PDFlib サンプル集(クックブック)
PDFlib で、3D モデルを作成し、U3D アニメーションにロードするサンプルプログラムです。
3D ビューを定義して、定義した 3D ビューを使っていくつかの 3D をロードします。初期ビューとして定義した 3D で 3D データをロードし、含めることでアニメーションを作成します。3D モデルを含んだ PDF を参照するには、Acrobat 7.07 以降が必要です。
/*
* 3D Starter:
* Load a PRC 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
