Apologies for not having a single graphic:
Octahedral geodesic geometry. I could DM an .OBJ or tell you how to generate variations at will*. The octahedon-based geometry provides four-fold symmetry on the X, Y and Z axes. This allows variation of fineness ratio, max camber, truncations and lowering the 'equator'.
I'm also curious about the Cd curve from planar octahedron to quasi-spheroid (changing frequency).

*(
docs.blender.org/manual/en/latest/addons/add_mesh/geodesic_domes) There're capabilities there that I hadn't realized. The last picture I modeled in Wings 3d. The add-on has Square and Rotate Square parameters that would allow this to be animated.
