 * 3D Starter:

 * Create a 3D model and load it into a U3D annotation.

 *

 * Define a 3D view and load some 3D data with the view defined. Then create

 * an annotation containing the loaded 3D data with the defined 3D view as the

 * initial view.

 *

 * Acrobat 7.07 or above is required for viewing PDF documents containing a

 * 3D model.

 *

 * Required software: PDFlib/PDFlib+PDI/PPS 7.0.1

 * Required data: U3D data file
