一个完善的读取3DS文件例子，可以在3DS MAX文件中建立的三维模型直接用于VC++中-A perfect example to read 3DS file

分析读取Bundler输出的.txt,.key文件，对三维点云sift特征建立KD树索引。-Parsing Bundler Output including .txt& .key Files to construct a KD tree Index.

用3d建模工具建好三维模型后，导出为mesh文件，本程序就是把3d mesh转换为高度图，从而为读取高度图建立三维模型打下基础，实现加速显示的目标。-3d modeling tool built with three-dimensional model, export mesh file, the program is to 3d mesh into a high figure, so as to read a three-dimensional model of a high figure t
