Recursive Sierpinski triangle (just a bit of fun)

What fun!

A while ago I wrote a small recursion library for animated recursion.

Update screen during draw() without thread?

If you want to be able to render progressively from an unbounded recursive process in a single thread – and don’t want to use thread() – then there are ways. I mentioned a linked data structure that acts as a recursion queue. I actually have a draft library I wrote that does that – “Recursor”. Supposing you start out with a basic recursive function that cannot be animated. It looks like this: void tree(float[] seg) { line(seg[0], seg[1], seg[0]+seg[2], seg[1]+seg[3]); PVector s = new PV…

It has an animated recursive serpinski triangle demo:
