 Amazon.com: Books: Geometric Modeling (Site not responding. Last check: 20071021) 
  It integrates the three important functions of geometric modeling: to represent elementary forms (i.e., curves, surfaces, and solids), to shape and assemble these into more complex forms, and to determine concomitant derivative geometric elements (i.e., intersections, offsets, and fillets). 
  Geometric Modeling, Second Edition serves as an invaluable guide to computer graphics and CAD/CAM specialists, applications designers, scientific programmers, teachers, and students. 
  I think everyone who is interested in geometric modeling will find it's beneficial for research as well as for applications.
