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.

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

     SoType		   SoDirLtGetClassTypeId()
	  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
     }
