It is available for general planar polygons (manifold or non-manifold, with or without holes). Edges of the two general polygons are subdivided at the intersection points and touching points. Thus, the boundaryof the Boolean operation resultant polygon is made of some whole edges of the polygons after the subdivision process. We use the simplex theory to build the basic mathematical model of the new algorithm. The subordination problem between an edge and a polygon is reduced to a problem of determining whether a point is on some edges of some simplices or inside the simplices, and the associated simplicial chain of the resultant polygon is just an assembly of some simplices and their coefficients of the two polygons after the subdivision process. Examples show that the running time required bythe new algorithm is less than one-third of that bythe Rivero and Feito algorithm. 关键词 Curve Modeling Packages Surface Geometric Algorithms Computational Geometry Solid Languages Geometric Modeling And Object Representations And Systems Boolean Operation Polygon Intersection 收录类别 SCI 文献类型 期刊论文 条目标识符 http://ir.ia.ac.cn/handle/173211/13119 专题 09年以前成果 通讯作者 Peng, Yu 作者单位 1.Department of Computer Science and Technology, Tsinghua University2.School of Software, Tsinghua University 推荐引用方式GB/T 7714 Peng, Yu,Yong, Jun-Hai,Dong, Weiming,et al.
