Knots in Mandelbulb, and a videoMessing around with the torical coordinates (I found them http://www.fractalforums.com/theory/toroidal-coordinates/msg9428/#msg9428 here) I was able to find a distance estimation for the torus; once you find a DE you can import it in Mandelbulb3D, in Fragmentarium and in many other softwares. DE equals to an implicit surface. Links; http://en.wikipedia.org/wiki/Isosurface or http://iat.ubalt.edu/summers/math/platsol.htm (In MB there is no polygonization and the surfaces are infinitely smooth, so it's a lot better than this btw)I wondered what could happen if I take a string that runs on the surface of the torus never intersecting itself. This leads to a knot! More precisely "torus knot". I was finally able to find an explicit expression for the DE of the torus knots! That was never done before.Knighty helped me to further improve this, to get even more complicated figures.Here you go - see the topic!http://www.fractalforums.com/index.php?topic=10072Please go also to the last pages
Isolating Structures In MB3DHow to clean up your image background ~ Wow. I haven't done a journal in ages. I thought I would share a little trick for getting a nice clean background when you want to isolate a structure in Mandelbulb 3D. Why? Because sometimes the structures behind the main focus of your image or the main structure are either just small repeats of the main structure, or they are fragmented and in one way or another just not as interesting. Or the background might bury the foreground object in detail or draw attention away from what you really want the viewer to focus on. People strive for a lot of detail, and that's fine, and sometimes it works. But often I find that there's no main focus to frame your point of view. (Edit: I forgot to mention this is made using Mandelbulb 3D version 1.8.2 and I fixed a few typo's!)Sometimes you're able to focus on the foreground structure through clever use of fog, lights and depth of field settings. Nothing wrong with that either, so this is just another
