You can try one of the following: osgEarth (http://www.osgearth.org) Virtual Planet Builder ( http://www.openscenegraph.org/projects/VirtualPlanetBuilder) Either will produce a textured terrain model that you can use the OSG manipulators (or your own custom code) to navigate. Glenn Waldron : P

Hi, TBH, I thought including a physics engine for the project was overkill, since the objective was pretty simple. Now, that you've mentioned, I wouldn't mind trying it out, but I am not sure how well integrated is Bullet/ODE with osg. Also, is there any documentation that would help me identi

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. T

Hi Nick, The OSG allows you to assign different graphics contexts to different cards, but sharing GL objects can't be done at the level you are after as the graphics driver and hardware all won't be able work that way. To share the data of the RTT card you'll need to use a double buffered PBO to
