DESCRIPTION

       This  node  defines  a  directional  light  source  that  illuminates  along  rays  parallel  to  a given
       3-dimensional vector.

FIELDS

     SoSFVec3f           direction
          Illumination direction vector.

METHODS

                         SoDirectionalLight()
          Creates a directional light source node with default settings.

     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. The  light's  direction  is  affected  by  the  current
          transformation.

FILE FORMAT/DEFAULTS

       DirectionalLight {
          on         TRUE
          intensity  1
          color      1 1 1
          direction  0 0 -1
     }
