| 摘 要： | 针对从散乱点云重建三角网格曲面的问题,提出了一个插值数据点的简单且鲁棒的曲面重建算法,其中点云是从任意拓扑的模型表面上采样得到的。利用最小二乘平面拟合方法计算每个点处的曲面法向,并计算两个等距面上相应的采样点,在构造好所有等距点的Delaunay三角剖分后,利用marching tetrahedra方法即可得到一个插值...

| Abstract: | A simple and robust algorithm which constructs an interpolating triangular mesh from a close point cloud sampled from arbitrary genus model is introduced.At first,surface normal on every point is estimated by the least squares best fitting plane method and offset points are computed.After the Delaunay triangulation of the points from two offset surfaces has been constructed,a triangular mesh is got using simple marching tetrahedra.The experimental results show that the method is efficient. |
