The roads I take...

This week, I found some more time to hack around on my fun project to do a Mandelbrot set fractal renderer in XULRunner - some of that fun hackery done on the N810, some on my desktop, finally some on my laptop, and now those sources create a really usable application.
The only thing holding me back from doing a downloadable "(pre)release" package of any kind is that it's still somewhat hard to do that for XUL/JS-only XULRunner apps. I'd need to compile my own XULRunner and package it with that or such to get a usable downloadable thing.



What I added this week to bring it over the top was a zoom function that works by dragging the mouse over any piece of a rendered image and a possibility to bookmark locations and call them up again at a later point. With that, one can easily navigate to different places and get pictures like the one above - my laptop calculated and rendered the original 1280x1024 picture in a matter of seconds, with a 1.9.1 XULRunner from some time this weekend, so the same TraceMonkey present in Firefox 3.5.2 to calculate all those iterations, and I did save the contents of the canvas used to paint it as a PNG with the functionality I have in the application. Any quality degradation comes from scaling and converting to JPEG on my web server.

Oh, and there's one more interesting picture I did get out of this work:

All the fractal pixels in this image come from TraceMonkey's calculation again, of course, but the GIMP helped slightly to finish off this one.
