摘要
曲线不同表示形式间的相互转换是 CAD/CAM领域中的重要研究课题之一。基于 B样条曲线的节点插入技术 ,就 CAD/CAM中广泛采用的曲线的 NURBS表示和 Bézier表示之间的快速转换问题进行了讨论 ,给出了 NURBS曲线转换为 Bézier表示的优化算法。结果表明所给算法计算量最小、通用性强、稳定、可靠。
Conversion between different representation schemes of curve is an important topic in CAD/CAM. The conversion of NURBS curve to piecewise Bézier representation is discussed. Based on inserting knot technique, an efficient algorithm for the conversion of NURBS to piecewise Bézier representation is presented. Compared to other conversion algorithm, this algorithm has those advantage, such as reduction in computation, stable and robust.
