Bei der Arbeit an einem aktuellen Projekt ist ‘ganz nebenbei’ eine Portierung des Visicam Panorama VR Viewers von Papversion Version 1.5 auf Version 2.0 Great White angefallen.
Die ich natürlich nicht vorenthalten will, da dies auch anderen Suchenden zu Gute kommen könnte. Anzumerken sei noch, das ich die Integration der Texturen von Bitmaps auf Movieclips die vorher instanziert werden müssen gewandelt habe, um später noch clickbare Flächen hin zu zufügen.
Als Basis dient das Aktuelle Papervision3d 2.0 Pack (bitte per SVN ziehen) und ein FLA, bei dem die Baseclass den Namen ‘main’ hat. Desweiteren müssen in der Bibliothek noch die MovieClips front_mc, back_mc, left_mc, right_mc, top_mc und bottom_mc in für AS exportierter Form vorliegen.
