I'm looking for a book/notes/post that gives a generalized algorithm or code
for rendering 3D mathematical functions.  (i.e. surfaces of revolution)  

ideally, it would allow a place for whatever formula is being used to be 
"plugged in" but that isn't strictly necessary.



Specifically, I'm working on a an SGI Presonal Iris.  My current (and
admittedly naive) strategy is to simply calculate the z values over some 
patch of the surface, transform these vertices into polygons, store the poly-
gons (with vertex normals) in a list, and just run through the list, letting
the hardware lighting functions etc. take care of the rest.  


any help is appreciated.
