必应地图上的3D

Are there ways to get a 3D model (maybe made by a tool like 3DVIA at) into a 3D Bing map.

I tried following the steps at http://msdn.microsoft.com/en-us/library/cc451896.aspx under the heading 3DVIA and I can't find the options mentioned.

If there is a way to import 3D models on the fly it would be great?

I'm trying to do this using the SDK at http://www.microsoft.com/maps/isdk/ajax/

The Bing Maps 3d Control has been retired so there is currently no supported 3d mode at all in Bing Maps
