Question:
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.
Replies:
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).
