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/ciaccodavide
    oooooh, I love dithering! Nice one!
  • u/tomxor
    me too :) I didn't realise how simple the algorithm was before no, and it can be done in a single pass because it's only half a 2d kernel. Tweaking the coefficients (*R) can be fun, e.g 7*R=>5*R, 3*R=>5*R better preserves the dark and light areas in this image.

    Wow
  • u/sigveseb
    Very nice!

    the palette that's being rendered in 4 colors: for(z=i=64;i--;)for(j=z;j--;x.fillRect(16*i+448,16*j,16,16))x.fillStyle=R(i*4,j*4,255)

  • u/joeytwiddle
    Very clever mini dithers! How about dithering a sphere?
  • u/f8f82804
    A sphere is a good idea! I'm still trying to work on spatial coherence though; see my earlier Floyd-Steinberg demo to get an idea of what's possible with 2d error diffusion. This dweet is a start at using a mask instead of diffusing errors.
