The rendering should't be much slower than on a local PC. But what do you mean with slow. With the cluster we got up to 300 frames/s in our 10 Projector cave.If you switch on sync to v-blanc for your graphics card, you might get a maximum of 60 frames. If the graphics card ist a little bit to slow to deliver 60 Frames/s you'll get 30 Frames/s. What is your framerate with the tiefighter?
How fast is the tie-fighter if you start a viewer on one of your cave walls? > For server part, I just use the example from tutorials, but I don't know > what exactly to do between server and client, does client send the whole > scenegraphe to each server every frame? or just send whole scenegraphe > once > and then just update the transformation, or I need to do it by myself?

The Multidisplay Window is the fastest way to do rendering on multiple Servers.The ClusterWindow is the base class for all Windows that handle cluster Rendering. Derived from this class there is the Multidisplay Window and the Sort-First ClusterWindow. > > I got a laptop and a desktop at home, and build them a local network, also > the desktop connect to internet, but the server and client didn't work on > it > I remember it worked once when desktop disconneted from internet, but i > need my desktop connect to internet all day, and I don't think it should > affect the server and client, any suggestion? btw, same server and client > works well on college's cluster. > The client try to find the servers by sending a broadcast message into the network. The server answers with its name. If this name is not known on the client, the client is not able to connet the server. type hostname on both hosts and try to ping with the given name from the other host.
