All,
Does anyone have any experience using OSG with GL studio? We are having some
issues that we would like some input on. I wanted to place a general inquiry
before getting specific on the problem at hand.
Thanks,

In answer to your inquiry, I'm using a database based on
osgTerrain::TerrainTile so the texture settings are embedded in the tiles

Phanindra,
You'll need to build an OSG database from your .tif and dted content using
Virtual Planet Builder (VPB). Documentation is available on how to do this.
Once the database is built, you can either using osgViewer to browse the
database or you can write your own OSG app to fly through it.
All,
Is there a way of programmatically altering texture state such as filtering
on a chunk of terrain built with VPB?
Everything I've tried thus far has not worked.
Thanks in advance.

Robert,
I just read your reply after I had sent my email response to Chris. This
helps me understand why my approach wasn't working in the first place.
I will take your advice and explore this further. I will probably have more
questions as I proceed to find a solution to meet my needs...
All,
Is there a way to force an OSG window (osgViewer) to always be on top of all
the other windows being displayed?
Thanks in advance.

Just a follow up question on this, does QT allow a multi-threaded embedded
osgViewer or is it knocked down to single threaded like what happens to
osgViewer embedded in GLUT?
