             abstract = "Computer simulation of surgical environments is always 
                         oversimplified in terms of physical behavior due to the complexity 
                         of the tissues and interactions involved, which cannot be fully 
                         simulated in real time. To better manage this trade-off between 
                         efficiency and effectiveness, we present a hybrid and adaptive 
                         environment that combines a set of methods to achieve higher 
                         accuracy and performance. Our approach merges physics-based 
                         deformation methods (Finite Elements and Mass Spring) with a 
                         non-physical method (Green Coordinates) to approximate more 
                         coarsely the behavior when the focus of the interaction is away, 
                         and more precisely during direct interaction. We experimentally 
                         demonstrate that the computational complexity of the simulation 
                         with our method does not increase with the number of objects being 
                         simulated. With our approach, a virtual surgery environment with 
                         many dynamic organs can be computed at interactive rates for the 
                         first time.",
