Simulation of organ deformation using boundary element method and meshless shape matching.
In this paper, a novel approach to perform real-time simulation of the deformation of anatomical organs is proposed for virtual surgery study. The method, which is both physics and interactivity motivated, is composed of two algorithms: boundary element method and meshless shape matching. We employ boundary element method to simulate a precise global deformation, and use meshless shape matching method to achieve low latency. In addition, a state machine is applied to control the computation patterns of deformation. The initial experiment reveals that the proposed approach can simulate organ deformations both efficiently and accurately.
