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)

转动的彩色立方体（1~2人）谭飞、吴颖颖 1) 绘制一个不停转动的彩色立体球，可以绕着任意方向旋转； 2) 采用一定的光照明技术，考虑环境光、反射光以及镜面光的作用； 3) 采用消隐算法，体现立方体表面的遮挡关系； 4) 具有较好的动画效果，消除闪烁现象； 5) 不可以采用OpenGL中的函数。 (Rotating color cube (1 ~ 2)谭飞,吴颖颖1) draw a non-stop rotation of the color three-dimensional ball, you can spin around in any direction 2) the use of certain lighting technology, consider the ambient light, reflected light and the mirror The role of surface light 3) the use of blanking algorithm, reflecting the relationship between cube block surface 4) has good animation effects, to eliminate flicker phenomenon 5) can not be used in a function of OpenGL.)

LOD地形小演示 内容不多全是基本知识 用于学习事实地形 (Terrain LOD few small presentations for learning basic knowledge of all the fact that the terrain)

一个VRML的示例，通过鼠标点击可以使场景内的灯管发光(An example of a VRML through mouse clicks can make a scene inside the lamp light)

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.)

实现一个心行图案的各种二维几何变换（包括同比变换，错切变换，平移变换、旋转变换等）(achieve a mind trip of two-dimensional pictorial geometry transformation (including an transform, shear transformation, translation transform, ROTATION))

计算机图形学中的shadow mapping程序，与网上其他代码不同，作者实现了对带有纹理的场景的阴影绘制.(Shadow Mapping Code in Computer Graphics.And it s for textured scene.)

实现三维对象的平移,旋转变换,以及投影变换,不错的(Realize 3 d object of translation, rotation transformation and projection transformation, good)

dxf图转G代码工件软件，dxf读取过程清晰(DXF diagram to G code workpiece software, DXF read process is clear)

说明：  访问最底层LOD模型路径，打开后获取顶点数据和PirmitiveSet，重绘模型的三角面片(Visit the bottom LOD model path, open it, get vertex Array and PirmitiveSet, and redraw the triangle of the model.)
