Aggiungi informazioni sull’asset al documento 3D<\/strong><\/h2>\n

I metadati sono informazioni strutturate che descrivono, spiegano, individuano o semplificano il recupero, l’utilizzo o la gestione di una risorsa di informazioni. Aspose.3D for Java API supporta la definizione dei Metadati per la scena.<\/p>\n

Definire un metadato per la scena<\/strong><\/h3>\n

3D mostra la produzione di enormi quantit\u00e0 di metadati e informazioni sull’immagine. I metadati sono una risorsa e fanno parte dello spettacolo.<\/p>\n

    \n
  1. Inizializza una scena 3D utilizzando la classe Scene<\/code>.<\/li>\n
  2. Imposta il nome dell’applicazione\/strumento.<\/li>\n
  3. Imposta il nome del fornitore dell’applicazione\/strumento.<\/li>\n
  4. Impostare l’unit\u00e0 di misura.<\/li>\n
  5. Impostare il fattore di scala dell’unit\u00e0 di misura.<\/li>\n
  6. Salva 3D scena nel formato file supportato.<\/li>\n<\/ol>\n

    In questo esempio, supponiamo che la scena sia creata da uno strumento CAD chiamato “Egitto” ed \u00e8 progettata da Manualdesk:<\/p>\n
