Obviously it's a good idea to remove stuff on exit to avoid memory leaks. You *could* just leave your scene as it is and let OSG clean it up when the viewer exits - but I like to follow the principle of: whoever creates an object should be responsible for removing it ;) > > Also something that seems a bit odd - why an in scene graph Camera has > a GraphicsContext assigned to it.

I thought that would be equivalent to just leaving the GraphicsContext as NULL and letting it inherit, I didn't realize there might be side effects to explicitely setting the GraphicsContext. Thanks for this note, now I have a better understanding of what Camera::setGraphicsContext actually does :) So I guess we have at least 3 different workarounds then: - Leave the camera's GraphicsContext as NULL - Remove the Camera's children before removing the Camera - Wait for the graphics thread to finish (i.e. stop viewer threading) before removing the camera ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=68393#68393 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
