I need to describe 2D objects using what Samet calls the boundary
model (He describes this for modeling 3D solids). It seems to me that I can
use analagous model for 2D using edges, vertices, polygons and no faces. I am
starting to work on this subject and I would appreciate if some one can give
some pointers to algorithms/code/references/data-structures that I could use
to understand how it works.
Thanks in advance.
