Asset-Informationen zum 3D-Dokument hinzuf\u00fcgen<\/strong><\/h2>\n

Metadaten sind strukturierte Informationen, die das Abrufen, Verwenden oder Verwalten einer Informations ressource beschreiben, erkl\u00e4ren, lokalisieren oder erleichtern. Aspose.3D for Java API bietet Unterst\u00fctzung f\u00fcr die Definition von Metadaten f\u00fcr die Szene.<\/p>\n

Definieren Sie eine Metadaten f\u00fcr die Szene<\/strong><\/h3>\n

3D Shows erzeugen riesige Mengen an Metadaten und Bild informationen. Metadaten sind ein Aktiv posten und Teil der Show.<\/p>\n

    \n
  1. Initial isieren Sie eine 3D-Szene mit der Scene<\/code>-Klasse.<\/li>\n
  2. Legen Sie den Namen der Anwendung\/des Werkzeugs fest.<\/li>\n
  3. Legen Sie den Namen des Anwendungs-\/Werkzeug herstellers fest.<\/li>\n
  4. Ma\u00dfeinheit einstellen.<\/li>\n
  5. Ma\u00dfeinheit Skalierung faktor festlegen.<\/li>\n
  6. Speichern Sie die 3D-Szene im unterst\u00fctzten Dateiformat.<\/li>\n<\/ol>\n

    In diesem Beispiel nehmen wir an, dass die Szene von einem CAD-Tool namens “Egypt” erstellt wurde und von “Manualdesk” entworfen wurde:<\/p>\n
