"A powerful geometric abstraction that provide useful intermediate representations for a number of geometric operations on solid models including feature recognition, shape decomposition, finite element mesh generation, and shape design."

"A systematic and conceptually simple method is developed to generate hexahedral meshes for solid models of 3D objects. The method is rational and systematic due to a consistent, recursive utilization of skeletons to associate points on object boundaries with lower dimensional skeleton entities."
