osgEarth 1.2-RC1 is available and ready for testing!
This the first release candidate for Version 1.2, which we hope to officially tag in the first week of August. If you're an osgEarth user, please test now against the head SVN revision and please report any issues.
osgEarth is an OpenSceneGraph toolkit renders terrain models dynamically at run time. Instead of pre-generating a terrain model offline and then loading it into OSG, you can point osgEarth at your raw data sources and it will produce a terrain model on the fly.

sorry for my unclear expression.
my issue is:
when executed the function setViewpoint(), camera fly to the specific viewpoint.
then, click left-mouse-button, camera will jump to the surface of the terrain immediately.
