Hi,
   I am trying to model an attractor set(google:"strange attractor" or "clifford attractor") in processing.  I am relatively new to the environment but I've been programming for a while and am familiar with the syntax from Wiring/Arduino.  I have run into a stumbling block when I try and render my set in 3d.  Is there some prerequisite function I am missing?

Code:

import processing.opengl.*;

  
  float ang;
  int objNo = 1024;  
  float a = -1.4;
  float b = 1.6;
  float c = 1.0;
  float d = 0.7;
  float e = -1.3;
  float f = 0.7;
  int n;
  float[]x = new float[objNo];
  float[]y = new float[objNo];
  float[]z = new float[objNo];
  float[][]xyz = {x,y,z};
  double bigX;
  double bigY;
  double bigZ;

void setup(){
  size(300, 300,OPENGL);
  xyz[0][0] = 0;
  xyz[1][0] = 0;
  xyz[2][0] = 0;
  //populate arrray//
  for (int i=0; i<xyz[0].length; i++){
    n = (i+1)%objNo;
    
    
    //xyz[0][n]//
    bigX = (Math.sin(a*xyz[1][i]))+ (c*(Math.cos(a*xyz[0][i])));
    //xyz[1][n]//
    bigY = (Math.sin(b*xyz[0][i]))+ (d*(Math.cos(b*xyz[1][i])));
    //xyz[2][n]//
    bigZ = (Math.sin(e*xyz[1][i]))+ (f*(Math.cos(f*xyz[1][i])));//
    xyz[0][n] = (float)bigX;
    xyz[1][n] = (float)bigY;
    xyz[2][n] = (float)bigZ;
  }}
  
  
  void draw(){
    background(0);
    stroke(255);
 // pointLight(51, 102, 255, 65, 60, 100); 
 // pointLight(200, 40, 60, -65, -60, -150);
  //ambientLight(70, 70, 10);
//  translate(width/2, height/2, -200 + mouseX * 0.65);
   // background(0);//
 //  rotateY(radians(ang));
 // rotateX(radians(ang));
  
 // ang++;
  
  
makePoints(xyz);}




void makePoints(float[][]pts){
float thisX;
float thisY;
float thisZ;
beginShape(POINTS);

  for (int i = 0;i<pts[0].length; i++){
     thisX=pts[0][i];
     thisY=pts[1][i];
     thisZ=pts[2][i];
    strokeWeight(1);
    
    vertex(thisX*100,thisY*100,thisZ*100-300);
  
  }
}
