如何重用WPF 3D模型？

Question

I am trying to build an app in VS2013+C#+WPF for 3D traffic simulation. My problem is the performance. With just a 1500 very simple ugly cars the app becomes unusable.

I guess the reason is that I generate a new 3D model for each car:

Auto newAuto = new Auto();
newAuto.model = new ModelBase("car1");

where ModelBase is the function:

public ModelBase(string resourceKey)
        {
            this.Visual3DModel = Application.Current.Resources[resourceKey] as Model3DGroup; 
            this.Visual3DModel.Freeze(); //does not affect on performance for some reason 
        }

and car1.xaml is a car model converted from 3DS using zam3d software. After converting I tried hard to minimize the number of triangles in it. That's why the cars are ugly :)

The question is: how to load the 3D model into graphics memory once and then reuse it? Or am I doing something wrong?

please, help! I have spent soooo much time on it!!!

WPF不适合复杂的场景，您需要切换到OpenGL或DirectX 。
