    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.

That's really neat!
u/Polyducks

This is amazing! What's the concept behind it? How are you getting the sphere?
u/cantelope

@Polyducks, it's a golfed version of the equation of a sphere [x=sin(p1)*sin(p2);z=cos(p2);z=cos(p1)*sin(p2);] combined with a tiny 3D projector, X=cx+1/z*x*cx; Y=cy+y/z*cx, where cx/cy is center screen, and x/y/z are the 3D coordinates. Hope that makes sense! :)

*equation of a sphere: [x=sin(p1)*sin(p2);y=cos(p2);z=cos(p1)*sin(p2);]
u/alien

thanks for that, is projector a mathematical construct? does it have other names?
u/cantelope

@alien it's my own invention, the product of years of research into geometry. I wrote a tutorial with a (very ungolfed) version here https://cantelope.org/3D

Nice, do the colors represent the depth or something?
