ArcObjects实现图层控件代码(TOCCONTROL)

基于物理的大气效果实时绘制，利用查询表的方法，对颜色进行实时的计算查找，可以用于大型的仿真系统中-Physics-based real-time rendering of atmospheric effects, using look-up table method for calculating real-time color to find, can be used in large-scale simulation system

读取、显示、放缩shape文件的功能，支持小数据量的shp文件。 代码也是网上找到的，主要是给大家提供一个可行的方法和思路， 真正到应用阶段还需要很多改进。 我在vc6.0下测试过可以运行。-Read, display, zoom shape files, to support the small amount of data of the shp file. Code is found online, primarily to provide a viable solution and ideas to the application stage of the real needs many improvements. I tested vc6.0 can run under.
