Transformations

  • Order is important!
  • Let's try to rotate a square
rotate(radians(45));
translate(width/2, height/2);
rect(0, 0, 20, 20); // rectangle moves off the canvas
  • When we translate, scale or rotate we change the coordinate system
translate(width/2, height/2);
rotate(radians(45));
rect(-10, -10, 20, 20);
