    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.

Tiny tweak, using the fact that x.l=translate,l(...),l(...) saves two characters. This is the equivalent of x[l='translate'](...),x[l](...) if you're already using with(x).

#sphere

u/donbright

thats cool... how does it work?
u/joeytwiddle

Very nice! #halftone
u/f8f82804

u/donbright: I used the parameterization from d/5600. I like it a lot because it keeps fairly even density of dots on the surface. It's based on cylindrical coordinates where each point is at a different vertical level and the points spiral around. The key is that not all values of i result in drawing a dot. We drop the back half of the sphere with C(a) >0, but we also implicitly drop points where s*i-i*i is negative
u/donbright

thanks... fascinating...

This is an experiment. if you #waitforit , look at the FPS. It will turn into a log function
