Hi
I am a student and doing my project of using OpenSG on cluster, I have managed to run server and client on my cluster, but as a newbie of OpenSG there are still something I couldn't understand .
I used decorator to do projection to simulate a 4walls CAVE, and multiwindow to splite different viewports to servers, but when i run a not very big model, it seems to be very slow, even the tiefighter is rendered quite slow, I wondered if I need to do culling n frustum stuff by myself.
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?
I have used the glutwindow and multiwindow in my code, and I saw some use of passive window in examples, but what exactly passive window do, it seems for me it can do the same things as glutwindow, also I notice there is a clusterwindow, now I have realized the cluster solution by multiwindow, so I wondered what clusterwindow is for since its name is clusterwndow? :) can I do the cluster this way: generate 4 individual windows on client side, then send them to each server.
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.
thx a lot
