| 摘 要： | 在曲线曲面的设计中,经常遇到特殊形状的设计,如直线中插入尖点和直线段,曲面中插入棱线和直纹面,这些简单重型值点方法来实现,但若在曲面中夹尖点,平面片和棱角仍存在较大困难,而这些特殊形状在曲面设计中又经常用到,本文通过巧妙地构造型值点阵,得到了夹平面片,尖点和棱角的3次B样条曲面的构造原理与方法.图8,参6.

| Abstract: | When designing curves and surfaces,we often need insert some special shapes.For example,inserting cusps and lines in a curve and crease and ruled surfaces in a surface.This can be obtained by multipoint-method.But it's still difficult to insert cusps,plain patches or arrises into a surface.While these special shapes are common in geometry designs.In this paper,principles and methods on constructing plain patches,cusps and arrises in a surface were put forward through founding some point-matrixes.8figs.,6refs. |
