“…14 The majority were purely descriptive and only 2 involved VR simulators. 31,32 Only 1 study assessed the effect of LCS training in the OR. 33 It was a randomized controlled trial in which training in LCS on cadavers was the last step of a whole training curriculum involving also a VR CBC in basic skills and cognitive courses.…”

“…If an intersection occurs, the intersection information of the current tetrahedron (triangle) will be updated and the tetrahedron (triangle) will be subdivided. We use the approach in [Steinemann et al 2006] [Pan et al 2011] for the tetrahedral and triangular subdivision. To update the PBD physical model, the processed stretch and volume-preserving constraints shall be removed.…”

This paper describes an interactive dissection approach for hybrid soft tissue models governed by position-based dynamics. Our framework makes use of a hybrid geometric model comprising both surface and volumetric meshes. The fine surface triangular mesh is used to represent the exterior structure of soft tissue models. Meanwhile, the interior structure of soft tissues is constructed by coarser tetrahedral meshes, which are also employed as physical models participating in dynamic simulation. The less details of interior structure can effectively reduce the computational cost of deformation and geometric subdivision during dissection. For physical deformation, we design and implement a position-based dynamics approach that supports topology modification and enforces the volume-preserving constraint. Experimental results have shown that, this hybrid dissection method affords real-time and robust cutting simulation without sacrificing realistic visual performance.

Abstract. Serious gaming often requires high level of realism for training and learning purposes. Haptic technology has been proved to be useful in many applications with an additional perception modality complementary to the audio and the vision. It provides novel user experience to enhance the immersion of virtual reality with a physical control-layer. This survey focuses on the haptic technology and its applications in serious gaming. Several categories of related applications are listed and discussed in details, primarily on haptics acts as cognitive aux and main component in serious games design. We categorize haptic devices into tactile, force feedback and hybrid ones to suit different haptic interfaces, followed by description of common haptic gadgets in gaming. Haptic modeling methods, in particular, available SDKs or libraries either for commercial or academic usage, are summarized. We also analyze the existing research difficulties and technology bottleneck with haptics and foresee the future research directions.
