    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.

I used a golf trick to plot for only 2 seconds: x.fillRect(...,...,...,t<2). If time >2 then the pixel height will be zero.

#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!
