Math has its own technical language. There are tons and tons of words which mean very simple things but if you had to explain them each time again in full sentences (i.e. you'd not already have a word for that), you'd end up talking for hour where a minute would have sufficed.
Really, any specialized field has these same issues. I wish there was a way around that but I fear there isn't really any.

In fact that's probably a big part of learning new stuff: Find new ways to express it. Learning something deeply means being able to talk about it fluently.
Man! I was joking. That was beacaus I've already read the wiki article and have not understand that.
I absolutely agree.  smiley

Lol Johan wink

And I was kind of able to do powers like 4, 8 with a cheap trick. Not sure if it's ok. (And how I get z^3 still?) wink Waiting for a confirmation  grin

Thank you Tom!  A Beer Cup

First image:
Raystep multiplier 0.1
Stepwidth limiter 0.5

Second image , because it was just a test:

Raystep multiplier 0.5
Stepwidth limiter 1

I'd like to use lower values, but it get extremely slooooow….

What about a low bailout and lower iterations wink (15 to 30 should suffice)

Spiral Thingy
Nice 3D fractals.
What fractal program was used: INCENDIA or MANDELBULBER or are rendered with C++/C# ?
The exacthly formula  is just this at code on previous page?
 A peacock Wow
So if the FRACTALFORUMS annual compo would began at March, how I had believed due recent posts at "competitions and contents" chapter, I would prepare just now those 3D fractal like at this topic.

It helped, of course with a loss of detail (spirals not spiraling in as much as with high iterations) Still having issues in some cases though!

thank you  embarrass

I am not a big fan of parameter sharing because if you try to find it yourself you will for sure end up finding something even nicer.

I can tell you how I found it though, I went inside the m-set and looked around for any interesting shapes, I found a spiraly part, turned on Julia calculation, clicked on the spiral part of the image I had rendered and calculated the Julia, mostly you have to back out again before you see what you have got... Good hunting Eric!

However, if Luca is interested he might include these parameters as example parameters with the next release of M3D. wink

May, not March.  You either mistyped that or misread the post.

I for one vote for Luca including the parameter in the next release.....I could look for years and doubt if I'd find it cry
