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/deobfuscate
    I cannot explain with words how cool this is.
  • u/donbright
    if i undersand it, the "twinkling" really adds alot. they aren't all the same size of white particle?
  • u/rodrigo.siqueira
    The "twinkling" is given by the particle size (2 last parameters of x.clearRect). Pixel size is defined by 3*S(i)+1, so it's between "3+1" and "-3+1" and the "i" makes it almost random for each pixel. An extra twinkling effect could be made by adding "t", but I thought it would be too exaggerated. You can try by changing to: K=5*S(i+t*4)
