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.

  • u/pavel
    Also a pretty generic ray tracing 'engine.' Change f to trace other things.
  • u/pavel
    Style remix, no idea how the code I'm remixing works yet. It does not look to do ray tracing so its clearly better.
  • u/primo
    The original uses z + ∂/∂y z for saturation, which looks about right tilted at or near ~26.5°.
  • u/pavel
    for(c.width&=i=10368;i--;x.fillRect(i&127,i>>7,f(.7),1))f=n=>(z=5-i/3e3-3*n)>S(Math.hypot(i/64%2-1,i/5e3-n)*9-6*t)?f(n+.03):--z*.4 is a better one, no weird view prism.
