Okay, it seems that specify a min iter = 10 makes disappears most of the ghosts... smiley

In this example I use a start value = 0 (very close to zero. Choosing exactly zero makes go crazy the routines, I originally wanted to fix it but I forgot ... cry I need to force 03d^power = 03d and exp(03d) = (e,0,0) manually, with even more code waste fiery )

Exp() works better with a starting value = 0 (instead of z=#pixel start, that is MB default), instead normal power doesn't mind about this. This is a problem shared with 2D fractals. wink Try by yourself to get convinced

Julia mode is NOT affected by start, so if you have to switch you need to disable the first 2 transforms.

All the routines, that work with triplex, need to make divisions that if x=y=z=0 generate foolish exceptions sad

Hemmm thankies! :-D
I am wondering about a poly formula with terms from z8 to the constant.
It would be absolutely interesting, also adding mixed z_c terms but dunno if there are enough rooms for the vars smiley

More room for vars, and an initialization part for formulas... maybe in a year if i have the time  wink

Just got a question for the _coordvspow (maybe you have to start a new topic for this?)...
how do you combine the different formulas, just averaging the vecs brings trouble.  In this case you should also average the vector length (or the squares of it for speedup) and rescale the resulting vector to it.

cheers

I don't understand what you have said. However, afaik, this formula works fine... Azn

I was thinking that you combine the different formula options based on the percents... so is it not like the interpolation formula hybrid thingy?

Sorry, i should had looked at the sources before, but i really had no time - need all to get at least some issues from the todo list.

But i noticed that it workes now better, even i don't knoe why the formula showes up in the 3d tab when the .DEoption is 4... huh?

 rolling on floor laughing ... I am messing up everything

If you have time to look at quadraybrot, see the parent folder. I uploaded the formula in the well known archive evil grin
There are premade examples

IFS_tess is really funky, but...how would you get rid of this noise?

This problem may or may not have been absolved yet, but I took a crack at it and got rid of a lot the noise.
I hope this helps smiley


Yes it does help

thanks smiley
