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.

  • Golfed fire suggestion by u/deobfuscate using a single x.fillStyle instead of separate ones for the black background and colored pixels.

  • u/Joachim
    Really nice #lighting
  • u/@noel
    Beautiful. I need to dig into this, to understand how this actually works.
  • u/rodrigo.siqueira
    Wow! Replace X^Y with X|Y to generate Sierpinski triangles. Replace Math.min with Math.max for a more dramatic effect. Remove |0 for improved golfing (a minimal visible effect on top alignment). Replace "t*1.2" with "C(i+t)*6" for the "water effect".

    Wow that's amazing!!

  • u/tomxor
    Same concept of XY displacement, but X displacement needs to be inverted when a surface is aligned along Z to give the illusion of the light comming from the observer. Completely unrealistic lighting tricks.
  • u/deobfuscate
    I don't feel like I can make any more dweets with so many good ones like this roaming around.
  • u/danny@hille.dk
    This is just out of this world. #witchcraft
  • u/vain

    Also Quake1 logo... for a while.
  • u/deobfuscate
    Looks a lot like cooler as fire: x.fillStyle=R() for(x.fillRect(0,0,w=3e3,w),x.fillStyle=R(255,100),i=2e4;i--;x.fillRect(960+S(p=t/T(i**5))/(Z=(i/T(t+i)+i*i/380)/i/i),540+C(p)/Z,K=3*S(i+t),K))x.globalAlpha=.3
  • u/deobfuscate
    (not golfed btw)
  • u/andrea270872
    Wow!
