在WPF中构建一个简单的立方体比较容易实现，可参考资料也比较众多。比较麻烦的是处理点击交互。
我在WPF中用两种方式实现了3DCube，效果图如下：
方式一： 最常见的3D内容构建模式，结构如下图。

点击交互：
给ModelUIElement3D附加事件，如下图
方式二： 使用3DTools.dll构建，结构如下图

点击交互：
给Plugin3D:InteractiveVisual3D对象的Visual对象附加点击事件，如创建一个Grid， 将Grid作为Plugin3D:InteractiveVisual3D的Visual值。
调用： this.SetCubeMaterialBrush(this.FrontPanel, "定义的ImageBrush资源的Key值", 5);
