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. wink

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… smiley ) "minibulbs"...

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!

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.

"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: smiley Here we go!!!  afro, I will try different settings on a closer zoom of the tip this weekend... (Where is daniel? smiley )

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.

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

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!

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...

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!  afro

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?
