"so you recommend MT4j if we want our applications to run smoothly? If you find someway to make Processing applets work more fluently with CCV/touch screen could you let me know. I would much rather program in processing than trying to go through java again and learn a new framework for it."

hi josh!

your decision what framework or language you will use for your application should be rather based on your application and other things as your preferences/knowledge/time/etc. than on performance of our setup at the moment (which we will try to improve). please remember that we generally recommend the use of processing and that we can't support you with other frameworks.

i will upload some links and information from today's tutorial on my blog. the most important site for all tuio specific software is http://tuio.org/?software

Hi Josh,

a few things I've noticed while looking at your sketch:

-) typo: "iPhoneWidtth" in line 56

-) in the for-loop in the draw() function, you didn't define the photoName ( photoName = "photo" + i;)

-) you have to update the zones in your draw() function in order to make it move, e.g.:

image(photo[i], zones.getZoneX(photoName), zones.getZoneY(photoName), zones.getZoneWidth(photoName), zones.getZoneHeight(photoName));

-) In order to have relative movements, I guess you can't modify the drawing area. You have to modify the changes to the zones so they are still usable. Luckily there is new update of tuioZones (0.1.7.) which should give you the chance to set the zone data with "setZoneData(String, int, int, int, int)"

The easiest way to attach a zone to the movements of another zone is to use "attachZoneTo(String, String)"

Check out the reference for more information:

Hope that helps :)

hi josh,

are you maybe searching for the "killZone" method?

ah ok :)
try to call the attachToZone again but with empty parent zone

zones.attachZoneTo("childzone","");

nice!

hi josh,

i can't really figure out what you're asking me about the rotation. i guess you are somehow talking about the images that are originally within the phone's range, but then can get dragged out of that range to be added to the presentation queue?

hi josh,

ah ok... why don't you use the coordinates of your zones instead of the width/2 etc.?

I've just tried it with the rotation-demo from tuioZones and it worked (see below).

Also, tuioZones 0.1.8 is buggy so be careful with that!

TUIOzoneCollection zones;

void setup(){
size(screen.width,screen.height);
zones=new TUIOzoneCollection(this);
zones.setZone("zone1", width/2,height/2,300);

//added this...
zones.setZoneParameter("zone1","DRAGGABLE",true);
smooth();
font = loadFont("Serif-24.vlw");
textFont(font);
}
void draw(){
background(0);
fill (150);
zones.drawCirc("zone1");
fill (0);
float rot = zones.getGestureRotation("zone1");

//changed this...
translate(zones.getZoneX("zone1"),zones.getZoneY("zone1"));
rotate(rot*2*PI);
text("rotate me",0,0);
}
