[vtkusers] integrating data and model

[Gopalakrishnan, Gowri]

Hi all

I am using one renderer and in this renderer I render a model which i import
from a vrml file and also
some data (non vrml). Now I want to rotate my vrml model only so that it can
sit right on top of my data. 
How can  I do that.
Amy suggested that I could move the camera, but since i am using one
renderer, when I change the camera
elevation (for example)it changes the view of the data along with model. 

Can I use two renderers one for the data and one for the model and render
them both in teh same renderwindow?. How can I do that?. My first attempt at
that did not work -  it rendered the second
renderer and the first one was not visible. 
I also tried to specify two different viewport, but this has the problem
that when i am interactive with teh
data viewport the model viewport is stationary. 

But I would like them both on one....... Can anyone help me on this.  
thanks
Gowri
