Collision Detection for Deformable Objects
Matthias Teschner,Stefan Kimmerle,Bruno Heidelberger,Gabriel Zachmann,Laks Raghupathi,Arnulph Fuhrmann,Marie-Paule Cani,François Faure,Nadia Magnenat-Thalmann,Wolfgang Strasser,Pascal Volino +10 more
TL;DR: In this paper, various approaches based on bounding volume hierarchies, distance fields and spatial partitioning are discussed for collision detection of deformable objects in interactive environments for surgery simulation and entertainment technology.
Journal ArticleDOI
Meshless deformations based on shape matching
TL;DR: The main idea of the deformable model is to replace energies by geometric constraints and forces by distances of current positions to goal positions, determined via a generalized shape matching of an undeformed rest state with the current deformed state of the point cloud.
Proceedings Article
Optimized Spatial Hashing for Collision Detection of Deformable Objects.
TL;DR: The presented algorithm is integrated in a physically–based environment, which can be used in game engines and surgical simulators, and employs a hash function for compressing a potentially infinite regular spatial grid.
Proceedings ArticleDOI
Weakly compressible SPH for free surface flows
Markus Becker,Matthias Teschner +1 more
TL;DR: A weakly compressible form of the Smoothed Particle Hydrodynamics method for fluid flow based on the Tait equation is presented and an improved surface tension model that is particularly appropriate for single-phase free-surface flows is discussed.
Journal ArticleDOI
Versatile rigid-fluid coupling for incompressible SPH
TL;DR: This work proposes a momentum-conserving two-way coupling method of SPH fluids and arbitrary rigid objects based on hydrodynamic forces that samples the surface of rigid bodies with boundary particles that interact with the fluid, preventing deficiency issues and both spatial and temporal discontinuities.
