We ran into an interesting crash, caused by the fact that an update callback would set the update callback pointer of its node to NULL (causing it to be freed), before calling traverse on the node. It seems to me it should be possible to do a pre-order delete traversal, but this causes a crash.
This raises kind of an interesting question... how do you go about removing update callbacks from the scene? Since you can only modify a scene during the update traversal, it seems like you are forced into having update callbacks remove themselves, which leads to an unpleasant case of a "this" pointer deleting itself. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
