)" bezog sich darauf, dass es für OBJ eben zufällig (weil es so einfach und so weit verbreitet ist) einen Loader gibt, aber für andere Formate eben nicht - und nicht zuletzt auch darauf, dass du nicht gesagt hast, um welches Format es geht. Es gibt hunderte oder sogar tausende von "Dateiformaten für 3D-Daten", oft sehr speziell, und manchmal sehr komplex (mit Animationen oder komplexen Materialien, Bezierflächen etc...). Für VRML gibt es in Java3D glaub' ich auch schon einen, aber ... für "irgendein" anderes Format kommt bei der Implementierung dieser lapidar hingeschriebenen "loadSomethingElseThanAnOBJ" eben u.U. viel Arbeit auf dich zu... Also... um welches Format geht es?
