Snow world, realize the 3

光照和键盘控制: 添加光照和键盘控制，它让程序看起来更美观。 -Learning how to texture map has many benefits. Lets say you wanted a missile to fly across the screen. Up until this tutorial we d probably make the entire missile out of polygons, and fancy colors. With texture mapping, you can take a real picture of a missile and make the picture fly across the screen. Which do you think will look better? A photograph or an object made up of triangles and squares? By using texture mapping, not only will it look better, but your program will run faster. The texture mapped missile would only be one quad moving across the screen. A missile made out of polygons could be made up of hundreds or thousands of polygons. The single texture mapped quad will use alot less processing power.

检查某一点是否位于平截头体内，并据此决定是否显示。用dev-c++编译。-check whether a certain point in the first-cut body, and accordingly decide whether to show. With dev- c compiler.

自制的基于MFC、OpenGL平台的平面二维坐标图程序，支持拖动平移、滚轮缩放和窗口缩放等功能，支持大数据量绘图。程序在VC6.0下编译通过。

本代码主要适合OpenGL的初学者，对一些纹理测试的理解。

一本非常好的OpenGL入门书籍，通过这本书可以快速入门，掌握基本的操作。-OpenGL is a good entry-books, this book can be through the Quick Start, to master the basic operation.

使用鼠标动态绘制直线，以及将屏幕坐标转换为OpenGL坐标。-use a mouse linear dynamic mapping, and to coordinate conversion to the screen coordinates of OpenGL.

用于多幅重复边缘图像的拼接，可以自动对多幅图像的重复边缘进行匹配，删除图像冗余信息，实现多张图像的拼接，用于将多幅图像合成一幅图像

在OpenGL视图中绘制三维物体-view of the OpenGL 3D Rendering

这个程序是用glut库编写的。我使用texturez使它对用户更具主动性。原则是矩阵。
