    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.

Rotating pyramid. Can anyone figure out how to make the colors smoothly darken so that it loops perfectly?

u/yonatan

with(x)for(i=3;--i;beginPath(fill(lineTo(960*i+320*(i==1)*(t%6-3),1080))))fillStyle=hsl(0 50%${i*(6+t%6)}%,moveTo(960,340),lineTo(0,1080)
u/yonatan

sorry, that's not quite right
u/f8f82804

it's great, see my remix
u/yonatan

hsl(0 50%${50+((i==1)-(t%6/6))*9}% works, but a bit long

#interactive #calligraphy #paint #brush #particles

u/tomxor

The brush pressure is derived from velocity and direction (so more caligraphic)
u/BriSeven

I love how it feels simultaneously precise and digital and messy analogue.
u/tomxor

Thanks :) The dynamics can be easily tweaked too, A*.7 and B*.7 are the inertia (could interpret as how articulated the brush is) and (C-X)/9 and (S-Y)/9 are distance based attraction to pointer (could interpret as bristle length maybe?)
u/katkip

Awesome!
