    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.

64x36 20FPS Random Sampling Renderer

u/LimeLaser

My attempt to implement per-pixel rendering at interactive rates. Using a Linear Congruential Generator, the pixels to render are chosen psuedo-randomly. It takes 3 frames to render all 2304 pixels, so the actual FPS is 20.

I don't even ... this is so cool, like a forest
u/pavel

This thing ((i&2)-1)*(2+i%7) takes so many characters. If somebody can figure out a shorter way to generate random-ish positive and negative numbers that aren't too close to zero that would be awesome. 7*C(i) is almost perfect but gets close to zero so you'd have trees on the path.
u/pavel

Oh! 3/C(i) works well here, but has no bound which will be an issue in other contexts.

I originally felt a little ashamed to post because the distribution of dots is not uniform, hence "dirty", but your kind comments have reminded me that nobody really cares. Indeed, bugs like this can even give an image more character than perfection would. Thanks! 🙏

rainbow spinning bars, first dweet bear with me!

u/Xen

onlyneed to set width, extra tasty byte ;-)
u/sybarita

thanks ya i realized that after i did these ones super big accidentally, since i had already set it super wide the bottom half of the canvas was empty so i just changed the height val instead of scaling all the other values cause im lazy. used your guide to get started playing with these btw, thanks for that!
u/Xen

omg really? glad it helped :-)
