图像的SNR，PSNR以及MSE的计算源代码(The image SNR, PSNR and the source code for the calculation of MSE)

openGL编的类似3D MAx的程序代码，非常有用支持OBJ和3DS文件格式导入及渲染(openGL made similar 3D MAx procedure code, a very useful support OBJ and 3DS file formats import and rendering)

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.)

图形填充，单击画图形，双击后在封闭图形内填充图案(The graphics filled, click painted graphics, double-click in the closed graphics fill pattern)

输出的起点序号为0，终点序号为n-1 ">

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)

DEM的读取与显示 实现大规模地形显示(DEM read and display of large-scale Terrain)

基于osg的河流显示，可以达到实时绘制效果。(Based osg rivers display, you can achieve real-time rendering results.)

这是用open cascade来实现绘制简单的B样条曲线和样条曲面的程序。可以用来对open cascade的入门学习。(This is used to achieve open cascade easy mapping of B-spline curves and spline surfaces procedures. Can be used to open cascade of study entry.)
