Many thanks to Sandor Rozsa <[email protected]>
for providing the basis for the improved TuioDemo patch.

Installation:
-------------
Copy the Quartz Composer Plugin "TuioClient.plugin" into the folder
"/Library/Graphics/Quartz Composer Plug-Ins/" and restart Quartz Composer.

Demo Patch:
-----------
This package contains a basic Quartz Composer patch "TuioDemo"
that receives and decodes TUIO messages reveived from any TUIO enabled
tracker. This patch draws a black square along with the SymbolID
for any received TuioObject as well as a grey circle for each TuioCursor.

The TuioClient Plugin has a settings field for an optional UDP port.
The default TUIO UDP port is 3333.

There are two outputs, the first one is giving all current TuioObjects,
while the second  port outputs TuioCursors. Both ports output "Structures",
which are parameter lists, containing the following fields:

s_id ... session ID
c_id ... cursor ID / symbol ID
xpos ... position on X-axis (0...1)
ypos ... position on Y-axis (0...1)
angle .. ratation angle (0...360)
xpeed, yspeed, rspeed, maccel, raccel ... speed and acceleration values

Source Code:
------------
The TuioClient Plugin comes with its full source code which can be
built using XCode 3.0 or later on Mac OS X 10.5 Leopard.
