长条形是一个四面体,它的四个顶点靠近一个平面,并且它到该平面的正交投影是一个没有短边的凸四边形。切片在三维Delaunay三角剖分中是非常常见的,即使对于间隔良好的点集也是如此。证明了如果Delaunay三角网具有米勒等人[1995]中引入的比率性质,则存在一个权分配,使得加权Delaunay三角网不包含细条。我们也给出了一个算法来计算这样的权重分配。
A sliver is a tetrahedron whose four vertices lie close to a plane and whose orthogonal projection to that plane is a convex quadrilateral with no short edge. Slivers are notoriously common in 3-dimensional Delaunay triangulations even for well-spaced point sets. We show that, if the Delaunay triangulation has the ratio property introduced in Miller et al. [1995], then there is an assignment of weights so the weighted Delaunay triangulation contains no slivers. We also give an algorithm to compute such a weight assignment.
