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.

    A tumultuous and dusty planet trapped in the middle of a binary star system (my excuse for lighting both sides :D). prepend t/=6; if you have a crazy fast GPU
  • u/lionleaf
    Wow, this one is simply amazing!
  • u/aleamb
    wow! superb! amazing!
  • u/iverjo
    Very good!

    A replacement for 0|Math.random()*2 (floored) I meant to say.
  • u/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).
  • u/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.

    Sounds a bit like 2d gradient descent O_o

  • u/13thptr
    woah
  • u/username
    does not look like earth though
  • u/joeytwiddle
    It does look like a #planet though. Cool effect for 88
  • u/katkip
    That line in the middle looks a bit like Rusia
  • u/magna
    Awesome technique! You could potentially add a way to "seed" the generation with a number and then search for a seed that resembles the Earth the most using brute-force.
