Der Holo-Viewer ist Ihr leistungsstarkes Werkzeug zum Betrachten von 3D-Modellen auf einer Vielzahl von Endgeräten. Er übernimmt die Echtzeit-Berechnung von Ansichten aus unterschiedlichen Blickwinkeln und stellt den Einfall des Lichts und die Darstellung von Schatten realitätsnah dar. Außerdem ermöglichen die meisten Endgeräte eine Interaktion mit der gezeigten 3D-Szene. Mit dem Holo- Viewer haben Sie ein Steuerwerkzeug für Interaktionen und Animationen, welches die virtuelle Welt noch näher an die Realität rückt. Der Holo-Viewer ist auf stationären, wie mobilen Geräten einsetzbar und somit ortsunabhängig. So haben Sie Ihre visualisierten CAD-Modelle immer und überall in der Tasche. Anwendungen finden sich im Bereich des Engineerings, z.B. in der Konstruktion in der Prototypenbewertung, Ausbildungstrainings mit 3D- Schulungsmaterial oder im Vertrieb von Maschinen und komplexen Anlagen. Der Holo- Viewer ermöglicht es dem Benutzer, Hologramme oder virtuelle Darstellungen von Prototypen schnell zu laden und zu präsentieren. Skalieren, verschieben, drehen und animieren Sie Ihre 3D- CAD Modelle oder Komponenten interaktiv. Präsentieren Sie Ihrem Kunden schon vor der Fertigstellung eine funktionierende Maschine oder aktivieren Sie den Multi-User-Modus und gehen Sie mit Ihren Kollegen zusammen auf eine virtuelle Entdeckungstour.
