The node whose visibility is to be tested.
A node defining a point of view, as used by the
YES if the bounding box of the tested node intersects the view frustum defined by the
point node; otherwise,
Any node containing a camera or spotlight may serve as a point of view (see the
point property for details). Such a node defines a viewing frustum—a portion of the scene’s coordinate space, shaped like a truncated pyramid, that encloses all points visible from that point of view.
Use this method to test whether a node lies within the viewing frustum defined by another node (which may or may not be the scene renderer’s current
point node). For example, in a game scene containing multiple camera nodes, you could use this method to determine which camera is currently best for viewing a moving player character.
Note that this method does not perform occlusion testing. That is, it returns
YES if the tested node lies within the specified viewing frustum regardless of whether that node’s contents are obscured by other geometry.
