查询词典 polygon

Firstly,3D point clouds produced by 3D laser scanner are converted into polygon mesh.Then,normal vectors and areas of every polygon mesh are computed and some candidate regions are obtained using region dilation strategy.Finally,the 3D laser scanning data is segmented into regions of similar orientation after the elimination of the insignificant regions.

首先将三维扫描表面数据转化为三维网格模型；然后利用同一区域中相邻网格具有相似法线方向这一性质，使用区域膨胀策略生成若干获选表面区域；最后通过去除候选区域中的噪声区域得到最终表面区域分割结果。

The corners of each new polygon are at the intersections of the borders of the original polygons; hence computing the coordinates of border intersections is a vital function in polygon overlay.

每个新的多边形的角隅都位在原始的多边形的边之交叉点上；因此，计算这些交叉点的座标在多边形的叠合中是绝对必要的。

The results are much better than the other approaches'. Then we give another method for approximating offset curves. The circle is first approximated by regular polygon within some tolerance. The exact offset curve is then approximated by the convolution of the regular polygon with a B-spline curve or a NURBS curve having the same degree.

与此同时作者从基圆的正多边形逼近出发，通过求解包络的技巧给出了等距曲线逼近的另一个算法，可整体估计误差，所得的等距逼近曲线为与基曲线同次数的B样条或NURBS曲线，克服了国际上现有同类算法中逼近曲线次数几倍于基曲线次数的缺陷。

Local topological information is imported to the altered polygon in this new algorithm.The arcs which are joined in the same node are ordered by means of bina sorting tree,and the minimal polygons are built by the right sequence of arcs,then polygon overlaying is finished.

通过在无拓扑矢量数据中局部引入拓扑关系，对同一结点连接的弧段，采用二叉树方法进行排序，构建最小多边形，完成无拓扑信息的矢量图形的重组，并对新算法与已有算法的结构进行了对比。

A simple polygon is a polygon with no two non-consecutive edges intersecting.

一个简单的多边形是一个没有两个非连续边缘交叉多边形。
