+/**
+ * The Shape3D leaf node specifies all geometric objects.  It contains
+ * a list of one or more Geometry component objects and a single
+ * Appearance component object.  The geometry objects define the shape
+ * node's geometric data.  The appearance object specifies that
+ * object's appearance attributes, including color, material, texture,
+ * and so on.
+ * <p>
+ * The list of geometry objects must all be of the same equivalence
+ * class, that is, the same basic type of primitive.  For subclasses
+ * of GeometryArray, all point objects are equivalent, all line
+ * objects are equivalent, and all polygon objects are equivalent.
+ * For other subclasses of Geometry, only objects of the same
+ * subclass are equivalent.  The equivalence classes are as follows:
+ * <ul>
+ * <li>GeometryArray (point): [Indexed]PointArray</li>
+ * <li>GeometryArray (line): [Indexed]{LineArray, LineStripArray}</li>
+ * <li>GeometryArray (polygon): [Indexed]{TriangleArray, TriangleStripArray,
+ * TriangleFanArray, QuadArray}</li>
+ * <li>CompressedGeometry</li>
+ * <li>Raster</li>
+ * <li>Text3D</li>
+ * </ul>
+ * <p>
+ * When Shape3D is used with multiple geometry components, Java 3D may
+ * choose to use individual geometry bounds instead of the shape's
+ * bounds for region of influence operations, such as lighting.
+ * For example, the individual characters of a Text3D shape object
+ * may be rendered with a different light set.
