| This node defines a point light source at a fixed 3D location. |
| A point source illuminates equally in all directions; that is, it is omni-directional. |
| A light node defines an illumination source that may affect subsequent shapes in the scene graph, depending on the current lighting style. |
| Light sources are as you should expect affected by the current transformation. |
| A light node under a separator does not affect any objects outside that separator. |
