k. Special request--- I'm trying to learn to modify this stuff, so I can do more with M3D. What do you use to assemble the code (FASM, MASM32, something else)? Could I look at your non compiled code for the above formulas (maybe even commented code) so I have a better idea of how to change the code? |

Matt there is no source really... I write it directly in assembly using OllyDbg so your formula was really coded manually. Well I had to change it using less temporary stuff and shortening it... If formulas are enough simple I do that directly. Else I use flatasm but mainly for difs shapes because layout is ready  Do you like to have a layout for formulas? ... but you need to hand code them after brutal reduction... |

Thanks Luca,
Layout would be nice. Something to look at... although if it doesn't have commentary. :eek:

Lol... For now see if the formula looks right? This is three iters of normal fold+pinetree, then one newfold+pinetree. 5+1 gives no difference  (In certain areas, the stretch is strong and a lower raystep would be needed but it is a preview right  )  To me it looks identical  - it is already downloadable As for the layout please wait!  |

Yeah you should do it! Variations include asin acos atan and atan2.
For each possible coupling of angles... x y z ... etc I have done a few now, maybe I have 6 so far that are not just reflections/rotations of others. Some look the same but then you find they are subtly different. Anyhow it is a strain on my brain, so I let myself get distracted and started testing them as hybrids in a single loop. I have found some combinations have reasonable DE  But generally the DE is a worse than a standard MBulb.  But then I have only tested a small sample. |

Why you don't let the users decide which one to pick like I did... the combinations are really too many to be explored by hand - just a thought And Johan - where is the pretty image   |

Hey Luca, as I plan to play with a solution with an integrated compiler, would you mind to provide me the original formula in order to have a (fresh) example to compare results? Best regards, Andreas |

Definitely preferable to let the user figure out what is a unique fractal or just a rotation/reflection of another fractal. I had come to the realisation that trying to figure it all out myself first was never going to happen I guess if I re-learnt my trig  i could eventually work it out.  ). Be cool to have it tabulated (which I had started to do.). I thought for a while that looking at the pwr2 versions would quickly let me work it out but found later that some combinations "appeared" to have the same pwr2 but at pwr 9 they were slightly different. An alas I am so easily distracted, like a MandelBee I "flit from fractal to fractal" LOL Cheers |

Do you just want the math, or are you looking for Luca's source? |

Hi, I mean the math, but in terms which make it easy for me to translate it into MB3D's environment (in order to avoid errors while translating it). Not sure, how it is currently done, but I was hoping there is something between the pure math and the compiled/optimized ASM-stuff. |

Andreas I totally missed your message!!! Please reply? Hi, I was hoping to have some fresh example to play with my proof-of-concept. (Still dreaming of some on-the-fly compiler where people who know the math can just enter their formulas and can play with them (like in Fragmentarium). Will never be that fast as your ASM-code, but cool to try new stuff) Best for my purpose would be the formula in pascal or C or whatever "highlevel"-language, but not ASM (My current idea is to extend the current formulas (which have pre-compiled code inside the CODE-section) by another (optional) section, maybe DELPHI-CODE, which may contain the Delphi-code of the formula and is compiled when loading the formula) |
