Fabio Ganovelli and Carol O'Sullivan 'Animating cuts with on-the-fly re-meshing' in Eurographics 2001 short papers proceedings, Manchester, UK., 2001, pp 243 - 247.
The problem of defining a model for deformable objects which allows the user to perform cuts is still open.
Generally speaking, the reason is that such a task affects the connectivity and the topology of the mesh, while
the assumption that they never change is the basis of most algorithms for both computation of deformation and
collision detection. The drawback of approaching this problem as one of cutting based on re-meshing, is that the
mesh exhibits a higher density where it has been cut than elsewhere. This paper proposes an on-the-fly tetrahedral
simplification scheme to cope with such a fragmentation problem.
