As Robert mentions, this has all been discussed extensively before. I was in on that discussion, about 2 years ago. Someone had proposed a pretty decent system that worked almost exactly like this, I think. Ahh, here it is. Ulrich was involved then too: http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2009-November/035629.html I think a facility like this is extremely useful, and would like to see it move forward. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.
