Hey!!

I want to connect Processing with Pure Data to launch some oscillators. Could somebody tell me which is the best way to connect both programs?.

Thank you

hi,
i uploaded a processing sketch and a pd patch to http://www.sojamo.de/files/archive/oscP5andPD.zip to get you started with communicating between processing and pd.

hi,
if you go to http://www.puredata.org/downloads and download the pd-extended version, the pd osc package is already include. on windows, there is a .reg file in the pd folder which you would have to execute once and then (re)start pd. on osx this is done automatically. then you should be set and ready to communicate between processing and pd.

hi,
first you need to open pd without double-clicking the oscPDtest.pd file, but the actual pd application. after pd has loaded properly, open (either menu or by doubleclicking) the oscPDtest.pd file and click the connect button in the patch - in the output window it should say
connected to port 127.0.0.1:12000
the issue with the i can be fixed by changing the i in the pack and unpack object to f . but it will also work if you keep the i.

hi,
i am using Pd version 0.38.4-extended-RC8 on osx and oscx works for me. you can check if osx is part of your pd release by taking a look at its package contents (ctrl + click on the pd application -> show package contents) then in folder Contents/Resources/extra there should be a folder called oscx with dumpOSC.pd_darwin, OSCroute.pd_darwin and sendOSC.pd_darwin in it.

you can also take a look at http://at.or.at/hans/pd/installers.html and http://at.or.at/hans/pd/objects.html where you can find OSC for Mac os x at the bottom of the page.

you can also check the plist in your home directory/Library/Preferences/org.puredata.pd.plist if the oscx library is included in the loadlib dictinary. mine says:
<key>loadlib16</key>
<string>oscx</string>

if it still wont work, then it might be a question for the forums at puredata.org

hope this helps,

hi,
the best thing to do would be to have 2 variables defined in your porcessing code that contain the width and height of your rect you want to control.
so when you get an osc message with address pattern /test that includes the parameters to change the dimensions of your rect, you would need to parse this message and set the variables in your code to the correspondent values of the osc message. see code below as an example.
Code:

import oscP5.*;

int myRectWidth = 10;
int myRectHeight = 10;
OscP5 oscP5;

void setup() {
/* start oscP5 and listen for incoming messages at port 12000*/
  oscP5 = new OscP5(this,12000);
}

void draw() {
  background(0);
  fill(255,0,0);
  rect(0,0,myRectWidth,myRectHeight);
}


void oscEvent(OscMessage theOscMessage) {
  if(theOscMessage.checkAddrPattern("/test")) {
    /* got a /test message */
    if(theOscMessage.checkTypetag("ii")) {
	/* the typetag of the /test message is ii. 
	so lets update the rect dimensions 
	*/
	myRectWidth = theOscMessage.get(0).intValue();
	myRectHeight = theOscMessage.get(1).intValue();
    }
  }
}
 

what should i fill in place of that?
NetAddress myRemoteLocation;

!

ok it worked with this code

/**
* oscP5sendreceive by andreas schlegel
* example shows how to send and receive osc messages.
* oscP5 website at http://www.sojamo.de/oscP5
*/

import oscP5.*;
import netP5.*;
 
OscP5 oscP5;
NetAddress myRemoteLocation;

void setup() {
 size(400,400);
 frameRate(25);
 /* start oscP5, listening for incoming messages at port 12000 */
 oscP5 = new OscP5(this,12000);
 
 /* myRemoteLocation is a NetAddress. a NetAddress takes 2 parameters,
  * an ip address and a port number. myRemoteLocation is used as parameter in
  * oscP5.send() when sending osc packets to another computer, device,
  * application. usage see below. for testing purposes the listening port
  * and the port of the remote location address are the same, hence you will
  * send messages back to this sketch.
  */
 myRemoteLocation = new NetAddress("127.0.0.1",12001);
}


void draw() {
 background(0);  
}

void mousePressed() {
 /* in the following different ways of creating osc messages are shown by example */
 OscMessage myMessage = new OscMessage("/test");
 
 myMessage.add(123); /* add an int to the osc message */

 /* send the message */
 oscP5.send(myMessage, myRemoteLocation);
}


/* incoming osc message are forwarded to the oscEvent method. */
void oscEvent(OscMessage theOscMessage) {
 /* print the address pattern and the typetag of the received OscMessage */
 print("### received an osc message.");
 print(" addrpattern: "+theOscMessage.addrPattern());
 println(" typetag: "+theOscMessage.typetag());
}
