[osg-users] animation in SceneView vs. Viewer??

[Robert Osfield]

Hi Abe,

I don't know what might be up given your code fragment. SceneView is
lower level that osgViewer::Viewer, so does require more care with
setup, and its less powerful....

Personally I wouldn't recommend using SceneView in your own code, just
use osgViewer::Viewer and its embedded mode if you need to integrate
with an existing window.   It's a waste of our time to struggle on
trying to get SceneView do things that Viewer already does out of the
box perfectly.

Robert.
