  • u/vain
    very cool. like the morphing / moving dots / lines #cube #3d
  • u/tomxor
    Very neat. The migration of the points gives it quite an etherial look.
  • u/aleamb

  • does this diagram have a name? #waitforit
  • u/farter
    finally with compressor from d/17775 , now draws incrementally non-repeating, just nicer! go fullscreen for more details.

  • u/farter
    better performance & smoother graphic but can't golf.... t?n=t+2|0:l=0;if(l<n){l=n;for(i=l;--i;)for(j=l;--j;)u=Math.PI/l,k=n-i-j,k>0&&(z=960/(1/T(u*i)+1/T(u*j)),r=48/l,x.fillRect(z-r,60+z/T(u*i)-r,r+r,r+r))}
  • u/farter
    this needs 3 secs wait. updated version at d/24464
  • u/farter
    for really nonrepeating drawing, only draw when i,j,k are coprime.
  • u/joeytwiddle
    l=60*t|0 can speed it up (but don't leave it running too long)
