DOI: 10.1111/cgf.15184
Abstract: Traditional mesh‐based methods for cutting deformable bodies rely on modifying the simulation mesh by deleting, duplicating, deforming or subdividing its elements. Unfortunately, such topological changes eventually lead to instability, reduced accuracy, or computational efficiency challenges.… read more here.
