And here's an animation showing how the Anti-Buddhabrot is drawn.

   Drawing the Buddhabrot  (6/26/2009 7:41 pm)

The Mandelbrot and related fractals share a feature: To calculate the color of any point in the fractal you need only calculate that single point. The Buddhabrot, however, inverts that principle. You can read more about how it's calculated here if you care to, but put shortly, for each point in the Buddhabrot you calculate, you will change the color for many other points in the fractal. This makes it hard to do the zoom-in animations for a Buddhabrot, though drawing the fractal itself is an interesting animation.

The video for this post is just that, drawing the Buddhabrot, showing the entire set as it's being drawn, and how drawing a small region of the fractal affects the rest of the fractal. One technical note: This is a mildly zoomed in view of the Buddhabrot, meaning to calculate what you see I have to calculate points outside of the view. That's why the white box representing the currently calculating area goes out of frame between each column.

As promised, here are some fractal animations. These are two simple zoom-ins of a Newton fractal and a Mandelbrot set. Enjoy.

   Fractals  (6/18/2009 9:23 pm)

Classically, when I was confronted with a new language, one of the things I'd inevitably write was a Fractal drawing program. I've written programs to draw the Mandelbrot set in languages from C++, to VB, to Excel Macros, amongst many others.

Impressively enough, I realized I've never written a fractal program in C#. I decided to correct this oversight, and you can view a gallery of fractals I've drawn here. I still have a couple of renders going, including an animation; I'll post more details when those are done.

Just put up some of the pictures I took while I was in Beijing a while ago, you can check them out here.

   Drawing with Folds  (5/31/2009 3:05 pm)

This is a new one for me. Here's an artist that "draws" on paper with nothing but folds. It's very impressive.

I think next year I'll have to see if I can find a "Draw With Fold Of The Day" calendar instead of my Origami Calendar.

   Eclipse  (5/25/2009 2:36 pm)
      Filed under: Computers, Personal


Michelle recently got a T-Mobile G1 phone. One of the compelling things for this phone, for me, is the supposed ease of development for the platform.

I come from a Windows development world, centered on Visual Studio, so I expected to be a bit of a fish out of water trying to develop for a Java platform in Eclipse. What I didn't expect, however, was the alpha nature of the tools. In just writing the standard "Hello, World" style application, I had to issue arcane command line commands, deal with dialogs that spit up error messages telling me I needed to fill them out before I opened them, and dialogs with no fewer than four progress bars going at once.

I need to find an Eclipse for Visual Studio Dummies book, and reset all of my expectations on how an IDE should work. Either that, or figure out how to develop for Android in Visual Studio.

Well, I've survived my trip to Beijing and back again. In the coming days I'll get some of the pictures I took online, but for now, I'm just trying to recover from the jetlag, so you won't see much from me for a bit.

I'm safe and sound in Beijing. I have a rather busy week ahead of me, so I'm not sure I'll get to do much in the way of touristy things, sadly

And the trip to Beijing is back on. Tell you what, it's probably just better to wait till I get back to find out when I'm going.
