Hello Again!
Damn, i tought im asking too much...
i have another question about EVT.
here is my history... im gonna connect 3 projectores, but as i have no enought money i will no use a matrox system (or something like these), inseted im gonna use 3 computers, each one of them connected to a different projector... so im gonna have 3 projectores and 3 computers...
if you are buying any hardware, then buying a matrox triplehead2go is most likely the cheapest solution (well, putting 2 gfx-cards into a single computer might even be cheaper if you have the right sockets)
however, i guess you are not buying any hardware, and instead re-use 3 computers and 3 projectors.?
anyhow, an alternative solution for you might be to setup a chromium[1] renderfarm, which allows you to render an openGL scene to multiple computers.
so, ill use a fourth computer to manage the data in the other three computers. The manager pc will send OSC messages to each pc to turn on / off the ev_groups. Each computer will gonna project only a part of the screen.
my problem is, when im trying to send OSC messages to one of these computers, the server computer doesnt recibe anything, insetead when i use the "send" cmd locally, where all the message workg perfect...
so, in concrete, what should be the port to send the messages via OSC from the manager pc to the others computers?
the port doesn't really matter. here is a small checklist (sorry for obvious dumbnesses in there)
- are the computers networked?
- do you know the IP-addresses of each computer (or their DNS-names, if
you use a nameserver) -- can you ping each machine from each other?
- are you allowed to open the port locally? (that is: usually all ports
below 1024 are for priviliged users only; so you should use something higher, like "7777")
- is there a firewall running on either of the computers blocking
traffic in this very port ("incoming traffic" on the machine running [udpreceive]; "outgoing traffic" on the machine running [udpsend])? if so, you have to open the firewall, preferrably only on the given ports.
- do you have the IP-address in the "connect" string right? 'localhost'
and '127.0.0.1' will only ever connect to the machine you are sending on; you cannot use those addresses to reach another machine.
- do you use the same port for sending (to) and receiving.
only receive data sent from a [connect render1.mynet 7777( -> [udpsend]
how to do these things is of course depending on the operating system, which you either haven't told us, or i missed it.
