 * 3D Starter:

 * Load a 3D model and create a 3D annotation from it.

 *

 * 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 9 or above is required for viewing PDF documents containing a

 * PRC 3D model.

 *

 * Required software: PDFlib/PDFlib+PDI/PPS 9

 * Required data: PRC data file
