Papervision - exact 2d dimensions

Hi.

Is there some possibility to create a 3D Plane in an exact position and dimension as a 2d MovieClip I have on the scene?

I have a movieclip with a photo, loaded from the internet on realtime. I want to create a smooth transition between the 2D scene (the MC) and the 3D scene (3D Plane), using the same photo as a texture.

How do i do that?
