file format you use into this format.

Once we had our system working we added new file types which allow use to
specify parameters for program created shapes (spheres, boxes, etc.). This
allows quick creation of simple models.
