Fast, realistic physically based deformable models are required for real time Virtual Reality applications such as surgical simulators. The main focus of this paper is to introduce a new deformable model called NDM that is fast enough to allow interactive frame rates and plausible deformation. The NDM is integrated in an interactive Cataract Eye Surgery Simulator (CESS), which is used to model the...
As minimally invasive surgical techniques become widely available to patients, medical training systems based on virtual reality (VR) are highly desired. These systems help surgeon trainees to acquire, practice and evaluate their surgical skills. A key component in a VR-Based training system is to simulate the dynamics that occur in surgical procedures. Tissue deformation, as a most common phenomenon...
Application of Virtual Reality (VR) has attracted many researchers in computer simulation fields. In this paper, an improved mass-spring model is proposed aiming at realistic simulation of tissue deformation. Firstly, virtual springs are proposed to represent the surface. Secondly, Verlet integration is applied to calculate the position of mass points during deformation without explicit computation...
