复杂非限定约束曲面造型

Complex non-limited constraint surface modeling

文章介绍了两种曲面建构方法,并阐述了使用ISDX构造自由曲面模型的特点、方法和注意事项,指出了构造自由曲面模型和参数化曲面模型的最大区别是对曲率表的使用方式。

This paper briefly introduces two kinds of surface construction methods,explains the features,methods and points for attention for constructing free-form surface model with ISDX,and points out that the biggest difference between constructing free-form surface model and parametric surface model is the using ways of curvature table.
