Physically-based dynamic cell representation with consistent cell neighbor relationships

In this paper, we study a novel way to dynamically represent cellular materials' characteristics using Voronoi diagram and. Mass-Spring System (MSS). MSS is the key component which is applied on Delaunay edges. Once some selected site points are moved, MSS will drive the other connected site points and keep redistributing them until the internal forces between the Voronoi cells are balanced. The restriction imposed on cell neighbor relationships preserves the consistency of the deformable cellar material's topology.
