DownsamplePointCloud

做课程设计的一个代码，是opengl工程，立方体旋转，每个立方体的面帖有不同的图。(The code to do the course design is a opengl project, cube rotation, the face of each cube posts have different plans.)

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：  这时一个delaunay三角网的程序，功能强大，并里面有详细说明和程序及原代码。能创建二维和三维的，且能生成模拟的3D图。(then a triangular network nodes procedures, powerful, and there are detailed procedures and the original code. To be able to create two-dimensional and three-dimensional and can generate simulated 3D map.)

开源的3D引擎。简单实用。 带有示例代码，和引擎代码(Open-source 3D engine. Simple and practical. With the sample code, and the engine code)

基于VTk的点云显示，构网（Delaunay Tin，包含二维，三维，及TEN）。附有详细的代码注释，也有实例数据。(The point cloud based VTk display, configuration network (Delaunay Tin, including 2D, 3D, and TEN). With detailed code comments, but also instance data.)

光照模型的完整源码，内含Gouraud和phong两种明暗处理。(Complete source of illumination model, to containing Gouraud and phong two-shading.)

一个演示3D波浪的图形类(A demonstration of 3D graphics-type wave)

说明：  三维地形实时动态显示的核心代码---来自<<Visual C++ 编程技巧典型案例解析>>(Real-time dynamic display of three-dimensional topography of the core code--- from <<Visual C++编程技巧典型案例解析>>)

二维图形的变换，平移，翻转，尺度变换，反射对称，用MFC实现，这是别人的实现，我又给添加了既平移又反转的情况演示(two dimension graphic convert, translate ,rotation,scaling ,reflection symmetric, used by MFC implemented ,though other implement ,but i add the translate and rotation )

模拟偏振光在散射介质中的传播，利用3D给出很好的视觉效果(Simulation of polarized light propagation in scattering medium)
