org.j3d.aviatrix3d.Viewpoint
A viewpoint into the scene.
Viewpoints have their own implicit directional light (a headlight) that is controlled separately to the normal in-scenegraph lights. Lights are scoped by default and thus having the viewpoint also have a light following it around is a pain to deal with, you can select on directly on the viewpoint itself. This light is always pointing down the Z axis in the local coordinate system.
