Why are using using MyOrthoImage.tif as a DEM?
BTW, as an experiment just set the -l value to something like 4, this
will build the database very quickly and you then can check the
result.
With the SVN version of VPB, one useful thing you can do is write all
the osgdem options to a VPB source file, and then this source file in
subsequent runs, this makes means you can avoid all the long winded
options when you are experimenting. i.e
// Create the build.source file
osgdem --bluemarble-west -t ../land_shallow_topo_west.tif \
--bluemarble-east -t ../land_shallow_topo_east.tif \
--geocentric \
-o earth/earth.ive \
--so build.source
// run the build
osgdem -s build.source
// have a look at the file - it's just an extended form of a .osg file
cat build.source
// override the number of levels
osgdem -s build.source -l 4
// run build adding your extra imagery
osgdem -s build.source -t MyOrthoImage.tif
To speed up the build you could also try using the --terrain option to
get osgdem to build an osgTerrain based tiles, this is results in much
quicker builds.
Also note that I added a directory name to the -o output path, i.e. -o
earth/earth.ive, this is a new feature that makes it eaier to keep
things a bit cleaner.
Also you'll find linux much faster at doing builds than windows, this
is down to better compilers and file systems, so if you are serious
about doing really big builds I'd recommend creating linux machine or
cluster.
Robert.
