Multiple instances of a PShape in a GROUP

I understand from reading the JavaDocs, that Translate is not allowed within a createShape. I tried it anyways in the code below and it does not work, so my question is, what do I use to translate the multiple children that I want to add to the GROUP. I have also done some troubleshooting and it appears that no matter how many addChild() I use, it only adds a single instance of the "cube" that I created. My goal is to make 6 of the cubes in different colors and add one of the 6 cubes based on criteria, but one step at a time, first, how do I make a 20X20X20 3D matrix of these cubes. I can do it by drawing all of the cubes, but I am trying to make this completely object oriented.

I have tried commenting out the PeasyCam in order to make sure it not causing any issues. If I comment out the cam= statement, the program still only draws out ONE cube, but it will be in the top left corner instead of the center due to PeasyCam coordinates.

Any and all suggestions are welcomed.

import processing.opengl.*;
import peasy.*;
PeasyCam cam;
PShape cube, world, world2;
float CS = .25;
int CPS = 20;
float offset = 0;


void setup()  {
  size(640, 640, P3D);
  cam = new PeasyCam(this, CPS*10);  //If commented out, cube moves to top left corner
  noStroke();

  cube = createShape();
  cube.beginShape(QUADS);
  cube.fill(0x44FF0000); cube.vertex(-CS,  CS,  CS);cube.vertex( CS,  CS,  CS);cube.vertex( CS, -CS,  CS);cube.vertex(-CS, -CS,  CS);
  cube.fill(0x4400FF00); cube.vertex( CS,  CS,  CS);cube.vertex( CS,  CS, -CS);cube.vertex( CS, -CS, -CS);cube.vertex( CS, -CS,  CS);
  cube.fill(0x440000FF); cube.vertex( CS,  CS, -CS);cube.vertex(-CS,  CS, -CS);cube.vertex(-CS, -CS, -CS);cube.vertex( CS, -CS, -CS);
  cube.fill(0x44FFFF00); cube.vertex(-CS,  CS, -CS);cube.vertex(-CS,  CS,  CS);cube.vertex(-CS, -CS,  CS);cube.vertex(-CS, -CS, -CS);
  cube.fill(0x4400FFFF); cube.vertex(-CS,  CS, -CS);cube.vertex( CS,  CS, -CS);cube.vertex( CS,  CS,  CS);cube.vertex(-CS,  CS,  CS);
  cube.fill(0x44FF00FF); cube.vertex(-CS, -CS, -CS);cube.vertex( CS, -CS, -CS);cube.vertex( CS, -CS,  CS);cube.vertex(-CS, -CS,  CS);
  cube.endShape(CLOSE);

  world=createShape(GROUP);
  world.addChild(cube);// This is the cube in the center or top left corner.
  for (int i = 0; i < CPS; i++) {
      for (int j = 0; j < CPS; j++) {
          for (int k = 0; k < CPS; k++) {
          cube.translate(i,j,k);               //This is not allowed and does not work.
          world.addChild(cube);           //This only adds the cube once.
          }}}
 }

void draw()  {
  background(127);
  scale(90);
  shape(world,0,0);
