摘要：
In this paper we study in depth a new modeling method for parameter curves and surface-hyperbolic polynomial uniform B-spline surfaces with shape parameter Based on this model we give an example of free-form curve modeling and analyze the effect that different shape parameters have on the curve shape In light of computer graphics theories we develop a space free-form surface modeling system on the Microsoft Windows operating system By means of the prototype system we perform free-form surface modeling give examples for its application and discuss how the adjustment of the shape parameter affects the shape of free-form surfaces (C) 2009 Elsevier Inc All rights reserved
