Animating the Position of a 3D Camera in WPF（还有一个示例项目可以尝试！）
Rotating the Camera with the Mouse
我同意XNA可能是3D环境的最佳解决方案，但原生3D支持和硬件加速渲染也是WPF和XAML的出色特性！
正如您所看到的，XAML Viewport3D的3D摄像头与应用程序非常匹配，也使用了绑定：

<Viewport3D.Camera>
    <PerspectiveCamera x:Name="camera"
                       UpDirection="0,0,1"
                       LookDirection="{Binding RelativeSource={RelativeSource Self}, Path=Position, Converter={StaticResource lookBackConverter}}"
                       Position="0,0,0" />
</Viewport3D.Camera>

......只需执行常见的IValueConverter即可移动摄像头：

public class LookBackConverter : IValueConverter 
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return new Point3D(0,0,0) - (Point3D)value;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return null;
    }
}

下面的扩展方法实现了投影相机在任意方向上的自由飞行和旋转到欧几里得3D空间中。

using System.Windows.Input;
using System.Windows.Media.Media3D;

using static System.Windows.Input.Key;
using static System.Windows.Input.ModifierKeys;

public static class ProjectionCameraExtensions
{
    public static TCamera Move<TCamera>(this TCamera camera, Vector3D axis, double step)
        where TCamera : ProjectionCamera
    {
        camera.Position += axis * step;
        return camera;
    }

    public static TCamera Rotate<TCamera>(this TCamera camera, Vector3D axis, double angle)
        where TCamera : ProjectionCamera
    {
        Matrix3D matrix3D = new();
        matrix3D.RotateAt(new(axis, angle), camera.Position);
        camera.LookDirection *= matrix3D;
        return camera;
    }

    public static Vector3D GetYawAxis(this ProjectionCamera camera) => camera.UpDirection;
    public static Vector3D GetRollAxis(this ProjectionCamera camera) => camera.LookDirection;
    public static Vector3D GetPitchAxis(this ProjectionCamera camera) => Vector3D.CrossProduct(camera.UpDirection, camera.LookDirection);

    public static PerspectiveCamera MoveBy(this PerspectiveCamera camera, Key key) => camera.MoveBy(key, camera.FieldOfView / 180d);
    public static PerspectiveCamera RotateBy(this PerspectiveCamera camera, Key key) => camera.RotateBy(key, camera.FieldOfView / 45d);

    public static TCamera MoveBy<TCamera>(this TCamera camera, Key key, double step) where TCamera : ProjectionCamera => key switch
    {
        W => camera.Move(Keyboard.Modifiers.HasFlag(Shift) ? camera.GetYawAxis() : camera.GetRollAxis(), +step),
        S => camera.Move(Keyboard.Modifiers.HasFlag(Shift) ? camera.GetYawAxis() : camera.GetRollAxis(), -step),
        A => camera.Move(camera.GetPitchAxis(), +step),
        D => camera.Move(camera.GetPitchAxis(), -step),

        _ => camera
    };

    public static TCamera RotateBy<TCamera>(this TCamera camera, Key key, double angle) where TCamera : ProjectionCamera => key switch
    {
        Left => camera.Rotate(camera.GetYawAxis(), +angle),
        Right => camera.Rotate(camera.GetYawAxis(), -angle),
        Down => camera.Rotate(camera.GetPitchAxis(), +angle),
        Up => camera.Rotate(camera.GetPitchAxis(), -angle),

        _ => camera
    };
}

键盘和鼠标输入的处理程序

private void Window_PreviewKeyDown(object sender, KeyEventArgs e) =>
        Camera.MoveBy(e.Key).RotateBy(e.Key);

    Point from;
    private void Window_PreviewMouseMove(object sender, MouseEventArgs e)
    {
        var till = e.GetPosition(sender as IInputElement);
        double dx = till.X - from.X;
        double dy = till.Y - from.Y;
        from = till;

        var distance = dx * dx + dy * dy;
        if (distance <= 0d)
            return;

        if (e.MouseDevice.LeftButton is MouseButtonState.Pressed)
        {
            var angle = (distance / Camera.FieldOfView) % 45d;
            Camera.Rotate(new(dy, -dx, 0d), angle);
        }
    }
