    Interesting an-anisitropic event horizon in the middle :P

    :P I couldn't fit the code to darken by depth...
  • u/danny@hille.dk
    heres another interesting rendition c.width=w=127;for(i=1e4;i--;x.fillRect(m,i/w|0,o=((w/(Y*Y+X*X)**.5+t*w&w^w*a+w-t/5*w&w))/w,.5/o))a=Math.atan2(X=-.5+(m=i%w)/w,Y=-i/-9e3)

  • Second attempt at an old school tunnel effect

    first attempt: d/23462

    Javascript garbage collector is struggling, when you create a new ImageData at each run, which results in some nasty stuttering. t||(I=new ImageData... fixes this issue
  • u/magna
    This worked for me: I=x.getImageData(0,0,c.width=w=255,h=160) (no need for t|| check)
  • u/danny@hille.dk
    u/magna while getImageData does not hit the garbage collector quite as hard, it takes about 1.3 times longer to execute, wich amounts to 53 fps, while t||(I=new ImageData... runs at a constant 60 fps (on my old 2014 macbook pro :-))
