3D模型变换的VC++源程序，用户可在此基础继续进行研究(3D model transformation of the VC++ source code, users can continue to study on this basis,)

立方体动态隐线算法，mfc实现立方体的动态消隐(Cube dynamic hidden line algorithm)

计算点云数据的法向量和局部特征,以备三维重建运用(The normals and features can be computed from a point cloud using the NormFet software)

点云数据转换文件。可以将PCL转换为PLY文件，反之亦然。其中用到了点云库PCL的代码。(Point cloud data file conversion. PCL can convert PLY files, and vice versa. Which uses a point cloud library PCL code.)

2D凸多边形的三角网格生成，可用gridgen。(2D triangular convex polygon mesh generation, available gridgen.)

说明：  四叉树（lod）实现地形三维可视化的程序，内有代码和数据(quadtree (incomplete) 3D terrain visualization procedures, which have code and data)

说明：  三维点云的伪彩色显示示例。自带5片点云用于测试。可平移、旋转、缩放视图；可单色、伪彩色显示点云。(An example of pseudo-color display of three-dimensional point clouds. It has five point clouds for testing. It can translate, rotate and zoom views; it can display point clouds in monochrome and pseudo-color.)
