• "Logistic Map" equation documentation -- this is pretty good explaining how the equation works. It gets mathematically denser as it describes the equation in more detail, but it seems a little clearer to me than tha Wikipedia page about it.

• oscP5 web page -- the web page about the oscP5 library we use to communicate data from Max/MSP to Processing.
  
  NOTE: You don't need to do the installation described on this oscP5 web page. From within the Processing app, under the main "Sketch" menu item on the top of your screen, select "Import Library -> Add Library". Scroll down in the resulting window to the "oscP5" entry. Select it, and then hit the "Install" button. Restart Processing and the oscP5 library will be available for use.
  
  
• Max/MSP tutorials -- the main page for learning the ins-and-outs of Max/MSP.
  
  
• OpenSoundControl.org -- the main site if you want to learn more about OSC and how it works. Originally this was developed at UC-Berkeley's Center for New Music and Audio Technologies (CNMAT), but now it looks like it is being hosted at Stanford.

  For handy cutting/pasting, this is the basic outline of the Processing code you will need to get values from the OSC port (being sent from Max/MSP). I'm assuming you have the oscP5 library installed (see above). Also, this is (obviously) in the "sketchOSC1" and "sketchOSC2" Processing sketches in the class archive above.

  import oscP5.*;
  
  // these two 'global' variables will hold the data we get from the OSC port
  float x;
  float y;
  
  OscP5 oscP5;
  
  void setup() {
  
    // setup code here...
  
    // we're using port # 7878
    // the Max/MSP udpsend object will need to use that port # too
    oscP5 = new OscP5(this, 7878);
  }
  
  void draw() {
  
    // drawing code here...
  
  }
  
  void oscEvent(OscMessage theOscMessage) {
    if (theOscMessage.checkAddrPattern("/xval")) {
        x = theOscMessage.get(0).floatValue();
    }
    
      if (theOscMessage.checkAddrPattern("/yval")) {
        y = theOscMessage.get(0).floatValue();
    }
  }
