Just tried it, it seems that the AboxSmoothFold formula got issues if the MinR value becomes 1 or higher.

Maybe division through zero or sqrt from a negative number... dunno, have not looked at the source code.

Keep it below, than it works!  Azn

Just one bonus formula for now. cheesy Use it with other two to get a customizable alternation mode. afro

I have been using FreeFileSync to see which files change on each update.
I compare the unzipped new fmlas.zip folder to my existing MB3D formula folder.
I hope this can be useful to others.

Update: I would no longer recommend FreeFileSync beyond version 6.2 due to a bug in later versions and reports of bundled unwanted software in the download from sourceforge.
FreeFileSync Portable 6.2

Hi Luca, Just a wee request; I've found your 'SphereHeightMapIFS' formula very useful
in creating apparently complex and 'techie' looking objects. I wonder how much work would be
involved in producing other heightmapped dIFS? Cube, Cylinder, Torus etc would be great,
especially if Jesse implements the extra slot/s for dIFS in DEcombinate in some future release. Yes !!
As ever, I live in hope!!  wink

It is not very complicated, though even for me much time consuming...
made a cylinder heightmap formula!

Luca seems to be long time absent, hope he is doing fine!

Greets,
j


ps: put the formula in there so it is visible for everyone:

Realy writing a formula is pretty hard and time consuming thing. Even if there are built in compiller like in UF and used formula are short, if you want your formula would be good one, you 'll have to code it and then test, and then rewrite the code and then test, and then modifie so that default settings would have stable good result and then write some hints. And here alsou one should not only to compile, but alsou to hack the code. And here are pretty many formulas. In UF there alsou are many formulas, but most of them are trash, say I realised that there arn't so many good implementations of kaliset;)
One of the most fun feature of M3D is hybridisation, and without content, you woun't have much to hybridise;)

Realy great job is done A Beer Cup

AboxPlatinium have everything. Could be that you alredy noticed (or that alredy are somewhere), but you can parameterise boxfold lenght. If lenght is some 0.1 it getts enought differen to be interesting. I found this in M Benessi version of mandelbox. Just to notice;)

if (zx > check)
{
zx=Fold - zx;
}
else if (zx < -check)
{
zx=-Fold-zx;
}

Throught anyway, this is very simple, maybe this alredy are in some of many abox formulas  hurt
