The normal field of a shell (Jeener surface 1) [Le champ des normales d'un coquillage (surface de Jeener 1)].




Black and white display with depth-cueing of the normal field of the Jeener surface 1 with:


                          8.pi
                    Du = ------
                           200

12.pi Dv = ------- 200

Each of the normal vector is visualized using 32 spheres with decreasing radii in order to show its direction.

See a rotation of this normal field.
