本程序提供了三维坐标转换为二维坐标的算法，实现在屏幕上画三维图，并提供立方体绕任意轴旋转动画的算法。(procedures for the three-dimensional coordinates of the conversion of two-dimensional coordinates of the algorithm to achieve on the screen painting three-dimensional map, and provide cube rotating animation algorithms.)

matlab读入IGS文件，通过把IGS文件读入，实现三维数据点的显示，有利于matlab编辑(read into matlab IGS file read by IGS file to achieve a three-dimensional data points show favor matlab edit)

说明：  水平集（level set）中快进算法（fast marching）算法的matlab工具箱，内容很全面。(Level Set (level set), Fast Forward algorithm (fast marching) algorithm m atlab Toolbox, which is very comprehensive.)

斯坦福大学开发的一个三维点云重构生成网格，进一步生成NURBS曲面并加光照效果的系统。可以实现对生成的三维图形旋转，移动和多个角度图形的拼接(Stanford University in the development of a 3D point cloud generation reconfigurable mesh, NURBS surface generation further increases and the effect of illumination system. Generation can be achieved on the 3D graphics rotation, movement and different angles graphics Mosaic)

说明：  一个大规模地形现实和纹理映射的程序，从国外网站下载的，一般的机器根本跑不动，标准C编写，多平台可编译，供大家学习。(a large-scale topographic reality and texture mapping procedures from abroad website and general machinery simply could not, the standard C preparation, multi-platform can be compiled for the study.)

说明：  显示三维坐标系，及刻度，网格，并且可以随着自定义方位角和视角的变换而做出相应的改变。(According to 3 d coordinate system, and the scale, the grid, and it can with custom azimuth and perspective transformation and makes the corresponding change)

浙江大学的3D重建的论文，中文的，包括硕士论文和博士论文，对于研究3D重建的朋友或许有点帮助，谢谢(3D reconstruction of Zhejiang University)

说明：  本方法采用pca进行特征提取，knn分类器进行人脸识别。(The method of feature extraction using pca, knn classifier for face recognition.)

水波纹 3d 采用mesh方法，通过定点z值的不用来模拟水波纹的效果(wave ripper)

关于散乱点三角网格化的论文，非常有参考价值。(On the triangular grid paper, is a valuable reference.)
