Release notes here:
Is there a basic set-up guide?
Not exactly, since TUIO is provided by third party tools and devices such UPDD. So it’ll be specific to your TUIO provider.
You’ll want to make sure the TUIO provider is sending out coordinates relative to OSC/PILOT’s window. TUIO is disabled by default so you’ll need to turn it on in the Settings. Make sure your provider is sending to the port OSC/PILOT is listening on.
That’s good enough for me. Thanks, Malcolm!
