“…Bielser, et al [7] continues along this concept and uses a state machine based on the transitions of a cutting tool across a tetrahedral's topology to perform the necessary subdivision to represent arbitrary intersections. This is extended in Seokyeol, et al [30] by using a turning point determination algorithm based on local curvature of surface meshes.…”

Artist-Driven Fracturing of Polyhedral Surface MeshesTyler Casella This paper presents a robust and artist driven method for fracturing a surface polyhedral mesh via fracture maps. A fracture map is an undirected simple graph with nodes representing positions in UV-space and fracture lines along the surface of a mesh.Fracture maps allow artists to concisely and rapidly define, edit, and apply fracture patterns onto the surface of their mesh.The method projects a fracture map onto a polyhedral surface and splits its triangles accordingly. The polyhedral mesh is then segmented based on fracture lines to produce a set of independent surfaces called fracture components, containing the visible surface of each fractured mesh fragment. Subsequently, we utilize a Voronoi-based approximation of the input polyhedral mesh's medial axis to derive a hidden surface for each fragment. The result is a new watertight polyhedral mesh representing the full fracture component.Results are aquired after a delay sufficiently brief for interactive design. As the size of the input mesh increases, the computation time has shown to grow linearly. A large mesh of 41,000 triangles requires approximately 3.4 seconds to perform a complete fracture of a complex pattern. For a wide variety of practices, the resulting fractures allows users to provide realistic feedback upon the application of extraneous forces.iv
