Hey all.

Just started fiddling about with processing, what an interesting visual program! For my current project I need an engine which can simulate the random 'pointilistic' dots appearing on screen but within a grid (or cell) structure, so rather then a dot appearing at any x or y point in the canvas i need it to simulate a 'pixel to pixel' affect... any ideas?

my attempts have been pretty fruitless, however heres my work so far (mainly taken from going through tutorials and experimenting with different scripts, very inexperienced so any tips would be fantastic, so far have no clue how to implement the random element of the script)

Cheers

Sam

import gifAnimation.*;

Gif loo;

int cellsize = 10;
int cols, rows;


void setup() {
  size(353,519, P3D);
  frameRate(500);
 
   
    println("gifAnimation " + Gif.version());
  loo= new Gif (this, "sam2.gif");
    loo.loop();
  
   cols = width/cellsize;
   rows = height/cellsize;
  
   
}

void draw() {
  background(0);
  loadPixels();

  for ( int i = 0; i < cols;i++) {
 
    for ( int j = 0; j < rows;j++) {
      int x = i*cellsize + cellsize/2; // x position
      int y = j*cellsize + cellsize/2; // y position
      int loc = x + y*width;           // Pixel array location
      color c = loo.pixels[loc];       // Grab the color
  
    
      pushMatrix();
      translate(x,y);
      fill(c);
      noStroke();
      rectMode(CENTER);
      rect(0,0,cellsize,cellsize);
      popMatrix();
    }
  }
}
