Try using the --TERRAIN option in the osgdem command to see if that makes a difference in your build times...

I compile gdal and VPB and rightly get all the files with VS2005. When I use osgdem to generate DEM, I find it generates .IVE and a folder of XXX-_root_L0_X0_Y0 . The problem is: It takes too long to generate the DEM. I check the time of file genration time and find the intervals between first several file is very short for level 0, level 1 and level 2. Coming to level 3 and after, the intervals are long, in my case 2 minutes or 3 minutes. So, after one and a half days, the DEM is only generated half. The input files are : Texture is: texture.tilf 70m 4019*4284 ; DEM is: height.tif 47m 4019*4284. The comand line to generate DEM is : osgdem -t texture.tif -d height.tif -l 8 -a mydem.osga Anybady can help me? Thanks a lot. 2011-05-28 ________________________________ ijustfu _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
