my first question here. I'm totally new at graphing with Mathematica, and my general knowledge of Mathematica is not so good either.
I'm trying to replicate the drawings in Manton, Classical Skyrmions, page 5. I'd try to do that through a function of the polar angles, that assigns a color to a certain coordinate. I'm not trying to recreate any hue, I'd just be contented with a sphere with a limited number of colors.
In short, I'd like to assign colors to a sphere through a function like
where x and y are spherical angles, with y azimutal and x polar. I've read through much of the obvious documentation in understanding how to implement this idea, but so far no luck.
After drawing such spheres, I'd also like to understand how to rotate them, to draw pictures like two spheres oriented differently (where the orientation is defined through the coloring).
I'm very confused about the documentation, in particular from where to start. I'd like to have some suggestions about where to search for a guide about this type of things.
I thank you in advance.
