Thanks for your reply. I have another question though. You said the two processes communicated via TCP sockets. What do they actually transfer? The final rendered image? The vtk class methods calls? Or both? I also have tested the pvserver on a remote computer, and I connected to the server with 100 M network. I am wondering if the network speed is good enough for paraveiw? In other words, no huge display delay because of network? Thanks.
