The scenegraph keeps a bounding volume of every Node for its own
purposes anyway. You can access it using
DynamicVolume &vol = node->getVolume(true);
Note that this volume is in the local coordinate frame of the Node. For
collision detection you probably want the bounding volume in a global
(world) coordinate frame (to compare them against each other). You can
get this from the system using
DynamicVolume world_vol;
node->getWorldVolume(world_vol);
Hope it helps
