Nasıl yapılır: 3B Görünümde Kamera Konumuna ve Yönüne Animasyon Ekleme

  • Makale

Aşağıdaki örnekte, bir kameranın konumuna animasyon ekleme ve 3B bir sahneyi işaret eden yöne animasyon ekleme işlemi gösterilmektedir. Bu, ve özelliklerine sırasıyla PerspectiveCameraanimasyon eklemek için Position ve LookDirection kullanılarak Point3DAnimationVector3DAnimation yapılır. Bir olaya yanıt olarak, bir sahnenin görünümünü değiştirmek için bunun gibi bir animasyon kullanabilirsiniz.
