What kind of surface plot? Wire frame? Wire frame with hidden line removal?
Flat shaded polygons? Smoothed polygons?
Unless your requirements are extremely modest, you probably want to use
a 3D API such as Mesa or OpenGL rather than roll your own.

Foley, van Dam, Feiner, and Hughes is the standard graphics reference
(I forget the exact title -- something like _Computer Graphics, Principles
and Practice_, I think). It should have what you want for simple surfaces
and hidden line removal. Just about any basic text on CG should give you
a start if you're looking at writing something of your own.
