How do semi-regular meshes address the balance between efficiency and flexibility in representing 3D geometry, and what are some common algorithms or techniques used for generating and manipulating semi-regular meshes in computer graphics?

Like how a ball can’t be made by only hexagons?

This question is actually one that is still being answered today as people come up with newer and better algorithms for manipulating 'semi-regular meshes', as you put it. I found this fantastic research paper on an algorithm that some Caltech/USC alumni developed for distance volumes. It's a great read, if you have a bit of time. They extract a mesh with a guaranteed topology and the mesh is then refined to a semi-regular mesh with a "geometrically adaptive sampling rate and good aspect ratio triangles" via surface wavefront propagation.
