Colorful Spheres

2008 August 07

I had my first taste of 3D in Processing dur­ing our last class, and now I’m hooked. Here’s my first attempt at gen­er­at­ing a bunch of spheres, each one a dif­fer­ent ran­dom color.

  1. Colorful spheres are cool but I am think­ing what you really want to make is a 3D chicken! Can you post your code?

  2. Sure thing -- I should have done that before. Here you go:

    //Libraries
import processing.opengl.*;

//Objects
Sphere[] spheres = new Sphere[500];

//Variables
int outerBounds = 300;



void setup() {
  size(600, 400, OPENGL);
  for (int i = 0; i < spheres.length; i++) {
    spheres[i] = new Sphere();
  }
}



void draw() {
  background(0);
  smooth();
  pushMatrix();
  translate(width/2, height/2, 0);

  //Prep lighting for drawing spheres
  noStroke();
  lights();
  ambientLight(255, 255, 255);

  //Loop through each sphere object and draw it
  for(int i = 0; i < spheres.length; i++) {
    spheres[i].display();
  }  
  popMatrix();
}



class Sphere {
  int x;
  int y;
  int z;
  int radius;

  Sphere() {
    x = int(random(-1*outerBounds, outerBounds));
    y = int(random(-1*outerBounds, outerBounds));
    z = int(random(-1*outerBounds, outerBounds));
    radius = 10;
  }

  void display() {
    pushMatrix();
    translate(x, y, z);
    int r = int(random(0,255));
    int g = int(random(0,255));
    int b = int(random(0,255));
    ambient(r, g, b);
    sphere(radius);
    popMatrix();
  }
}
