在MC（Marching Cubes）算法中,考虑了二义性的问题，是一个很好的程序(MC (Marching Cubes) algorithm, consider the ambiguity problem, it is a good program)

A 3D aplication in Pure VB

电视系统中，进行需要在线调整Gamma曲线，此工具可以方便的对电视系统中的Gamma曲线读写，修改，该软件使用了贝塞尔曲线，方便的拖出你想要的曲线，然后在线升级(TV system, to adjust the Gamma curve need to be online, this tool can be easily against the television system in the Gamma curve to read and write, modify, the software uses the Bezier curves, a convenient pulled out the curve you want, and then Online Upgrade)

给出了迭代函数系统生成Julia集的代码(In this paper, a iterative function system redraw Julia program source code)

OSG实例，shader编程，实现简单的小溪河流定向移动(OSG , shader programming, achieve a simple directional movement of rivers )

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.)

Visual C++结合OpenGL做的一个3D场景。其中包含地形生成，场景漫游，碰撞检测，场景中模拟了河流，跳跃的鱼，喷泉，树木，水草，房屋，塔楼，楼梯，飘动的旗帜等等。第一人称视角，可以跳跃行走碰撞检测，模拟了白天黑夜等等！(Visual C++ with OpenGL to do a 3D scene. Which contains the terrain generation, scene roaming, collision detection, simulation of the river scene, jumping fish, fountains, trees, plants, houses, towers, stairs, waving flags and so on. First-person perspective, you can skip walking collision detection, simulation of the day and night, and more!)

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)

利用分形和混沌理论，生成十分精美的2维图形。有多种参数可以对图形进行控制。(use fractal and chaos theory, generate very attractive two-dimensional graphics. A number of parameters can control graphics.)
