Sphere eversion
WebMay 11, 2024 · Now the sphere of A undergoes eversion, the surface bends and twists and so do the surface normals of A and therefore the vectors in B. When eversion is done, the sphere has been turned inside-out and so the surface normals in A are pointing inward and therefore the vectors in B point inward.

WebThe Sphere Eversion In 1948, Stephen Smale, a mathematician who was then at the University of Chicago, proved that it was possible to turn the surface of a sphere inside out by a special kind of deformation called a “regular homoto- py”.

WebAbstract The mathematical process of everting a sphere (turning it inside-out allowing self-intersections) is a grand challenge for visualization because of the complicated, ever-changing internal structure. We have computed an optimal minimax eversion, requiring the least bending energy.
