How TUIO do?

Short Version

vvvv now has native support for both sending and receiving TUIO messages!
The following nodes are available in latest alphas:

  • TUIOCursor (Network Join/Split)
  • TUIOObject (Network Join/Split)
  • TUIOBlob (Network Join/Split)
  • TUIOBundler (Network)

For receiving TUIO messages the individual split nodes can be used directly. The TUIOBundler is used for combining different types of TUIO messages in order to send them in one bundle.

Some Background

vvvv has long had support for TUIO, a protocol for receiving data from multitouch surfaces. The TUIODecoder (Network) was contributed to the addonpack by Abomb years ago.

It did what it was supposed to with only two caveats:

  • since it used an input of type String it had troubles on windows systems with non-standard string encodings
  • it was only a decoder, lacking an encoder to also be able to send TUIO messages

Enter VL: While preparing the standard library for VL it was a good exercise to create probably the worlds-first implementation of the TUIO protocol in a visual programming language. And since we can make nodes we have in VL available as nodes in vvvv it was a just a few more clicks to make the new implementation even useable for non-vl patchers. You're welcome!

There is more to the nerds pleasing: TUIO is based on the OSC protocol which meant that before being able to implement TUIO, we needed an implementation of the OSC protocol. As we've pointed out before, in VL we have the possibility to import .net libraries. So one way to support OSC in VL would have certainly been to import one of the many existing OSC libraries for .net. In fact we did that and it was good to see that it just worked. Still the real challenge of course was to also create possibly the worlds-first implementation of OSC in a visual programming language. So here we are..

Snippet of the TUIO implmentation in VL

If you're interested in the implementations have a look at the VL files in:

 \packs\VL.IO.OSC
 \packs\VL.IO.TUIO

Otherwise just go ahead, use the nodes in vvvv and please report your findings in the comments or in the alpha forum.

microdee: @synth: care to make an issue on github with console output?

synth: @microdee cant install DX11 with it, cant choose not to install it either. Cant install anything without disregarding dependensies

joreg: @okvrdz i recommend starting here: topics it should give you a good overview of what's all there

microdee: vpm is updated and DO update as it fixes an issue with new latest DX11 script https://github.com/vvvvpm/vpm/releases/latest
