    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.

Trinitron #crt #scanline #fractal

u/tomxor

Finally resorted to UTF8. This is a reasonably accurate slow motion aperture grille scanline animation... Although if run very slow you will see it's not simulating 3 electron beams. t=fps (scanline) w=width (subpixels) the later must be a multiple of 3 and 5. Use X, Y and floored F to plugin your own fractal!
u/tomxor

Uncompressed: w=90,i=l=w*w/5,t=1+t*t/12; for(x.fillRect(0,0,c.width=w*2,w*2);i--;x.fillRect(X*6,Y*6,1+K,5)) X=i%w/3,Y=i/w|0,F=t-i/l,K=1-F%1,K*=(Y^X-~F)/27%1+K**8, x.fillStyle=hsl(${i*120},99%,${K*99}%)

bypassing the character limit I see using unicode escapements and regex u r very clever

Awesome!

I had a RGB CRT setup, but I hadn't been able to fit any interesting patterns: d/7512
u/tomxor

I had a look at yours magna, they are true crt, much more realistic i think. The scan lines on this are just a sideeffect I exploited and it was easy to add colour distortion in the R().
u/magna

Here we go: d/10843
u/C010011012

is it a cellular automata?
u/tomxor

Yes and no, it's a fractal n=T(0|(i/w+f^f-i/w)/(t**.7+6)) which is just a more elaborate variation of serpinsky triangles to produce more interesting patterns. Some fractals are automata, but not all automata are fractals, see here: https://en.wikipedia.org/wiki/Rule_90
u/tomxor

The implication is serpinsky triangles are computationally reducable, meaning it does not have to be computed in the same way as a cellular automata i.e state can be computed at step t directly without traversing intermidiate steps.
