//! defines a ShapeHints node of VRML specifying properties of geometry and its appearance. <br>
//! The ShapeHints node indicates that IndexedFaceSets are solid, contain ordered vertices, or <br>
//! contain convex faces. <br>
//! These hints allow VRML implementations to optimize certain rendering features. <br>
//! Optimizations that may be performed include enabling back-face culling and disabling <br>
//! two-sided lighting. For example, if an object is solid and has ordered vertices, an <br>
//! implementation may turn on backface culling and turn off two-sided lighting. To ensure <br>
//! that an IndexedFaceSet can be viewed from either direction, set shapeType to be <br>
//! UNKNOWN_SHAPE_TYPE. <br>
//! If you know that your shapes are closed and will alwsys be viewed from the outside, set <br>
//! vertexOrdering to be either CLOCKWISE or COUNTERCLOCKWISE (depending on <br>
//! how you built your object), and set shapeType to be SOLID. Placing this near the top of <br>
//! your VRML file will allow the scene to be rendered much faster. <br>
//! The ShapeHints node also affects how default normals are generated. When an <br>
//! IndexedFaceSet has to generate default normals, it uses the creaseAngle field to determine <br>
//! which edges should be smoothly shaded and which ones should have a sharp crease. The <br>
//! crease angle is the angle between surface normals on adjacent polygons. For example, a <br>
//! crease angle of .5 radians (the default value) means that an edge between two adjacent <br>
//! polygonal faces will be smooth shaded if the normals to the two faces form an angle that is <br>
//! less than .5 radians (about 30 degrees). Otherwise, it will be faceted. <br>
