Hi, you may use a PolytopeIntersector to get all items intersecting the rectangle. Afterwards, you may modify the node mask of the found items: set a specific bit of the node mask to one if it is found by the PolytopeIntersector and to zero if not (by implementing a visitor inspecting the scene). The camera will then cull all items that have a zero in the node mask.
You may also write your own visitor that is doing this checking and sets the node mask of the visited drawables at the same time.
