GIS座标算法 非常的方便 -GIS coordinates of the algorithm is very convenient

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

一个电子地图的课程设计,其实还没做完,不过老师要求的功能都差不多实现了,打算在此基础上叠加地貌晕渲的,不过在三角剖分上遇到了些麻烦~,文件夹009中包含了数据的一部分,因为数据大概有十几M就只弄了一部分,还有一个属性数据库.及有些头文件-an electronic map of curriculum design, in fact not done, but teachers required functions are almost the intention on the basis of this superposition Hillshading, but the triangulation encountered a bit of trouble ~, 009 folder contains the data part, because there are about a dozen data M just get the part, there is an attribute database. and some of the first documents
