Title: Bulb Mutation Games Post by: gannjondal on March 04, 2017, 12:14:41 AM It was already a few weeks ago that I had seen some works of Sabine on her dA account in which she played with the common Mandelbulb formulas in Fragmentarium (she called it "mandelbulb-mistreatment").
That remembered me to an old bad habit of mine where I tried such mutation games for the mandelbrot set (or other formulas) in 2D. Finally I have started this old game again for the common 3D Mandelbulb in M3D (using the JIT feature). I also remembered that some time ago I tried to search for mutations here in the FF. There have been several threads that could be placed into such a category. However, I did not see a thread asking explicitely "Hey, lets play, and try to mutate the formula xyz". Of course I don't know the complete forums - so please do not hesitate to bang my had to the next wall, and to tell me that I'm too stupid to search ;-) And now I have read DarkBeam's recent thread at http://www.fractalforums.com/the-3d-mandelbulb/mixed-two-stage-bulbs/ . That was the last trigger for me to start this thread just now (as I'm not the only person who is playing this game). I know that I have not many posts in the forums yet, so that I'm probably not the perfect person to start such a thread :-) But anyway, I want to try it. -- Of course I want to present some of my results ;-) But also I want to invite you to this game. This is what I'm thinking about. Any ideas, changes... would be appreciated.
The background of the last point is: It turned out to be quite difficult to change especially the Mandelbrot set (but also the 3D Mandelbulb to a certain extend) in a useful way: The formula is so simple that every change runs the risk to destroy the picture completely. Using hybrids (especially unchanged Mandelbulbs) is one way to reduce the dose of mutations, so that something interesting may come out even for a weird change (there are other ways; however that would be another thread ;-)). Ok. Enough of jabber. At the very beginning I want to start with 3 -quite simple- examples of changes - see below replies ....

In the other half also FacY, and FacZ (this simply adds FacY*z , respective FacZ*z while calculation of the individual components) Parameter recommendation: Start to change only MutationZ. For my feeling the result is the most interesting. Still image: MutationZ = 1; everything else matches the default values of the attached .m3f (as in below pictures): (http://orig01.deviantart.net/21b7/f/2017/062/3/c/rp_m06b_001_01_v191_5_by_gannjondal-db12dex.jpg) Formula / Mutation: To show the structure of my CommonBulb formulas I want to provide a more complete listing of the formula: Code: // calculate the radius Title: Re: Bulb Mutation Games Post by: gannjondal on March 04, 2017, 12:47:37 AM Sample 2

Try this combination and see if it works; (formulas taken from http://www.fractalforums.com/index.php?topic=2062.0 ) Title: Re: Bulb Mutation Games Post by: mclarekin on March 05, 2017, 12:47:49 AM @ gannjondal I like that hybrid image above.

I have added a comment to your thread, http://www.fractalforums.com/the-3d-mandelbulb/mixed-two-stage-bulbs/ . I think the questions are related, but please correct me if needed. If I should find a result of mixing different bulbs, I will post it. @mclarekin: Thank you; you provided me a reason to try the new Mandelbulber again :) Indeed that specific hybrid caused me to continue to mutate around :yes: . I love the M3D features as well -also if it has enough weaknesses- and would wish that more people would use it. Honestly in earlier times I used the Mandelbulber more often than today (sorry :)), and was a bit sad that the development of the old OpenCL version had been stopped (although I understand the reasons). But so far I see there is still some hope... Title: Re: Bulb Mutation Games Post by: gannjondal on March 14, 2017, 12:15:36 AM Simple Mutations of Cartesian Calculations (of a power 8 bulb) Program: MB3D Notes: All previous examples have based on trigonometric calculation of (negative sine) bulbs of an arbitrary power n. In this reply I'm posting some variations of simple mutations of a cartesian calculation that was explained in this response (http://www.fractalforums.com/index.php?topic=2062.msg8680#msg8680) (I just turned sine to the more common negative sine variant by changing z -> -z). One advantage is of course that it's MUCH faster than tigonometric calculations. Another advantage is: As more terms a calculation has as easier it is to make small changes that don't destroy the whole picture. - Although you can see that you still can destroy quite much. A 'disadvantage' is: It's not that trivial to add partial rotations for components, therefore the most useful changes are quite global.
