HI Ferdi, The osgUtil::Simplifier wasn't designed to handle really large meshes, so there are no special schemes to doing the simplifier incrementally. The class makes extensive use of std contains like std::set/map so memory consumption won't be too linear, but shouldn't be exponential so it should be possible to handle large meshes given enough memory.
You could probably use the Simplifier is you broke your data up into more manageable chunks. It wouldn't be elegant, but it could well be a viable workaround. Robert.
