Simulations of cuts on deformable bodies have been an active research subject for more than two decades. However, previous works based on finite element methods and mass spring meshes cannot scale to complex surgical scenarios. This article presents a novel method that uses position-based dynamics (PBD) for mesh-free cutting simulation. The proposed solutions include a method to efficiently render force feedback while cutting, an efficient heat diffusion model to simulate electrocautery, and a novel adaptive skinning scheme based on oriented particles.https://extras.computer.org/extra/mcg2017030024s1.mp4.
二十多年来,对可变形物体切割的模拟一直是一个活跃的研究课题。然而,以前基于有限元方法和质量弹簧网格的工作无法扩展到复杂的手术场景。本文提出了一种使用基于位置的动力学(PBD)进行无网格切割模拟的新方法。所提出的解决方案包括一种在切割时有效呈现力反馈的方法、一种用于模拟电灼的高效热扩散模型以及一种基于定向粒子的新型自适应蒙皮方案。https://extras.computer.org/extra/mcg2017030024s1.mp4 。
