VPB测试 使用Osgdem运行例子

1.Osgdem运行例子所需数据下载地址：

http://www.cc.gatech.edu/projects/large_models/ps.html

Download Elevation Map: 16385 × 16385 PNG: 188MB 
Download Texture Map: 16384 × 16384 PNG: 268MB

2.GDAL对高程数据和影像数据格式化处理：

3.使用osgdem命令生成模型文件

osgdem --xx 10 --yy 10 -t ps_texture_16k.tif \ 

--xx 10 --yy 10 -d ps_height_16k.tif \ 

-l 8 -v 0.1 -o puget.ive -a pegout.osga
