    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.

3d rotation

u/taupelink

Cool!! It's also one of those figures that could be rotating either clockwise or counterclockwise.
u/cantelope

amazing!
u/tomxor

Oh wow, I always wondered about 3D fractals.
u/jellyedwards

So cool!!
u/Joachim

Wow, that's amazing! Wonder if we could get some perspective in here 🤔

Perspective #default #shadow

u/Agnes

It's a shame all of these x.reset() dweets don't work on iOS... :(
u/rodrigo.siqueira

...thanks for letting me know about this iOS limitation. So, I’ll stop using x.reset and go back to using c.width instead.
u/0x61

Should be noted reset is working fine in iOS 18.1
u/magna

Dwitter could also monkey-patch 2d context to get x.reset() working
