Title: Magnet Fractal Deep Zoom Post by: HPDZ on May 16, 2011, 05:04:06 AM After my embarrassing first attempt at a Magnet Fractal deep zoom animation, which turned out to have a bunch of artifactual structures due to an error in the high-precision arithmetic code in my software, I needed to make another attempt at this fractal. Quite a bit of time was put into completely revamping the code for this, including writing a whole new set of arbitrary precision proper floating-point functions and an assembly-language arbitrary precision division function. Finally, I was ready to tackle the Magnet Fractal again.
Here is the result. This is a major deep zoom to a final size of 2.64x10-74 vertically in the complex number plane, starting from a size of 3. It took my 4 GHz Core i7 980X system 156 hours to calculate the 306 massive primary data sets that were digitally interpolated to yield the 7200 frames of 1280x720 video presented here. On the MagnetDeep1 (http://www.hpdz.net/Animations/MagnetDeep1.htm) page of hpdz.net you can download silky smooth, nearly flawless, 30 Mbps encoded MP4 and WMV files. Also on that page is a 443MB ZIP file with a representative sampling of the 2950x1650 (give or take, they vary) primary data files that made this. The YouTube link here is from a 9 Mbps encoding. http://www.youtube.com/watch?v=INWREVMom24 Title: Re: Magnet Fractal Deep Zoom Post by: lycium on May 16, 2011, 05:13:22 AM Very interesting zoom, really enjoyed the music too :) Great job!
Pretty nice computer you've got, too O0 Title: Re: Magnet Fractal Deep Zoom Post by: HPDZ on May 16, 2011, 05:24:46 AM Thanks! The computer is the first thing I've really splurged on in many many years. But it is money well spent -- dedicated 100% to making these videos. |
