Rotating entire space before animation

[Chrisir]

the center seems to be in the upper left corner

see tutorial

void setup() {
  size(700, 700, P3D);
  background(111);
  noStroke();
}

void draw() {
  background(111); 
  lights();

  // SPHERE at 0,0,0
  fill(255, 0, 0); // red 
  sphere(44);

  // SPHERE at center
  pushMatrix();
  translate(width/2, height/2, 0);
  fill(0, 0, 255); // blue 
  sphere(44);
  popMatrix(); 

  // SPHERE at center-122 and in the back 
  pushMatrix();
  translate(width/2, height/2-122, -333);
  fill(0, 255, 0); // green 
  sphere(44);
  popMatrix();
}

The smaller Z is, the more it is away from you (into the screen). The green sphere is farer away (Z=-333) than the other two.
