DESCRIPTION
       SoLight	is  the	 abstract base class for all light nodes. 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
       affected	by the current transformation. A light node under a  separator
       does not	affect any objects outside that	separator.

       You  can	 also use a node kit to	create a light;	see the	reference page
       for SoLightKit.

FIELDS
     SoSFBool		 on
	  Determines whether the source	is active or inactive. When  inactive,
	  the source does not illuminate at all.

     SoSFFloat		 intensity
	  Illumination	intensity of light source. Valid values	range from 0.0
	  (no illumination) to 1.0 (maximum illumination).

     SoSFColor		 color
	  Light	source illumination color.

METHODS
     static SoType	 getClassTypeId()
	  Returns type identifier for this class.

ACTION BEHAVIOR
       SoGLRenderAction
	  Activates this light (if so specified) during	traversal.  All	 shape
	  nodes	 that come after this light in the scene graph are illuminated
	  by this light.

FILE FORMAT/DEFAULTS
       This is an abstract class. See the reference page of  a	derived	 class
       for the format and default values.

SEE ALSO
       SoDirectionalLight,  SoEnvironment,  SoLightKit,	 SoLightModel, SoMate-
       rial, SoPointLight, SoSpotLight
