My suggestion instead would be to use isometric bending of surfaces of
constant negative Gauss Curvature.This is possible starting with
Sine-Gordon soliton solutions suggested by Roger Bagula as above and
also Richard Palais in 3DExplorMath.
A series of animated frames that curl the surface in ond out like
warped scrolls would give a marvellous demonstration and feel of 3D
objects rather than static slices of the same. This is perhaps because
3D perception is an assembly of 2D surfaces whose connections are
grasped together for the whole object e.g.,when bent isometrically.
Richard Palais had shown me bending among all (Jacobi function)
meridians of a Sphere (the cone,sphere and ring types). I am prepared
to work further together with anyone interested.
