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
     }
