查询词典 triangular number

This paper studied deeply on 3D reconstruction and visualization. Based on the detailed analysis of the MC algorithm, which is used for extracting Iso-surface from volume data field, this paper presented a new method of directional smoothing and triangular curved surface reconstruction.

为了在微机上实现较好的三维重建效果与理想的交互显示速度，本文主要研究内容和结论如下：首先，对三维重建与可视化技术进行了深入研究，在对用于从体数据场提取等值面的经典MC算法深入分析的基础上，提出了等值面方向平滑处理与三角B－B曲面重构方法。

Due to the irregular distribution of space mesh data, the contour of surface cannot be gained from coordinate of points directly. So a method to detect edges of triangular mesh surface is brought out in this passage.

由于空间网格数据分布不规则，不能从点的坐标直接得到曲面的边界，因此提出了一种空间三角网格曲面的边界提取方法，通过判断一个点的邻接点是否都能通过三角网格的边组成闭合曲线来获取边界点。
