Abstract

One important area of Computer-Aided Geometric Design (CAGD) is concerned with the approximation and representation of the surfaces of solid objects. Accurately describing the shape of an object so that the description is useful to designers who must decide how to manipulate it is an important problem. B-spline techniques promise greater versatility in describing complex surfaces than other techniques, thus the B-spline surface is highlighted in the field of constructive solid geometric modeling. A method for drawing complex surfaces by using B-spline techniques is presented. The tensor product surface scheme is developed for constructing sculptured surfaces. Also, the basic principle of multivariate B-splines, i.e., nontensor product surfaces, the light of tomorrow in CAGD, is introduced.
