0027 //! defines a NormalBinding node of VRML specifying properties of geometry
0028 //! and its appearance.
0029 //! This node specifies how the current normals are bound to shapes that follow in the scene
0030 //! graph. Each shape node may interpret bindings differently.
0031 //! The bindings for faces and vertices are meaningful only for shapes that are made from
0032 //! faces and vertices. Similarly, the indexed bindings are only used by the shapes that allow
0033 //! indexing. For bindings that require multiple normals, be sure to have at least as many
0034 //! normals defined as are necessary; otherwise, errors will occur.
