Hi all,
are there any special steps involved to unload a PagedLOD database?
What I want to do is release the main memory and OpenGL resources associated
with a PagedLOD.
My setup is roughtly the following:
- osgViewer::Viewer in single-threaded mode
- rendering is triggered on-demand by calling 'viewer->frame()'
- osg::Group* sceneNode and osg::Node* modelNode (both as osg::ref_ptr)
- to release the model I call sceneNode->removeChild(modelNode) and then set
modelNode = 0 to invalidate the ref_ptr
- after that the frame draw is not triggered anymore.
This works *most* of the times but I sporadicly get a crash in osgTerrain::traverse which
appears like there is some thread still running on the database.
Cheers,
/ulrich
