You find some interesting stuff when you zoom. this one is a x4096 zoom
No post prod, they really are isolated smiley

Made with Winbuddha v0.2.1,
you can find the v0.2 here : http://fractals.s3.amazonaws.com/winbuddha/winbuddha-v0.2.zip
(and the mouse control is still bugged, use arrows and + - to zoom)

what do you mean by zoom ? had no time to check it out, you mean when you limit the random starting positions to a certain area? going to give it a try now wink

well, i see it is zooming in that set needing more and more iterations to get a decent result, very nice,
i once wrote a buddha renderer for various other fractals, are you planning on incorporating different
base formulas ?! i mean buddha renderings from other diverging fractals would work in the same manner wink

nope.

The random have to be global.
The zoom is like a good old mandelbrot fractal zoom.
instead of viewing the fract from (-2,2) to (2,-2) it's can be very small range.

From what I saw of the code, this "isolated" area could be due to terminating the iteration loop prematurely (trying too aggressively to optimise). I saw some stuff to stop iterating when the point leaves certain bulbs, areas in general; for the same reasons that you can't exclude areas from the starting point, the standard results for Mandelbrot escape don't really apply here - just because the point eventually escapes under certain conditions, doesn't mean it will immediately do so (in other words, it could hop back into the viewable area a number of times before escaping).

But maybe it's a minibrot orbits? We don't know how orbits around minibrots behaves. There were renders of stoped antibuddhabrot and they didn't looked like mandelbrots.

Wow, that's deep. I did some buddhas, and I noticed that its haaaaaaaaard to zoom in. x4096 means that you must realy render a x4096 larger image and thats  fiery *#^$*( police x4096 or maybe even x4096^2  slower. There are metropolis hastings, throught.

But about variance in buddhabrot zooms: (but at the moment my image sharing site id down) :here

Hi,

Sorry to wake up this post but I think Buddhabrots are underrated and more search should be done in this area. This zoom looks awesome ! We want more : ) .
