A discussion came up this week about the overhead and memory consumption of various OSG objects, relating to the possible indiscriminate use of them. It turned out not to be an issue, but in the process of investigating, I quickly measured the in-memory byte sizes of a few common OSG objects. These are simply measured with sizeof(osg::Node) or the like. Obviously, in practical use, the containers and ref_ptrs involved increase the actual memory consumption, but this gives you a baseline idea.
