Back to my initial thoughts about hybridisation. I must admit, that it seems to be the same in both programs. Without adding any proofs, I tried with a simple Abox/Abox (Mbox/Mbox) hybrid. The results were pretty tha same, while the orientation of axis are very different. But still it is very hard to find some portable params (maybe Mbox / IFS works, but I need time to try) Even a simple Abox, _Abox, _addc hybrid, I used in many variations, fails, as the fractal constant factor is a global variable in Mandelbulber. I need time, that I don't have to investigate... lips are sealed

Add c does not modify C. Adds it to the current variables wink

Try using Mandelbox _ extended formula. Use AdditionConstant to add a constant (e.g same as Julia which is just an addition constant vector).

standard mandlebox is transforms :-       boxFold, sphericalFold, scale and then  an addition constant  which is            z =     z  + C ("original pixel coordinates")  * constantMultiplier,
but you can have transforms :-                boxFold, sphericalFold, scale and then  an addition constant   which is           z =     z  +  constant  (which is sometimes called "c" to confuse us.)
 
Previous versions of Mandelbulber you only had the choice of  those two options, and the fractals making up the hybrid all had to have the same addition constant. In fact the constantMuliplier  was limited to a single number ( not a vector).

Now you can have both these transforms included such that you can animate from standard MBox to Julia by infinite combinations.

As there are two instances of MBox transforms in Mandelbox_Extended tab, you can make a complete Mbox-mbox +c in that tab,  without having to slow things down by enabling hybrids.

I know, but in bulber it is "gobal" and modifys every formula. _abox, addc is the same as abox (without underline)

Only in the old formulas. In the new extended formulas  you have two instances of the z = z + additionConstant in each tab that you can choose to include in your iteration loop. If you enable hybrids you have more.  They are all individual CVector groups. wink

Correct me if I understand it in wrong way. In Mandelbulb3D there are two types of formulas. Name of some of them starts from _underline. That which has underline don't add c constant after iteration?
I can see also checkbox "repeat from here". Is this repeat hybrid sequence from pointed fractal after finishing first sequence?

Underline m3f always...
1 have no DE
2 Transform either the C constant or the vector. Some transform both. But they are useless alone. They just to that to alter subsequent formulas.

Ok? smiley

Yupp, and to complete the confusion, I forgot to write the underline before _addc. As darkbeam wrote, underline formulas are incomplete, most of them are modificators. So, correct I should have written:
_a(mazing)box, _addc is the same as a(mazing)box. Most of the time, I use first variant, even when addc is set to 1,1,1. A negcscale rotbox for example can be written in a 3 slot hybrid in m3d as _abox, _addc, _rotate (not sure about order). And the repeat from here works as you expect, after first iteration (afaik).

Just to complete the compatibility report: There once was a discussion about rotation differences here http://www.fractalforums.com/mandelbulb-software/rotboxes-mandelbulber-vs-abox-platinum/msg51114/#msg51114. Jesse also provided a little tool to transform angles between programs. I use it with success, since he wrote it!

Just played around with v2.05. Is it possible, that the mandelbox-extended has no julia mode? Tried to transport a 1.x mandelbox to extended, but allways had the mandelbrot set afterwards. Didn't find something useful within the extended options. Remaining confused...  What ?? !!

Julia coordinates = additionConstant x , y,  z

BTW.  I would not convert much into V2.05 extended formulas  as  V2.06 will be released soon. TheV2.05 extended formulas will not  be compatible with V2.06 except by editing .fract files. All parameters that currently start with the word mandebulb5, mandelbox103 and quaternion104 will be  replaced with the common word "transforms". (plus some other changes))
