The Java/Cocoa bridge has been removed by Apple in 10.6. :-( AFAIK you can use the files from 10.5 – or switch to http://code.google.com/p/rococoa/

Hi everyone !

I'm pretty near the solution, but I cant make it work:

I've got a sketch running with toxiclib's triangleMesh.
I've got another one running with surfaceLib.

They both work fine, and i can use useVertexNormals() with surfaceLib, but I can't figure out how to connect those two.
I understand that it's possible to have a toxiclib's triangleMesh with the nice useVertexNormals from surfaceLib. But how ?!
Does anyone have an example ?

Thanks for your help

I was having the same issue with video capture being distorted in Windows 7.

Just installed winVDIG version 1.01 (not 1.05), it did the trick. You may download here: http://www.eden.net.nz/7/20071008/

ox and oy is the x and y cordinates of the object that needs to move to the goal.  gx and gy is the x and y position of the goal.  thanks for the out of bounds comment.  I'll try that.

I'm just testing minim library, I want to create cirles that are fading away eventually. I get the main circle work(which radius is 2*radius), and I don't know why the outer ring doesn't work.

P.S.: you need to change the add your own mp3 to the data folder.

  //frameRate(128);
  //mm = new MovieMaker(this, width,height,"bubbles.mov",30,MovieMaker.VIDEO, MovieMaker.LOSSLESS);
  // always start Minim first!
  minim = new Minim(this);

  // specify 1024 for the length of the sample buffers
  // the default buffer size is 1024
  song = minim.loadFile("糖不厌.mp3", 1024);
  play();

  //waveform = new WaveformRenderer();
  //song.addListener(waveform);

  // an FFT needs to know how 
  // long the audio buffers it will be analyzing are
  // and also needs to know 
  // the sample rate of the audio it is analyzing
  fft = new FFT(song.bufferSize(), song.sampleRate());

  trails = new ArrayList();

  if(play == true)  song.play();

  //  but you can use any one you like
  fft.forward(song.mix);

  //stroke(255, 0, 0, 128);

  // will look more or less like a straight line.

So last night i was scrolling through the sample for "Processing: a programming handbook for visual designers and artists" to see what it's about and the interview with Jared Tarbell really caught my eye with his "Fractal.Invaders" and i remember trying to do something like it myself some years ago but failing badly, basically my idea was to do it all with one "big" recursive function - long story short: Stack overflow.

Anyways, so i thought "hey lets try it again, i must be able to come up with some smart way of doing it" and as it turns out i was. So i thought i'd share what i came up with:

Code:

int number;
int rectWidth;
int offset;
void setup(){
  size(800,800);
  background(255);
  fill(0);
  noStroke();
  number = 1515175624; //magic constant!
  offset = 5; //ofset from the edge of the window.. sort of
  rectWidth = height/8-offset; // width of the boxes
}

void draw(){
  background(255);
  int temp = number;
  for(int y = 0; y < 8;y++){
    for(int x = 0; x < 4;x++){
      if(temp%2 == 0){
        fill(255);
      }else{
        fill(0);
      }
      rect(offset*4+(width-height)/2+x*rectWidth,offset*4+y*rectWidth,rectWidth,rectWidth);
      rect(-(width-height)/2-offset*4+width-(x+1)*rectWidth,offset*4+y*rectWidth,rectWidth,rectWidth);
      temp = temp >>1;
    } 
  }
 //number = int(random(-(MAX_INT)))+int(random((128))); //uncomment this - shit brix
}

void mousePressed(){
  number = int(random(-(MAX_INT)))+int(random((128)));
} 

I'd like to point out that while the code is indeed mine, the idea of mirroring the random-pattern to create space invader-like creature belongs to Jared (as far as i can tell). This code is just my solution to the program he described. Also i haven't actually seen Jared's source code for it was in .fla format and im still downloading flash.
There, just wanted to point that out so no one is offended or confused :)


Usage: Click to create a new random thingy.

That gives me the same error, if i try:

Code:

int numPics = 292; // change with number of points, numPics = # pictures
int numPts = 866; // number of points in spectra
PImage[] pics = new PImage[numPics];
String[][] spec;

void setup() {
  size(1000,950);
  smooth();
  for (int k = 0; k < numPics; k++) {
    for (int h = 0; h < numPts; h++) {
    String imageName =  "S5_stamp_" + nf(k, 5) + ".png";
    pics[k] = loadImage(imageName);
    String spectra = "S5_hi_spectra_" + nf(k, 5) + ".txt";
    spec[k][h] = loadStrings(spectra);  
  }
  } 

If I just try:

Code:

int numPics = 292; // change with number of points, numPics = # pictures
int numPts = 866; // number of points in spectra
PImage[] pics = new PImage[numPics];
String[][] spec;

void setup() {
  size(1000,950);
  smooth();
  for (int k = 0; k < numPics; k++) {
    for (int h = 0; h < numPts; h++) {
    String imageName =  "S5_stamp_" + nf(k, 5) + ".png";
    pics[k] = loadImage(imageName);
    String spectra = "S5_hi_spectra_" + nf(k, 5) + ".txt";
    spec = loadStrings(spectra);  
  }
  } 

I get "cannot convert from String[] to String[][]". It does actually work if I make spec just a String[] and don't specify spec[k], but that isn't what I want it to do. I want each spec[k] to be one filename so that I can then split the data from each file into the form I need for my graph.

Looks like it -- I haven't done it but check out http://java.sun.com/javase/6/docs/api/java/io/Console.html

What's different is that loadStrings() returns an array of Strings, while loadImage() only returns a single PImage. You should make spec an array of arrays of Strings - a String [][] - since that's what you're really trying to use it as.
