摘要
曲面造型(Surface Mode ling)是计算机图形学和计算机辅助几何设计(Com pute r Aide d Ge om e tric De s ign)的一项重要内容,主要研究在计算机图像系统的环境下对曲面的表示、设计、显示和分析。它起源于飞机、船舶的外形放样工艺,由Coons、Be zie r等大师于1960年代奠定其理论基础。而在此技术上发展的自由曲面造型将造型的自由发展提升了一个新台阶,文中阐述了曲线造型的数学理论,并以一个汽车外形设计和分析的例子说明其重要性。
Surface modeling is an important content of computer graphics and computer aided geometric design,it mainly researchs in computer image system under the environment of the surface the representation,design,display and analysis.It originated in the plane,shipping appearance by lofting craft.Masters of the 1960s such as Bezier Coons,lay its theoretical basis.And on this base the freedom of free surface modeling ascends to a new stage,this paper explains the mathematical theory of curve modelling,followed by designing example of a car shape to indicate its importance.
