非均匀有理B样条理论在自由曲面造型中的应用

Theory of NURBS and Its Application in Free-form Surface Design

探讨了应用非均匀有理B样条(NURBS)的曲线曲面理论理论进行复杂曲线曲面造型的基本方法,给出一个在UG软件中运用该理论进行复杂曲面建模的实例.实践结果表明:应用NURBS技术将大大提高利用计算机设计复杂曲线曲面模型的精度和效率.

Studies the principles and method of NURBS (Non-Uniform Rational B-Spline), and the processes of its application in free-form curve and surface modeling are introduced with examples. The result show that the application of NURBS technology can improve the efficiency and accuracy of computer design for complicate curve and surface model.
