I have been searching this for quite sometime but could not find an appropriate method. How to import 3D models in a WPF application at runtime when user selects a model. It can be built in any one of the popular 3D modelling software, 3DS max, Maya, Blender etc, not all. Any one of the formats .3DS, .MAX, .FBX, .obj etc is required to be imported.

如果有可用于这个免费图书馆，请注明他们，如果我必须写在code自己，请指导如何以及在哪里开始。

If there are free libraries available for this, please mention them, and if i have to write the code myself, please guide how and where to start.
