摘要
在计算机辅助设计领域内Bezier曲线及曲面已广泛地应用于自由曲线和自由曲面的构成,为各种工程设计提供了一种方便易行的工具。在实际应用中常把一段自由曲线分为为若干段三次Bezier曲线,使整个自由曲线的形状便于构造与控制。本文着重讨论三次Bezier曲线及曲面在连接时如何保证它们的连续性,以及算法如何实现。
The Bezier curves & surfaces have been widely used in CAD fields for constructing free curves and free surfaces. A convenient tool is provided in engineering design by using Bezier curves and surfaces. In practice, free curve is usually divided into some pieces of cubic Bezier curves, so that its shape is easy to constract and control. In the paper we discussed that the continuities of two cubic Bezier curves and surfaces in connection, and the algorithm about this.
