这个小程序使用Wpf模拟QQ快速换装页面的动画特效，通过使用组合快捷键Ctrl+Left或Ctrl+Right，可实现Image平滑的向左或者向右 滑动，页面如下，有兴趣的朋友可以下载源码：http://files.cnblogs.com/5460600/Switch.rar
在构建这个示例的3D场景时，使用了ModelVisual3D和Model3DGroup元素，ModelVisual3D是一个3D容器类，用来包含 3D元素，在这里 使用Model3DGroup打包了3个GeometryModel3D，每个GeometryModel3D的Materia各填充了一幅Image，将Model3DGroup设置为 ModelVisual3D的Content，使用RotateTransform3D和TranslateTransform3D对Model3DGroup集合中的每个GeometryModel3D应用模型变换 ，最终出现图示的效果
