One thing you should check is if you have any raw C++ pointers pointing to objects that are also pointed to by ref_ptr's. Accessing the object through the raw pointer after that the ref_ptr's have gone out of scope is illegal since the object is automaticly destroyed when the last ref_ptr goes out of scope. Notice that since OSG uses ref_ptr's in most places any object that you add to a scenegraph will most likely be referenced by a ref_ptr. You should therefore try to avoid using raw pointers to such objects. It's safer to use ref_ptr's. Example: the following will fail Code: osg::Node* myTransform = new osg::MatrixTransform(); { osg::ref_ptr< osg::Group > myGroup = new osg::Group(); myGroup->addChild(myTransform); } myTransform->someMethod(); // Wrong. Object has been deleted. In the example above replace the first line with: Code: osg::ref_ptr< osg::Node > myTransform = new osg::MatrixTransform(); and use myTransform.get() inside the addChild call. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=23809#23809 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
