Isogeometric segmentation: The case of contractible solids without non-convex edges
Segmentation of a 3D solid without non-convex edges into topological hexahedra. Method is based on the edge graph of the solid. Decomposition is done by means of simple combinatorial and geometric criteria. Number of resulting topological hexahedra is small.
