Robert, Thanks a lot for your quick answer!
I understand the design difference you mentioni and it is relevant. Now from my readings of the beginners' guide, I understood that callbacks were needed to enforce thread safety. Your answer suggests that it is not the case. Can you confirm? i.e. do you confirm I can modify the OSG objects in a direct way (without callbacks) before calling Viewer::frame() and expect a correct rendering behavior? Kind regards, Antoine. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=71459#71459 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
