0029 //! defines a Normal node of VRML specifying properties of geometry
0030 //! and its appearance.
0031 //! This node defines a set of 3D surface normal vectors to be used by vertex-based shape
0032 //! nodes (IndexedFaceSet, IndexedLineSet, PointSet) that follow it in the scene graph. This
0033 //! node does not produce a visible result during rendering; it simply replaces the current
0034 //! normals in the rendering state for subsequent nodes to use. This node contains one
0035 //! multiple-valued field that contains the normal vectors.
