| Description: fractal iteration is due to twinbee, rendering and postwork done by me. rendered with global illumination, the mandelbrot is described by a wavelength-based measured copper material. the sharp white borders etc are intended to look good on a cup

| January 19, 2009, 09:03:46 PM actually it was surprisingly simple, what i did was first iterate the function on a grid, providing inside/outside information (this can be very high res if you pack 2x2x2 bits into a grid byte). this is followed by a signed distance field (SDF) precomputation, which provides an approximate distance estimator for the intersection routine. some of the finer details are lost (obviously -- it's a fractal!), and my implementation could be better, but on the whole it was a fun experience  there is self-reflection, but it's not very evident because of the crazy surface geometry! it would be nice to revisit this fractal again with my new computer and improved methods... |

| Guest | October 18, 2008, 04:11:04 PM How did you manage to make the surrounding actually look real? |

| May 15, 2008, 12:14:43 PM yup, still down for the zoom render, exactly when depends on work (which also has a little renderfarm btw). about the rendering, that could be a loooot better still too! actually it'd be really worthwhile if i worked on that before doing the next render |

| May 13, 2008, 06:57:40 PM Oh wow, completely missed this section of the gallery until now!! I love it to bits of course - the shape is cool, but the coloring and rendering are absolutely top notch! Congrats. Still up for creating that zoom in section some time? |
| Guest | May 04, 2008, 07:30:51 PM Amazing work ! |

| May 02, 2008, 02:06:05 PM lol, i'd vote for the modified pic in the competition so the crazy otterbrot (?!) would actually get printed  |

| May 01, 2008, 07:36:30 PM @sockratease you are now officially brandmarked as fractal hippi and, ehrm, you see a very strange otter with fins  why not post it in the fractal humor section ? |

| April 30, 2008, 12:39:02 AM Looking for real-life similarities in fractals is half the fun! Trying to emulate them on purpose is the other half. And the beauty of Math and abstract art derived from it is the other half. Figuring out how there can be 3 halves is the remaining third of the fun! "however, if you're seeing otters in that weird shape, well, be sure to share around whatever you're taking!" Well... you asked for it: http://i106.photobucket.com/albums/m278/sockratease/mandelbrotter.jpg I just took a "brush tool" and outlined what I see in this thing. If you want to see these things too, watch more Bugs Bunny Cartoons! Life is so much more amusing when viewed as a cartoon. Especially a Bugs Bunny Cartoon!! |

| April 29, 2008, 06:00:26 PM lol, i've noticed a lot of people look for real-life-similarities in fractals when naming them (itself a very abstract process). however, if you're seeing otters in that weird shape, well, be sure to share around whatever you're taking!  (lol) |

| April 29, 2008, 11:00:49 AM Wow... That's an amazing render! I almost see a walrus or other sea mammal standing on it's tail, spreading it's flippers, and rearing it's head back! (so I like to seek recognizable shapes in fractals... can't be helped... call it a fetish!) (if I saw an otter - we could call it a MandelbrOtter!!) (sorry... that joke was just Awful!) |

| April 28, 2008, 01:18:59 AM it does self-reflect, potentially infinitely so (that's how the reflected underside of the mandel is lit - those are caustics) |

| April 28, 2008, 12:45:39 AM dear, thank you for this picture, and guy, the lighting surface algorithm is longer than the fractal algorith ( distance estimator value field isosurface contour of iterative function )awesome pic, if viewing in thumbnail mode, it looks so amazingly real ... what a shame, no self reflection ? |
