Hi Alberto, There is no automated tool for split geometry up. Rather the opposite - in the osgUtil::Optimizer then is passes there merge geometry for the purposes of improving performance :-)
For different models there will be different sweet spots for scene graph granularity. In general graphic hardware these days copes very well with high polygon counts so coarser grained is often best, but not too coarse grained though... but whats the sweet spot... ooh database dependent again :-) Good performance benchmarking procedures is critical to answer the question of what the sweet spots might be.

Detouring a bit the topic from culling occluded objects to frustum-culling objects: Is there any common procedure (with OSG) to split large objects in smaller pieces in order to increase the performance of the frustum culling? I'm not thinking here about terrain objects, but any kind of object as buildings, parts of machinery... that can be "broken" into pieces so I can later make an octree scene from them. I don't think it is a hard task to do myself, but I prefer to ask first to see if it is already done :) Alberto _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
