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