streaming live rigid body data from Motive to Max MSP

[rfall]

Has anybody managed to stream live rigid body data from motive to Max MSP using VRPN protocol? If you have, could you tell me how.

Thanks.

I think with the standard UDP object in max you might have some trouble- not to sure of the state of it these days but last time I used it it could not connect to a multicast network. There is also a lot of UDP data to parse, again, it is a difficult task with something like max- it can be done in a few lines of code (or a day and half and a million little boxes and wires in max).

There is an openframeworks addon (https://github.com/satoruhiga/ofxNatNet) that we use, it is perfect. It is possible to output simpler OSC messages for max without too much work. or even encode the data into midi if it is manageable - not too many rigid bodies.

But there don't seem to be the binaries he talks about.

You can also try to go with the UDP but I think max is too limited to join a mulitcast network and then to parse it (or at least you will have millions of boxes and wires).

This addon https://github.com/satoruhiga/ofxNatNet for openframeworks works perfectly and it is pretty easy to create something that will send you the data in more simplified ways via OSC to max.
