/**
 * The GeometryInfo object holds data for processing by the Java3D geometry
 * utility tools.<p><blockquote>
 *
 *         The NormalGenerator adds normals to geometry without normals.<p>
 *
 *         The Stripifier combines adjacent triangles into triangle strips for
 *         more efficent rendering.<p></blockquote>
 *
 * Also, the GeometryCompressor can take a set of GeometryInfo objects in a
 * CompressionSteam and generate a CompressedGeometry object from the
 * geometry.<p>
 *         Geometry is loaded into a GeometryInfo in a manner similar to the
 * <a href="../../../../../javax/media/j3d/GeometryArray.html">
 * GeometryArray</a> methods.  The constructor for the GeometryInfo takes a flag
 * that specifies the kind of data being loaded.  The vertex data is
 * specified using methods that are similar to the GeometryArray methods, but
 * with fewer variations.<p>
 *         The major difference between GeometryInfo and GeometryArray is
 * that the number of vertices, vertex format, and other data are specified
 * implictly, rather than as part of the constructor.  The number of verticies
 * comes from the number of coordinates passed to the setCoordinates()
 * method.  The format comes from the set of data components that are
 * specified.  For example, calling the setCoordinates(), setColors3() and
 * setTextureCoordinatesParames(1, 2) methods implies a
 * format of COORDINATES | COLOR_3
 * | TEXTURE_COORDINATE_2.  Indexed representation is specified by calling
 * the methods that specify the indices, for example
 * setCoordinateIndices().<p>
 *         Stripped primitives are loaded using the TRIANGLE_FAN_ARRAY or
 * TRIANGLE_STRIP_ARRAY flags to the constructor.  The setStripCounts()
 * method specifies the length of each strip.<p>
 *         A set of complex polygons is loaded using the POLYGON_ARRAY
 * flag to the constructor.  The setStripCounts() method specifies the length
 * of each contour of the polygons.  The setContourCounts() method specifies
 * the number of countours in each polygon. For example, a triangle with a
 * triangular hole would have strip counts [3, 3] (indicating two contours of
 * three points) and contour counts [2] (indicating a single polygon with two
 * contours).<p>
 *         GeometryInfo itelf contains some simple utilities, such as
 * calculating indices for non-indexed data ("indexifying") and getting rid
 * of unused data in your indexed geometry ("compacting").<p>
 *         The geometry utility tools modify the contents of the
 * GeometryInfo.  After processing, the resulting geometry can be extracted
 * from the GeometryInfo by calling getGeometryArray().  If multiple tools
 * are used, the order of processing should be: generate normals, then
 * stripify.  For example, to convert a general mesh of polygons without
 * normals into an optimized mesh call:
 * <pre><blockquote>
 *         GeometryInfo gi = new GeometryInfo(GeometryInfo.POLYGON_ARRAY);
 *         // initialize the geometry info here
 *         // generate normals
 *         NormalGenerator ng = new NormalGenerator();
 *         ng.generateNormals(gi);
 *         // stripify
 *         Stripifier st = new Stripifier();
 *         st.stripify(gi);
 *         GeometryArray result = gi.getGeometryArray();
 * </blockquote></pre>
