Preface to the
English Edition
CAD/CAM (Computer Aided Design and Manufacture) puter
graphics have undergone rapid and striking development in the last 20
years. Geometric modeling is one of the most important basic tools in these
fields.
According to the definition given by Forrest, computational geometry
is concerned puter-based representation, analysis and synthesis of
shape information. This subject is also puter Aided Geometric
Design (CAGD) by many other authors. The study of free-form curve and
surface modeling is the main aspect in geometric modeling.
Basic theories, geometric properties, and numerical algorithm
