atanh z + 1/c = Mad hatter

tan z + 1/c = Mad Hatter's Clothes

tanh z + 1/c = Mad Hatter Cape

Fractals done in fractview for android

when I do the same formula in Xaos, it looks different

Really want to duplicate this is other programs, I would like to see if it works in mandelbulb, using it for x,y,z

My skills in programming are not as good as in the math.

What do you think?

I suspect Xaos to be buggy.  Simple escape time rendering (as Xaos) for these formulas is inappropriate (arbitrarily large values can go back near 0), so period detection is a better way. I don't know how Fractview does it.

Writing a fractal renderer is a cute way to learn programming.  You can start simple, and go as deep as you like into various aspects of coding and maths.

It looks like Fractview uses some sort of scripting system. If you post the script, I might be able to discern what kind of escape test they're applying.

As an aside, the images kind've remind me of Mother Brain. XD
