The spine within | ||||||
Previous Image | Next Image | ||||||
Description: ...been waiting for over a year to do this, Jesse beat me to it but here is my first "spine" render. I have the same strange "corroded" tip of the spine as you Jesse... will try to adjust the settings, but I also get a much more detailed end tip than Daniel had... with some unconnected (? -Probably not… ) "minibulbs"... 7200 x 5400 pixel, 10 hour render for download here: http://mandelwerk.deviantart.com/gallery/#/d3aswk8 Mandelbulb 3D Stats: Total Favorities: 0 View Who Favorited Filesize: 342.44kB Height: 900 Width: 1200 Keywords: mandelbulb inside spine Posted by: KRAFTWERK March 03, 2011, 10:06:00 AM Rating: by 3 members.

KRAFTWERK | November 18, 2011, 09:25:53 AM A day of nostalgia, remember that image very well bib... did a comment on it... Thank you! And thank you Tahyon!!! |
bib | November 17, 2011, 05:34:04 PM Nice one indeed. The inside and the spine are really strange and beautiful beasts. I did this one a long ago, but I don't remember with which program! http://www.fractalforums.com/index.php?action=gallery;sa=view;id=1329 |
Tahyon | November 17, 2011, 05:04:53 PM Impresive and technical one |
KRAFTWERK | March 04, 2011, 03:22:55 PM I did some experimenting, as Trafassel always have said, the iteration count is crucial, my minibulbs disappears and the spike gets longer with more details @ say, 500 iterations, I will render some images during the weekend. |
KRAFTWERK | March 04, 2011, 09:09:09 AM "The real iterationcount is only the ones from the first formula, the later on its are for bailing out the inside... ...A good combination of the first formulas iterationcount and the zoom factor must be found. Seems that it worked very well in your image!" I learn something everyday, thanks Jesse! I just used the same settings as you did in the image where you shared the params (http://www.fractalforums.com/index.php?action=gallery;sa=view;id=5864). @Trafassel: Here we go!!! , I will try different settings on a closer zoom of the tip this weekend... (Where is daniel? ) |
Jesse | March 04, 2011, 12:48:52 AM It seems that the artifacts only enlarges certain parts, the ones that does not decrease the vectorlength that much while iterating. But it might be possible to avoid the artifacts by resetting the vector to the start values before the inverting trick. Will try tomorrow. The result was that the artifacts were gone, but it is nearly impossible to get a good rendering. |
trafassel | March 03, 2011, 11:32:43 PM It would be cool, if the artifacts can be used to display just the "creamy" part of the inside. With "creamy" part, I mean the white material in twinbees pictures in http://www.fractalforums.com/mandelbulb-renderings/higher-iterations/msg11613/ |
Jesse | March 03, 2011, 08:57:37 PM Wow, that is awesome detailed, Great! The real iterationcount is only the ones from the first formula, the later on its are for bailing out the inside. This trick can produce artifacts because the inside is also modified by the first iterations, that is why there are some blobs in my zoomed in view. A good combination of the first formulas iterationcount and the zoom factor must be found. Seems that it worked very well in your image! |
KRAFTWERK | March 03, 2011, 02:01:15 PM Thinking about it, It might be that these "minibulbs" are "more solid parts" of something the DE misses when MB3D is doing the SphereInvC-trick? I will rerender the tip with different bailouts/DE settings... |
KRAFTWERK | March 03, 2011, 01:12:19 PM I know Trafassel! :-) I used the same settings as Jesse had in these parameters: http://www.fractalforums.com/index.php?action=gallery;sa=view;id=5864 It was set to max iterations: 70 I will for sure try to get a close up of those minibulbs! |
trafassel | March 03, 2011, 01:07:50 PM I am a great fan of the spine to :-) The minibulbs on the peak of the spine are strange. I always thought there are just repeating patterns near the peak. How much iterations you use? |
