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.
