Parallel deformation of heterogeneous ChainMail models: application to interactive deformation of large medical volumes

In this work we present a new solution for correctly handling heterogeneous materials in ChainMail models, which are widely used in medical applications. Our core method relies on two main components: (1) a novel timestamp-based propagation scheme that tracks the propagation speed of a deformation through the model and allows to correct ambiguous configurations, and (2) a novel relaxation stage that performs an energy minimization process taking into account the heterogeneity of the model. In addition, our approach extends the SP-ChainMail algorithm by supporting interactive topology changes and handling multiple concurrent deformations, increasing its range of applicability.
