I guess the maths only related to the shape of the surface of the egg. How to parameterize them in 3D space. I didn't go through the article and I hope this makes sense, but from your text, this is what it seems.

By the way, if you are interested in improving the format of the post, feel free to contact any SteemSTEM mentor (many are available on discord). Also, it may be nice to add information on the images you are using: where they come from, of there is a copy right on them, etc...). SteemSTEM may support you but we need to be sure the images can be used freely.
