Inner Coloring Function for periods

[josecelano]

I'm trying to find a formula to draw something like this with Gnofract 4d:

It uses a different color for each period length when a period is detected. I've seen a formula called DirectOrbitTraps but this is what I get:

By the way, I do not know if this is the right place to ask for help regarding the formula language.

I want it because I have implemented a small program to do that and I want to confirm if I'm doing it right. This is the result using my program:

Hi @josecelano - sorry I did not see this earlier. Unfortunately the method used to detect periodicity is not exposed to the coloring algorithm today so there isn't a way that I can think of to leverage the periodicity detection that Gnofract 4D does.

You could probably do your own period detection in the coloring algorithm code by looking for values of z which are very close to previous ones. Unfortunately we don't have array support at this point so it might be a bit messy.

In general I would create issues in the fract4d/gnofract4d repository, they will be seen earlier.
