For my case, once a box is piled, there's no need to move the object, I can even regenerate the whole entity if a change is necessary (this is a CAD app. not a game). But I'm sure if someone needs both optimization and manipulation, there will be a little bit pain, he/she'll have to traverse to the point list and change the values.
By the way, I've been experiencing a strange situation here. Now I have two versions, both optimized and PAT free. The one with the Box shapes has twice as long Cull & Draw & GPU cycles; so I prefer the "visible faces only" version for now. But, if I don't run the osgUtil::Optimizer after regeneration, the visible only version has changing texture colors from pale to bright every now and then (that's the kind of behaviour when you don't set the 1,1,1,1 color for a textured face) Any ideas ? 2008/10/23 Mike Greene <[EMAIL PROTECTED]> > What happens if you need to periodically update size, position, orientation > of objects?
