L\u00e4gg till information om tillg\u00e5ngar i 3D.<\/strong><\/h2>\n

Metadata \u00e4r strukturerad information som beskriver, f\u00f6rklarar, lokaliserar eller g\u00f6r det l\u00e4ttare att h\u00e4mta, anv\u00e4nda eller hantera en informationsresurs. Aspose.3D for Java API har st\u00f6d f\u00f6r att definiera metadata f\u00f6r scenen.<\/p>\n

3D visar tillverkar stora m\u00e4ngder av metadata och bildinformation. Metadata \u00e4r en tillg\u00e5ng och en del av showen.<\/p>\n

  1. Initiera en 3D scen med Scene<\/code> klass.<\/li>\n
  2. Ange program\/verktygsnamn.<\/li>\n

  6. Spara 3D-scenen i det st\u00f6dda filformatet.<\/li>\n<\/ol>\n
