    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.

Why can't you just be normal #sierpinski ?

u/pavel

I have no idea why this works. I was messing around with something else and then a sierpinski triangle popped out and started spinning around...
u/xem

love the explanation ^ :D
u/katkip

nice
u/pavel

I think I figured it out. If you set s=12 the structure becomes more apparent. +t*C(i) doing SO MUCH WORK is an amazing accidental find.
u/pavel

This certainly looks like a 2d projection of something 3d, how to get the depth information?
u/pavel

The trick is to rng three 2d vertices and smoothly vary them. Every combination uniquely maps to a valid 2d projection of a 3d plane so our brains infer the 3d shape.

Torus at the Discoteque

u/rodrigo.siqueira

I am inside a #torus. It reminds your previous #d3 https://www.dwitter.net/d/8707 and also this rotator https://www.dwitter.net/d/13254
u/jylikangas

I did this from scratch and managed to implement a torus in much smaller space than last time. Notice the little ghost effect trick. There's still 22 bytes left but I felt the demo was ready.
