[edit] Continuous (smooth) coloring

Hi. Thx for new item.

  • Can you add the code to the wikibooks ?
  • As I know continues escape time uses low ierations ? Is it true in your version ?
  • Can you write more about gradients ?

Hi. There appears to be an error in the first formula for the normalized iteration count algorithm. It should be n + ( ln(ln(B)) - ln(ln(|z|)) ) / ln(P). See the original paper.

Also, the 2nd formula is not equivalent to the first for P and B == 2. The first formula is designed to match up with the colors from discrete iteration count algorithms, while the second is not. —Preceding unsigned comment added by 63.147.134.2 (talk) 20:19, 23 February 2008 (UTC)

[edit] smoothing

"Note that this new equation is simpler than the first, but it only works for Mandelbrot set's with a bailout radius of 2 and a power of 2." I dont know about Mathematics too much, but I think the bailout radius of the formula should be e, not 2.--Luzi82 (talk) 16:34, 2 February 2008 (UTC)

[edit] for programmers

There are many change in code. Evrey change is intresting and I think that should be described. Maybe in wikibooks.--Adam majewski (talk) 12:25, 17 February 2008 (UTC)

There is a wikibook about fractals, where pseudocode is encouraged! Paxinum (talk) 07:13, 18 February 2008 (UTC)
so please add coomment to this book if you are making changes (:-))--Adam majewski (talk) 09:10, 19 February 2008 (UTC)

[edit] External Link

what about linking http://sourceforge.net/projects/quickman ? it's an open source mandlebrot set generator 151.57.77.203 (talk) 22:06, 18 February 2008 (UTC)

Or this: Fractalizer Freeware Fraktal Program for Microsoft WindowsTurm (talk) 08:16, 7 April 2008 (UTC)

How about this: Mandelbrot set explorer, a Java applet for Mandelbrot set generator and explorer for educational material, and is an open source program. This applet has been accepted some textbooks and journals. --219.187.59.138 (talk) 16:15, 17 April 2008 (UTC)

I think that

The Mandelbrot and Julia sets Anatomy by Evgeny Demidov is better and also open source. --Adam majewski (talk) 07:47, 18 April 2008 (UTC)

[edit] Another External Link

I, Theta4, wanted to know if i could link to the wallpapers page on my website. As of April 30th, 2008, all of the wallpapers are from either the Mandelbrot Set or the Burning Ship Fractal. I'm going to come out and say that I'm doing this primarily because I really want some publicity on my website. I won't get very far telling kids at my school as most of the kids there don't appreciate or know what the Mandelbrot Set and family is. Also, a simple search for 'mandelbrot set wallpapers' on google isn't too helpful. There are some nice pictures that are wallpaper size, but they don't look too good as a wallpaper in my opinion. Keep in mind that I am in no way an expert on the subject of Mandelbrot Set imagery. I know my way around the set and understand both its mathematical and programmatic construction, but I can't compare to the expertise of whoever created that zoom sequence. Talk about digression!

Please read WP:NOT and WP:SPAM and WP:EL, those should answer your question.TheRingess (talk) 03:26, 1 May 2008 (UTC)
Figures. Oh well.

[edit] In Popular Culture

User 66.188.104.173 had reverted by XLinkBot a link to a video on www.youtube.com. There are art works based on the Mandelbrot set at http://www.jonathancoulton.com/songdetails/Mandelbrot%20Set# Tab: Images. Is this a link we can use? Cuddlyable3 (talk) 06:35, 20 May 2008 (UTC)

[edit] Image of a mandelbrot generalization

Hi there Cuddlyable3, I would appreciate it if you would check this out a bit before revoking the edit, although it may not look like your standard mandelbrot fractal, this is a quite standard image of a generaized mandelbrot fractal. I have placed it in the generalizations section for good reason - this is a mandelbrot with power = (-1.5,0).

A generalized 'Mandelbrot fractal' with complex power: (-1.5, 0). All points shown are on the "Inside" of the lake. The location shown is (-0.350262915827,-0.111522432559) at 820 times magnification

Please give a better reason for removing it other than 'this appears to be'. Danwills (talk) 14:55, 9 June 2008 (UTC)

This image is not notable in any way. It is not a useful illustration of anything in the article. Why was this function and this location and this magnification chosen ? What colouring algorithm has been used ? What exactly is the reader meant to learn by looking at this image ? We could fill pages with such random pretty pictures. I agree with User:Cuddlyable3 - it should be removed. Gandalf61 (talk) 15:13, 9 June 2008 (UTC)
