Anti-aliasing and Takeover

2005-04-21 (permalink tags: , )

I added anti-aliasing to Fract. For regular images, anti-aliasing is best done by averaging a grid of sub-pixels. For the Mandelbrot Set, dividing a pixel into sub-pixels actually increase the probability of falling into a punctually detailed region. A solution found by SunCode on sci.fractals is to keep only the minimal escape value of all the sub-pixels. The result is great! Unfortunately a 3x3 sub-pixels grid is 9 times slower to compute so I'm not likely to add anti-aliasing to the Web interface unless I receive some hardware donations.

In the mean time someone called Lahvak decided to take over the top 10. In the last few days he submitted several great regions. Many of them made it to the top 10. Lahvak now rules more than half of the top slots. Congratulations Lahvak!

With the trail feature, I could notice a trend. Many of the best regions originate from the tail or somewhere behind a random cardioid. Also, most of the top 10 is dominated by the funky-2 color map. This either means that this one is particularly great or that all the other maps are really ugly. I fear the later case so I'll try to make a few other maps.
