MATHCOMP : Buddhabrot
« on: November 29, 2006 »
my 1st entry for the challenge i suppose..

it's a program used to plot the Buddhabrot(created by Melinda Green), which is an interesting way of displaying the mandlebrot fractal.

The screenshot below is from version 0.2(too lazy to take a new shot lol :)) but i think it's safe to say that the app at its current stage is in an early alpha stage. Rendering the fractal in the screenshot took about 60 minutes(on my gf's 700 or so Mhz laptop) with the threshold set to around 2000..

Based on documentation by J.Tarbell, M.Green and P.Bourke.

I will add the sourcecode once im 100% satisfied with the program(and once the sourcecode aint sloppy spaghetti code :))

Ok, update.. the download is now what i consider 1.0a, and my final update for the competition.. also, the source is now included in the zip. i also added a new screenshot to show off my 7½h render at 20 threshold :P

so, a few thresholds to play around with that give some nice results:  20,  200,  2000,  20000..

I remember looking over the website when a link was posted here some time back. Very cool way to view the m. set. I couldn't run your program though; I got an invalid compression method when I tried to unzip the program. Not sure what was going on there.

Its SUCH a beautiful image...I'm really pleased someone entered this, well done mind.
The exe seems to crash here, or maybe Im doing something wrong.
When it appears do you just press render button?

thats strange.. any error messages? and yeah, basically you just press the render button.. or fiddle with the sliders(or press the labels to change threshold and/or update frequency);

i'll try to run it on a few different configurations and see if i can find the problem.. it's basically standard delphi so it SHOULD work on all systems..

Quite ghostly looking indeed.

I also liken this to an X-Ray photo. Very nice.

Taj, i added a new zip with some bruteforce logging.. i would appreciate if you could run it and tell me at what point it screws up and dies.. thanks in advance..

oh and btw, so far i have run it on 5 different comps, and it worked flawlessly on all om em.. so there's something weird going on here.. :(

and thanks for your kind words folks :)

Mind,

log file is *empty* after running. Program must die immediately but I notice one thing, what I see on the screen is not like your screenshot. So I enclose. Maybe its a clue, maybe not.

Also, in the end, dont worry about my machine, the fact that I cant run it does not detract from how cool the image is. Others can run it fine...must be some weirdness with my PC I guess.

hmm thats weird, seeing as you got so far as to setting the canvas up..


your logfile should ATLEAST look something like this:

Creating bitmap.
Initializing.
Setting up canvas. (this MIGHT be where you crash out, but since your logfile is empty we will never know :))

anyways, i know what you are seeing isnt what i attached in my initial post.. however, your screenshot looks screwed up in general, with the buttons and sliders beeing positioned over the canvas etc.. this is what it SHOULD look like:

This looks very nice indeed. Has a very eerie sort of x-ray kinda feel.... I Like it.
