Hello, Zachary. I use cow.osg for most of my testing. It may not be the most intensive geometry, but it seems to work for testing simple behaviors.
Try searching the OSG archives for "paintEngine". You should find a fix that MIGHT help with what you're seeing. Under Microsoft Windows, there appears to be a refresh problem requiring the paintEngine tweak. I don't know what impact it may have for Ubuntu. AdapterWidget versus QOSGWidget: I could be wrong, but I believe using AdapterWidget restricts osgViewer to single threaded mode, whereas QOSGWidget is supposed to allow single OR multithreaded modes. I hope this helps... D.J. On Wed, May 26, 2010 at 3:29 PM, Zachary Hilbun <[email protected]> wrote: > Hi, > > I'm using Eclipse with the Qt plugin in order to develop c++ osg code under > Ubuntu.
