In this work, a novel hybrid cutting method combining non-progressive cutting with progressive cutting is proposed, where progressive cutting is applied on the outer hull while non-progressive cutting is applied in the inner core. Therefore it keeps the visual reality while significantly increases the efficiency and stability for consequent soft-tissue simulation. In addition, we combined the nearest...
A full-fledged surgery simulator should provide functions which really train and improve surgeonspsila skill. In this work, we comprehensively illustrate our surgery simulation system from its function, architecture and methods. Next, we evaluated our system from the doctorspsila perspective. Surveys are carried out to investigate doctorspsila experience of the system. Experiments are conducted to...
In this paper, we propose full-fledged minimal invasive surgery simulator under laparoscopic environment. In addition, a novel hybrid cutting technique for volumetric tetrahedral meshed soft tissue models is presented. A progressive cutting method is applied to the model's surface elements, where the core of the model is cut non-progressively. Our work combines the advantages of both subdivision methods...
Collision response is an important component in a virtual surgery system, due to the requirements of realtime response and simulation realism. In this paper, we propose a novel hybrid collision response algorithm for generating a smooth feedback force. This algorithm takes the advantages of three traditional methods as well as gets rids of drawbacks of them. It also provides an approach to generate...
