Ellipsoid, tortellonoid & curvilinear dissections
by G.A. Sarcone & M.J. Waeber

Below are represented some peculiar dissections. Actually, unlike the regular shapes it is difficult to find curvilinear dissections. The problem is that to every convex edge of a surface there must correspond somewhere else concave edges having the same lenght and radius for it to fit into.

...tortelloni to disc



...ellipses to disc

  ...discs to tortellini
       ...lenticular shapes to disc  

  ...Paisley motif to square  

  ...disc to curvilinear shapes (flowers)
