在WPF中可以做出旋转的界面，这样不仅效果好看，而且节省界面和代码处理。
xaml代码如下：
<Window x:Class="V3ViewApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
Title="旋转界面" Height="360" Width="450" Background="Black" WindowState="Normal" WindowStartupLocation="CenterScreen">
<Window.Resources>
<sys:Double x:Key="grdSize">200</sys:Double>
</Window.Resources>
<Grid >
<Viewport3D ClipToBounds="True" HorizontalAlignment="Center" VerticalAlignment="Center" Height="500" Width="500">

public MainWindow()
{
InitializeComponent();
// 设置快捷键
KeyBinding forwBind = new System.Windows.Input.KeyBinding();
forwBind.Command = new ForwCommand();
forwBind.CommandParameter = ar;
forwBind.Key = System.Windows.Input.Key.Right;
this.InputBindings.Add(forwBind);
KeyBinding backBind = new System.Windows.Input.KeyBinding();
backBind.Command = new BackCommand();
backBind.CommandParameter = ar;
backBind.Key = System.Windows.Input.Key.Left;
this.InputBindings.Add(backBind);
this.Loaded += (k, k2) =>
{
};
}
}
/// <summary>
/// 向前移动
/// </summary>
public class ForwCommand : ICommand
{
public bool CanExecute(object parameter)
{
if (parameter == null)
{
return false;
}
return true;
}
public event EventHandler CanExecuteChanged;
public void Execute(object parameter)
{
AxisAngleRotation3D rot = parameter as AxisAngleRotation3D;
DoubleAnimation d = new DoubleAnimation();
d.Duration = new Duration(TimeSpan.FromMilliseconds(800));
d.By = 90d;
rot.BeginAnimation(AxisAngleRotation3D.AngleProperty, d, HandoffBehavior.Compose);
}
}
/// <summary>
/// 向后移动
/// </summary>
public class BackCommand : ICommand
{
public bool CanExecute(object parameter)
{
if (parameter == null)
{
return false;
}
return true;
}
public event EventHandler CanExecuteChanged;
public void Execute(object parameter)
{
AxisAngleRotation3D rot = parameter as AxisAngleRotation3D;
DoubleAnimation d = new DoubleAnimation();
d.By = -90d;
d.Duration = new Duration(TimeSpan.FromMilliseconds(800));
rot.BeginAnimation(AxisAngleRotation3D.AngleProperty, d, HandoffBehavior.Compose);
}
}最后用键盘左右键实现界面切换，之后可以自己改成别的快捷键进行切换。
效果如图：
