[Bleeding]How to add shape with arbitrary local postion?

It seems that there isn't a postion parameter in Actor's method "addShape". But if I want to add a shape to the actor with designated local postion, what should I do?

The pose variable (it's a NxMat34) in the ShapeParams.

Thanks. I find it in the source code.

I'll think a bit more before I post my question.
