Can the VTK get the world coordinates of the vertices in the read model in the OpenGL shader?

I want to use the world coordinates of the model to do the lighting calculation, and I saw in VTK opengl shader can get the model coordinates and view coordinates of vertex, I think that using model matrix multiplicate model coordinates can get the world coordinate, but I have no way to get the model matrix, do you have any good way to get the world coordinates, or model matrix?
Thanks advance for you help!

It looks like this is only in the 2D polydata mapper, but maybe the links below can help.
