在vs2017中建了個c#的wpf專案，我想將兩個.obj模型能放到同一個界面中，兩個模型都能單獨控制轉動，并且能夠疊放到一起，這個后臺怎么實作，我現在只能在一個界面里分成兩部分控制，不知道怎么放到一起
uj5u.com熱心網友回復：
只要你的坐標疊加就可以，但是需要注意元素所在是在兩個不同的空間uj5u.com熱心網友回復：
在 Model3DGroup 可以通過 model3DGroup.Children.Add(model); 的方法添加其他的 Model3DGroup 類uj5u.com熱心網友回復：
只是舉例啊。例如一個3D模型，放到Grid里面，搞2個Grid，每個里面new 一個Preview_Model，Grid位置設一塊就重疊。參考http://bbs.cskin.net/thread-16048-1-1.html

我現在是分割成了兩個界面，所以光position一樣好像不行？我是不是要把兩個放一個view里？
