See the PDF book about ASCII maze here: https://10print.org/x , it is about the one liner maze which code is just; 10 PRINT CHR$(205.5+RND(1)); : GOTO 10

Cool function from u/ntsutae, but mostly tinkering with the rendering logic so its quick and short. Takes about a second.
u/pavel

Renders f on -1<=x<=1 and -9/16<=y<=9/16
u/pavel

Expects 0<=f(x,y)<=1 in that range
u/pavel

...or alternatively -1<=f(x,y)<=0 in that range too as my code is doing...
u/pavel

i can be initialized to whatever you want, it is a pure speed vs lag tradeoff
u/taupelink

wow!
u/ntsutae

👍👍
u/danny@hille.dk

NICE! - Interestingly this code f=(X,Y,n=98)=>Y*Y>n?n:f(4*X*Y-.5,Y*Y-X*X,n+1.2) from d/19821 produces an image with many similarities with this.

DANG this is speedy! - you can crank out some fractals in no time :-) f=(X,Y,n=1)=>X*X>n?n:f(4*X*Y-.5,Y*Y-X*X,n+1.2) for(i=5e4;t<1&&i--;x.fillRect(X=u&2047,u>>11,19/f(X/960-1,u/2e6-.56),1))u=-~u

u/iverjo

Great remix!
u/New_Core

u/katkip

instead of that let you can use i=4e3,j=s=0
u/pavel

The let is only there for performance to use up free chars. j and s don't need initializing. But i at 4e3 cant do 60fps without let on my machine.
u/pavel

Can just do i=2e3 if you are remixing and need chars
u/katkip

oh, i understand
u/sigveseb

awesome

Wow
