Answer 4

谢谢0009，你说的意思说用六个单独的GeometryModel3D描述每个面是吧？不过我总觉得应该有个更合理的实现。目前为止还没找到代码。

Answer 5

刚才搜索了一下，下面是一个老外的实现，他也是用这种方式：http://msdnbangladesh.net/blogs/razan/archive/2009/08/20/perspective-camera-animation-on-a-cube-in-wpf-3d.aspx

Answer 6

DataGrid Known Issues: Data Sources 
Certain types of data sources work best for DataGrid depending on your scenario. Following are some tips which you should keep in mind when choosing a data source for your DataGrid application:Using Linq to SQL will break sorting. In the Linq to SQL case, SQL returns Table<T> which does not implement ITypedList and therefore prevents BindingListCollectionView from correctly sorting the items. Any Linq providers that return IBindingList will see this issue. This will be fixed in an upcoming release. Until that fix is available, we recommend that you do not use a Linq to SQL (or any other provider which returns IBindingList) data source if your DataGrid requires the sorting feature. Since Linq to objects returns IEnumerable, Linq to object data sources will not break sorting.
