I need to know how to make equations that represent 3-dimensional shapes in the coordinate plane so that I can enter these equations in a computer program I am working on.

The most common technique for doing this is to use polygonal surfaces and polyhedra, so that the shapes consist of lots of flat faces. You specify the polyhedra either by specifying all the vertices, or by specifying the normals to faces and one point in the face. Actually, they could use other techniques too - you might check into some books on 3-D graphics techniques or on finite-element approaches (or whatever they call the stuff used in CAD/CAM work).
