Hi Zach,
Are you setting the graphics context ID when you create your viewer? I
was observing similar symptoms until I explicitly did so. I just added
this line after SceneView creation:
sceneView->getState()->setContextID(osg::GraphicsContext::createNewConte
xtID());
This will work around the problem but not solve it.
These two methods in SceneView are what you need to call.
/** Release all OpenGL objects from the scene graph, such as
texture objects, display lists etc.
* These released scene graphs placed in the respective
delete GLObjects cache, which
* then need to be deleted in OpenGL by
SceneView::flushAllDeleteGLObjects(). */
virtual void releaseAllGLObjects();
/** Flush all deleted OpenGL objects, such as texture objects,
display lists etc.*/
virtual void flushAllDeletedGLObjects();
osgProducer::Viewer should call these if one calls :
viewer.sync();
viewer.cleanup_frame();
Before you close down the viewers render surfaces. The osgviewer
example does this just after the exit of the main loop.
A quick glance at the code now suggests that this is all that one
should need to, it should then be perfectly ok to re-create the
graphics windows afterwards.
Robert.
