[away3d] away3dlite mouse coords to object3d coords

[kontakt]

Hello,

 

does anybody know how to use the built in
Flash Player 10 functions to

project mouse coords to object3d-space?

 

I´ve figured out how to do it from
object3d-space to screen in this way:

 

var _objectPoint:Vector3D = new Vector3D(100,
100, 0);

var _screenCoord:Vector3D =
Utils3D.projectVector(_object3D.viewMatrix3D,
_objectPoint);

 

But i dont know how to do itt the other way
without MouseEvent3D.

 

Thanks,

Daniel
