l3dview is used to render a l3dset. You can specify camera, background and fog for each l3dview.Every l3dset has one default l3dview, which cannot be deleted. Additionally you can register more l3dviews which are processed before/after the default views.The l3dnodes can be made visible only to certain cameras. By default they are visible to the default camera and windowsized.
Another special purpose of l3dviews is rendering to a texture.
