opengl2.0.zip:opengl2。0开发包 我从网上下载的，供大家学习

介绍了两种投影变化及其相关的函数,可以清楚看出这两种变化的差别-introduced two projectors and related changes in the function, it can be clearly seen that the difference between the two changes

粒子系统。粒子的生命，颜色，衰减等的模拟。以及向外发散的效果。-Particle system. Particles of life, color, attenuation of the simulation. As well as the outward divergent results.

一个有关OpenGL的源代码，还是比较有用的，里面的代码相当详尽，对于OPENGL的使用方面有较大帮助，俺花了大规模时间来开发的呀，呵呵 望大家一起学习改进-one of the OpenGL source code, it is still useful, inside the code in considerable detail, the use of OpenGL for a greater help, I spent a large-scale development time to it, huh hope we will study together to improve

这是一个关于OpenGL的漫游天地的程序,可心用键盘的四个方向来控制背景的图像的漫游显示-This is a heaven and earth on the OpenGL roaming procedure, Kexin use the keyboard to control the direction of the four background images display roaming

this OPENGL program, it can be run on VC6.0+opengl-this is OPENGL program, it can be run on VC6.0+opengl

在进行数据比较或者演示时，一个形象的图表不但非常直观，而且也很生动。本实例介绍如何在Delphi中设计形象的三维饼图。 　　向窗体上添加一个TVtChart组件和一个TTimer组件，其中TVtChart组件用于显示饼图，而TTimer组件用于不停地改变饼图的数据，获得动态的效果 -In the comparison of data or presentation, a chart image is not only very intuitive, but also very lively. Examples of how the introduction of the Delphi to design the image of three-dimensional pie chart. To add a TVtChart form components and a TTimer components, including components used to display TVtChart pie, and TTimer components continuously change the pie chart for the data, access to dynamic effects

opengl实现的一个太阳系系统，可以通过界面来控制各个星球运转的速度。交互性比较好。-opengl achieved a solar system, can interface to control the operation of all the speed planet. Interactive is good.

应用背景通过给定的DEM数据进行地形绘制，利用OpenGL来实现绘制并且通过漫游实现对地形的实时性的生成以及浏览。利用LOD技术实现多分辨率的地形生成。关键技术关键技术是采用OpenGL中的函数首先对DEM数据进行绘制，在绘制之后通过纹理贴图让绘制好的地形变得真实，然后通过LOD技术使地形的漫游更加逼真

原代码下载，我对计算机图形学的编程实践，包括画直线、反走样直线、画圆、 画椭圆、画矩形、画多边形、矩形填充、多边形填充、3D变换、光照、贴图等。由于 精力有限，未对原码做任何注释。出于简化编程的考虑，许多地方指定了常数，未做 通用处理-download the original code, the computer graphics programming practice, including painting line, anti-aliasing straight Circle, painted oval, rectangular painting, drawing polygon, rectangle filling, polygon filling, 3D transformation, lighting, textures, etc.. Because of the limited energy, the original code did not make any notes. To simplify programming for consideration, in many places designated constant, declined to address GM
