Introduction to part III
The two chapters in part III leave behind basic principles and introduce some
specific and more sophisticated, yet still practically useful, topics.
The modeling algorithms described in chapter 10 were chosen because they
constitute some of the most essential tools for constructing polygonal models
algorithmically (as opposed to a simple tool that allows a program’s user to
draw a curve in 3D); for example, triangulating an arbitrary polygon (that might
contain holes) is a very tedious job when ...
