Hi Steven, I'm not clear on what you are after. My only thought is perhaps the osgSim::VisibilityGroup is something like what you're after. You decorate a subgraph with a VisibilityGroup and only if the eye point is within a volume is the subgraph traversed. This is good for handling the contents of buildings which you only see once you are inside the outer skin of the building. From the include/osgSim/VisibilityGroup header:
/** VisibilityGroup renders (traverses) it's children only when the camera is inside a specified visibility volume. * The visibility volume is intersected with a line segment that extends from * the current camera's eye-point along the view vector for a given segment length. * If an intersection is detected then the node's children are traversed. */ Robert.
