| 中文摘要: |
| 在CAD软件的实际运用中，曲线主要采用B样条曲线，曲面主要采用B样条曲面。如果对B样条曲线和曲面的数学理论有一些基本理解，则对曲线和曲面的创建与控制就会有较大的帮助。不同的CAD软件会采用不同的B样条算法。讨论了Auto—CAD、CATIA和Rhino三种类型的CAD软件中的B样条曲线。并结合CATIA中自由曲面模块中的相关操作，进一步说明非均匀有理多项式B样条曲线在CATIA中是如何运用的。为CATIA曲线及曲面的相：关学习提供一点参考。 |
| 英文摘要: |
| In the practical application of CAD software, B-spline curve is the mainly curve which is being used. And B-spline surface also plays a important role is the curved surface. Have some basic understanding of the B-spline curves＇ mathematical theory will make a great contribution to the creation and control of curves or surfaces. Make discussing about B-splines curve in three types of CAD software： Auto- CAD, CATIA and Rhino. And then give a further explanation of the roles that Non Uniform Polynomial B-Spline Curve plays in the freedom surface module. Want to provide a little information in the learning of curves and surfaces. |
