说明：  一个关于地形LOD渲染得例子，给出了渲染得全部代码(a rendering of the terrain in LOD examples given in all rendering code)

去年情人节写的一个程序。设计场景：在漫天玫瑰飘洒之下，对尔之祝福姗姗而来。(a program to make your girl happy!I hope this is useful to you.)

这个程序是用来将三维坐标投影成二维的c++程序。(This program is a three-dimensional coordinate projection into two-dimensional C++ program. . .)

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.)

Prewitte边缘算子法(Prewitte Edge Operators)

用MFC实现的3D图形学中的立方体，可旋转，有三种投影方式，正交，透视，斜投影三种(MFC achieved with 3D graphics in the cube can be rotated in three projection mode, orthogonal, perspective, oblique projection of three)

说明：  利用实时最优化自适应网格算法绘制大规模地形，算法经典，绝对可用，注释清楚。(optimize the use of real-time adaptive grid massive terrain mapping algorithm, the algorithm classics, and absolutely available Notes clear.)

3维圆柱面，可以上下左右不同视角观看，使用上下左右方向键操作(3D Cylinder)

Voronoi图是以两点间线段的长度作为距离 ,对平面的一种分割。然而 ,在地理环境中 ,存在着许多自然的或人为的障碍 ,使得从一点到另一点不能直线到达。为了扩大Voronoi图的应用领域 ,本文对传统的Voronoi图进行扩充 ,给出了障碍Voronoi图的定义、性质 ,以及离散生成线段障碍Voronoi图的方法(Voronoi diagram based on the length of line between two points as the distance from a partition of the plane. However, in the geographical environment, there are many natural or man-made obstacles, making from one point to another point of arrival can not be a straight line. In order to expand the area of Voronoi diagram, Voronoi In this paper, the traditional expansion plans, given the obstacles to the definition of Voronoi diagram, the nature of the discrete Voronoi diagram generation segment of the barrier method)

说明：  实时图形设计 3d场景漫游 3dmax模型 场景中包括树木 房屋 道路 移动小车 以及 billboard 绘制的树木 支持人机互动 场景漫游(This code is the assignment for our real-time graphic designing. It includes many scenes like houses,trees using the billboard skill, roads and the cars.)
