摘要/Abstract

摘要： 非均质NURBS体参数化模型能连续表达整个实体内部的材料信息而受到重视,但直接对该模型进行切片用于快速成型目前并没有相关研究。提出一种非均质NURBS体参数化模型切片算法。通过在控制点上附加材料组分信息且通过不同基色表示不同的材料成分。通过等参数线划分网格,并找出与切片平面相交的网格单元,然后求出切片平面对各网格单元的截面,得到带有材料分布信息的切片截面。切片结果表明,非均质NURBS体参数化模型切片算法能有效的获得非均质实体模型的包含材料组分信息的截面信息,为基于NURBS体模型的非均质产品的快速成型提供技术支撑。

Abstract: Heterogeneous NURBS Volume Parametric Model is attached importance for its ability to express the Information of materials continuously. But there is scarce study on the slicing algorithm of heterogeneous NURBS volume parametric model for rapid prototyping yet. A slicing algorithm for heterogeneous NURBS volume parametric model was proposed. The materials were expressed by putting the material information on control points and display different color to represent different materials. The model was divided into patches by iso-line. Find out the patches which intersect with the given cutting plane, then get the sections of the meshes containing material information. The results show that slicing algorithm for heterogeneous NURBS volume parametric model can get the section with material information effectively, and provide technical support for rapid prototyping of parametric products.

Key words: heterogeneous products, rapid prototyping, NURBS volume, slicing algorithm
