    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

An animation showing the impact of resolution and loop depth on the quality of a mandelbrot!

Show more comments…
u/Blacklink

I think that I 'may' have been able to make it draw the pattern without compression but to make it more unique I wanted to add these features which required compression
u/Blacklink

the resolution changes but also the max resolution increases over time, just as the loop depth increases over time
u/Xen

woah! that is damn impressive! i love it

Well that's the thing Xen it didn't feel that good haha, also Joey nice tweak I'm still a bit of a novice when it comes to all the handy tricks in getting things more compact!
