Transformation between Catenoid and Helicoid

Family of minimal surfaces is an isometric deformation of catenoid into helicoid.

Note, that the normal vectors remain the same at each vertex during the transformation. Check this by enabling drawing of vertex normals by right-mouse -> control panel -> inspector -> object -> material.
