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.

METHODS

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

     static SoType       getClassTypeId()
          Returns type identifier for this class.

ACTION BEHAVIOR

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

FILE FORMAT/DEFAULTS

       NormalBinding {
          value  PER_VERTEX_INDEXED
     }
