3d Cellular Automata

[TwoPeas]

Hi. I am very new to processing, and currently I am doing some exploration on 3D Cellular Automata. Basically, I followed the tutorial of Cellular Automata by Jose Sanchez ( in 2d) and I am trying to edit the codes into 3d. The first intention is to make the cell grows in the z-axis. I tried a few times, and I did not manage to do it. So in the end I chose to make the whole thing as a box, and have the activity of cells inside the box. But I failed. Could anyone help me please?

if there's a way to iterate everything in the z-axis, it would be the best! ( as that was the first intention )

Below is the code:

Code: Select all

import peasy.*;
import toxi.geom.*;
PeasyCam cam; 

int cols = 50; // population
int rows = 50;
int depth = 50;


CA [][][] grid = new CA [cols][rows][depth]; //declare two dimmensional array

void setup () {
  size(1280, 720, P3D);
  frameRate (12);

  cam = new PeasyCam (this, 100);

  for (int i = 0; i < cols; i++) {
    for (int j = 0; j < rows; j++) {
      for ( int k = 0; k < depth; k++) {

        Vec3D ptLoc = new Vec3D ( i* 10, j * 10, k*10 );
        grid [i][j][k] = new CA (ptLoc, i, j, k);
      }
    }
  }
}

void draw () {
  background (0);
  stroke (255);
  fill (255, 60);
  // rect (0,0,600,600);

  for (int i = 0; i < cols; i++) {
    for (int j = 0; j < rows; j++) {
      for ( int k = 0; k < depth; k++) {

        grid[i][j][k].run();
      }
    }
  }


  for (int i = 0; i < cols; i++) {
    for (int j = 0; j < rows; j++) {
      for ( int k = 0; k < depth; k++) {
        grid[i][j][k].updateType();
        grid[i][j][k].loc.z = grid[i][j][k].loc.z  ;
      }
    }
  }
}

    //if i have too many neighbours around me, i die out of the over population
    if (type == 1 && count < 2) {

    }

    if (type == 1 && count <=3 && count >=2) {

    if (type ==1 && count > 3) {

    }

    if (type == 0 && count == 3) {

  void display () {

    if (type == 1) {

Thank you.
