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.

  • rodrigo.siqueira: I was trying to understand what is the intuitive meaning of this value "0|Math.random()*2" in the equation. I am still not sure (and I am probably wrong) but It seems that adding this "R" value to variable "a" (X position), it will displace the image to the right or left and create a similar image. It seems that it also works as a radius (zoom factor).
  • tomxor: Well my intuition from my limited understand here is that it's kind of like a fork at each point in the path that [a,b] is taking, as long as R is uniform enough the bias in the function sort of emerges and makes [a,b] follow certain paths more than others... I imagine it like a stochastic marble rolling into certain grooves in a landscape, just goto roll enough marbles to start to see the grooves.
  • tomxor: Sounds a bit like 2d gradient descent O_o

  • DataMeta: with starry backdrop: for(i=2e3;i--;)x.fillRect(i,t*99,r=4.6*Math.random(),r);if(t<121/7) x.clearRect(960+320*C(t-(h=t>88/7?1:0)),540-320*S(h+t),6,6)
  • katkip: awesome!
