| Abstract | In this work we focus attention on developing a surgical simulator for performing laparoscopic Heller myotomy using force feedback. A meshless numerical technique, the method of finite spheres, is used for the purpose of physically based, real time rendering of soft tissues. A localized discretization has been employed to display the deformations in the vicinity of the tool tip as well as the interaction forces. A new technique for implementing the dispacement boundary condition is indicated. Novel cutting algorithms are implemented using point-based representation of anatomical models. Rendering of graphics models is by using a recent volumetric rendering technique known as splatting. |
