Hi Matt, Use a combination of custom NodeVisitor to traverse the scene, and an osg::Drawable::ArrayFunctor to traverse the vertices. When you handle the Drawable's you can get the world transform by either accumulating the transform yourself during the NodeVisitor traversal or use osg::Node::getWorldMatrices() or osg::computeLocalToWorld(NodePath) using the NodeVisitor::getNodePath() for the node path.
