The Skin surface

The Skin surface, defined by H. Edelsbrunner, is a smooth manifold in any dimension. In 3D case, the skin is a smooth surface formed by spherical and hyperbolic patches

The past few years, we worked on how to improve the mesh and construct the mesh dynamically:

The skin can deformed smoothly through growing

or it can morph from one shape to another. Since there are no completely smooth surfaces which model molecules, we apply the skin surface to molecular modeling.

Moreover, the tunnels, voids, or pockets can be found on the molecular surfaces:

Also, the skin surface can model ordinary objects. The next goal is how to morph between these objects efficiently:
