Abstract
In this work, our aim is to model realistic cutting and suture in real-time. For realistic rendering, the response of deformable soft tissue during the cutting and suture process should be carefully analyzed and simulated. Therefore, different behaviors of tissue resistance need to be simulated in the different phases of tool-tissue interaction. In the first phase of cutting and suture, before the tool fractures the surface we model resistance of the tissue as surface tension. Afterwards, when the tool moves into the tissue, the friction between tool and soft tissue is simulated. In addition, a hybrid elastic model consisting of a mass-spring surface with a skeleton structure is employed to speed up calculation. In our research, an abstract blood vessel is used as a case study.Keywords
