Making Things See

Welcome to the Third Dimension

Probably the first thing you learned when you started playing with Processing was how Processing orients the coordinates of your sketch. You learned that if x and y were both 0, you were at the “origin” in the top-left corner of the sketch. Next you learned that as x increased, you moved to the right until it maxed out at the width of the sketch, and likewise as y increased, you moved down until you hit the sketch’s height. Once you understood this arrangement, you could start to draw things wherever you wanted within the sketch’s window. You’ve probably used your knowledge of this orientation so much now that it’s become second nature to you. All of the work we did last chapter in learning how to iterate through ...
