Arkit场景中的PanGesture和对象转换问题(Xamarin)

using ARKit;
using UIKit;

public class ViewController : UIViewController, IARSCNViewDelegate
{
    private ARSCNView sceneView;
    private SCNNode virtualObject;

    public override void ViewDidLoad()
    {
        base.ViewDidLoad();

        sceneView = new ARSCNView(View.Bounds);
        sceneView.Delegate = this;
        View.AddSubview(sceneView);

        // 创建虚拟对象
        virtualObject = SCNNode.Create();
        virtualObject.Geometry = SCNBox.Create(0.1f, 0.1f, 0.1f, 0.05f);
        sceneView.Scene.RootNode.AddChildNode(virtualObject);

        // 添加PanGesture识别器
        var panGesture = new UIPanGestureRecognizer(HandlePanGesture);
        sceneView.AddGestureRecognizer(panGesture);
    }

    private void HandlePanGesture(UIPanGestureRecognizer gesture)
    {
        var translation = gesture.TranslationInView(sceneView);

        if (gesture.State == UIGestureRecognizerState.Began || gesture.State == UIGestureRecognizerState.Changed)
        {
            // 更新虚拟对象的位置
            virtualObject.Position = new SCNVector3(
                virtualObject.Position.X + translation.X / 100,
                virtualObject.Position.Y,
                virtualObject.Position.Z + translation.Y / 100
            );
        }
    }

    // 其他ARSCNViewDelegate方法...
}
