does anyone have a vvvv patch that sends TUIO 2d cursor protocol through osc?

I’m working on a patch that currently tiles two cameras (will get up to four cameras like MS surface once i get more $), and does blob tracking but i want to spit out the data using TUIO.

thx,

There’s a vvvv reacTivision patch I saw a while ago that I believe sends TUIO messages through OSC. I will go look for it and post when I find it.

I found the patch, but I don’t know if it’s what you’re looking for. What’s the difference between TUIO and OSC?

You could probably combine the fiducial tracking patch from Reactivision http://vvvv.org/tiki-index.php?page=FreeFrameFiducialTracker to see how to get TUIO data, and then use this one to see how to send the OSC messages.

I also made a small vvvv patch that uses two cameras. I don’t know much about vvvv, so I doubt my patch is very efficient. If you don’t mind posting yours when its done, please do =)

from what i read TUOI is a part of OSC, someone correct me if i’m wrong

That’s what I thought, which is why I was confused. I thought TUIO was kind of a standard way of sending OSC messages. For example sending, SessionID, ID, Xpos, Ypos, Angle, etc.

Hi there,
TUIO is a protocol/format for sending messages via OSC.
So in OSC you usually use some kind of command and then some attributes e.g.
/blobs id x y

TUIO is a ptotocoll based on that OSC format so it uses the same setup with specific commands at the beginning e.g.
/tuio/2Dcur set id x y 0.0 0.0 0.0 0.0
sends the x and y coordinates of the blob number in the id variable.

basically it is just an agreement on a style of sending OSC messages
so that everyone is sending them in the same style and client apps become interchangeable.

there is a Jitter and a VVVV implementation of TUIO at Jittuio:
