I'm trying to create a Droste effect animation of a single image inspired by M.C. Escher's print gallery version from a Leiden University study. Here is a sketch I made :
Thanks to Ultra Fractal and a Droste plugin from Jos Leys, I managed to create the desired effect :
As you can see I have a resolution problem on this last sketch due to the very high magnification (about 256 times).
I was able to create a doubly periodic image of the sketch that I could use to make my detailed drawing in a variable resolution :
My problem is that I don't find a way to convert back the image into a spiraling one. How could I do?
Thanks in advance for reading me and eventual help.
