تحديد خيارات حفظ ملف 3D

خيارات حفظ الملفات 3D

هناك العديد من الأحمال الزائدة لطريقة Scene.save التي تقبل كائن SaveOptions. يجب أن يكون هذا موضوعًا لفئة مشتقة من فئة SaveOptions. يحتوي كل تنسيق حفظ على فئة مناظرة تحتوي على خيارات حفظ لتنسيق الحفظ هذا ، على سبيل المثال ، هناك ColladaSaveOptions لتنسيق الحفظ FileFormat.Collada.
