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