END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

it was a great time but no longer maintainable by c.Kleinhuis contact him for any data retrieval,
thanks and see you perhaps in 10 years again

this forum will stay online for reference

This new improvement opens a giant field of exploring
Tomorrow i will try the inner radius fold, this formula
if r<inrad
r=2inrad-r
then r is used for inversion etc... This should fill those empty spaces inside hypermengers wink

The reason why i store all formulas also in the users local application data folderis that each copy of m3d on the computer has instantan acces of the newest formulas, regardless of where the copy is located.

I can see the logic behind that. However, this specific folder seems to contain only those formulas that have been used / loaded in M3D before ...

And m3d checkes of the newest formula version, so just downloading the new final.zip from DarkBeam and extracting it to a known folder of m3d formulas is enough to do.

Well, in my case it evidently did not work that way. The newest formula for _sphereinv, extracted from the final.zip to the M3D M3Formulas folder (timestamp: 19.06.2011) was not used by M3D, but instead the - now deleted - older version (dating from ?) seems to have been used. Could it be that when M3D copies the formula file to the application data folder, it generates a new date / timestamp for that file? At least this would explain the observed behaviour ...

Quoting myself ...

I checked it and yes, when the formula file is copied to the application data folder by Mandelbulb 3D, the current date is assigned, which results in the copied file being 'newer' than the one in the original folder ... undecided

(So, when you try to use an outdated formula file, realize that it does not work, and then download and extract the newer version, you will always encounter this problem)

Thanks cytotox for the advice, the filedate has to be kept to work properly, of course!
Will try to change it in the next verison.

Nice new additions, Luca!

A question: is there already in M3D some way of doing a "boxfold" exactly as the mandelbox does?

If not, please do a new transform for me kiss

and what does "_Folding2" do?

Had to look at this again, that are one of the first external formulas i made...
its like  z' = z+abs(z-2*fold)-abs(z-fold)-fold
so a folding affecting the positive axis (attached a graph of it, the green line. The red line was an attempt of a smooth spherical folding, but the results were disappointng).

@Lucas:
Giving formulas more options tend to cause problems, because the new values will be initialized more or less randomly!
So old parameters could not work anymore what can be really annoying if you continue an animation rendering with this formula and things screw up.
My advice would be to give the new formulas a different name!
And to overcome the huge formula count, i try to make some kind of formula hiding of unwanted ones or something...

Thank you!

Too bad if we continue to make new formulas everytime the situation can become impossible to manage, I was thinkin on the problem of liading old params, it will happen very rarely...

Many old formulas need a "revamp" as I learn new things smiley the solution can simply be, if new formulas screw up something you can simply use the old ones to finish the render, then use the new better ones , smiley
