That is certainly the canon book for understanding the mathematical
underpinnings of what NURBS are, effective and descriptive mathematical proofs
for how they describe geometry, what they describe, their fundamental
limitations, some information on how to go about implementing or evaluating
them, and much more. It's a dense book.
However, I think it's about as useful an introduction to implementing NURBS
support for a solid modeling CAD system as reading The Joy of Cooking is for
running a restaurant. Sure, keep it handy and reference it often, but how you
use that information is the real problem. ;)
Cheers!
