You've got me interested in this, I'm probably going to need something similar for the stuff I'm doing at some point. -- http://www.ssTk.co.uk _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
