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
     }
