DESCRIPTION
     This node specifies how the current normals are bound to shapes that
     follow in the scene graph. Each shape node may interpret bindings
     differently.

     The bindings for faces and vertices are meaningful only for shapes that
     are made from faces and vertices. Similarly, the indexed bindings are
     only used by the shapes that allow indexing. For bindings that require
     multiple normals, be sure to have at least as many normals defined as are
     necessary; otherwise, errors will occur.

FIELDS
     SoSFEnum		 value
	  Specifies how to bind normals to shapes.

FUNCTIONS
     SoNormalBinding *	 SoNormBindCreate()
	  Creates a normal binding node with default settings.

     SoType		 SoNormBindGetClassTypeId()
	  Returns type identifier for this class.

ACTION BEHAVIOR
     SoGLRenderAction, SoCallbackAction, SoRayPickAction
	  Sets the current normal binding type.

FILE FORMAT/DEFAULTS

	  value	 PER_VERTEX_INDEXED
     }
