相机在轨道上沿轨道（管状）运动； 右键可以选择不同视角观察和退出，有两个视角；(Camera on the track along the orbit (tubular) movement Right you can choose a different perspective and exit, there are two perspectives )

说明：  读取obj的内容数据 利用opengl绘制出 obj格式的三维模型(Read and draw the three-dimensional model of obj format)

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.)

技术资料：总线地址、物理地址、虚拟地址相关概念澄清(Technical data: bus address, physical address, virtual address conceptual clarity)

用vrmlscript制作的三维场景绿化植树功能源代码及图片，用BS浏览器可查看，在控制台可以直接打印出生成的源代码，生成源代码可直接复制到场景中永久保存，相当于一个可视化的vrml绿化编辑器。(Produced by using three-dimensional scenes vrmlscript greening and tree planting function source code and pictures, with BS browser can view in the console can directly print out the generated source code to generate the source code can be directly copied to the permanent preservation of the scene, which is equivalent to a Visualization of VRML Green editor.)

说明：  该程序模拟了海浪的三维动态仿真，展示了随机海风作用下，波浪的运动。(The program simulates the three-dimensional dynamic simulation of ocean waves)

可以把jpg图片转换成obj三维网格文件，这样可以在三维形态下观察图像数据(Jpg images can be converted into three-dimensional grid obj file, so that patterns can be observed under the three-dimensional image data)

PLY文件的读取和写入程序：PLY文件是一个三维图形的数据存储格式，包括了三维曲面上所有采样点的坐标，以及所有采样点间的网络拓扑(A program which can read and write a PLY file)

实现lod和水面叠加的功能，并可以读入txt各式的水位文件(Lod achieve superposition and surface features, and can read a variety of water into the txt file)

在各种图形中，通过提取点的凹凸部分来鉴别曲线的特征，本节代码利用曲率关系分别提取凹点的个数，判断曲线的弯曲(In a variety of graphics, through the extraction point to identify curves convex-concave part of the characteristics of the code used in this section were extracted from concave curvature of the relationship between the number of points to determine the bending curve)
