Thank you guys for your replies. You see, I have to setup 3 screens - one

Both VPB and osgEarth use GDAL under the hood to read heightfield data. So
either: use one of the GDAL-supported formats (
http://www.gdal.org/formats_list.html) that matches your data type, or
transform your data into one of those formats. Then either VPB or osgEarth

I am thinking to put all the data in the same node (not column by column). I

Hi,
We did some tests with SLI as well, GeForce 285. We had a single screen and
a way to expensive shader on a single quad. Just to be sure the CPU wasn't
the bottleneck. Worked like a charm. Frame rate doubled when we enabled SLI

Correction. There is no difference between GL1/2 and GL3 -- they are

Hi Filip,
check your system.log-file -- I am pretty sure the osgdb_obj pluging
refers to the osg-dylibs in /usr/lib or similar.
You'll have to massage the paths to the libs stored in the plugin via
install_name_tool in a post-build-step.
Paths to libs are hardcoded in the object-file when linked

Hi Harold,
The most likely issue is that you are running the view multi-threaded,

this and you'll prevent the next frame from advancing before it's
