Efficient Bounds for Point-Based Animations
(The Eurographics Association, 2007)
We introduce a new and efficient approach for collision detection in point-based animations, based on the fast computation of tight surface bounds. Our approach is able to tightly bound a high-resolution surface with a ...
Flexible Simulation of Deformable Models Using Discontinuous Galerkin FEM
(The Eurographics Association, 2008)
We propose a simulation technique for elastically deformable objects based on the discontinuous Galerkin finite element method (DG FEM). In contrast to traditional FEM, it overcomes the restrictions of conforming basis ...
Particle-Based Fluid-Fluid Interaction
(The Eurographics Association, 2005)
The interesting and complex behavior of fluids emerges mainly from interaction processes. While interactions of fluids with static or dynamic solids has caught some attention in computer graphics lately, the mutual interaction ...
Versatile Virtual Materials Using Implicit Connectivity
(The Eurographics Association, 2006)
We propose a new method for strain computation in mesh-free simulations. Without storing connectivity information, we compute strain using local rest states that are implicitly defined by the current system configuration. ...
GPU-Based Ray-Casting of Quadratic Surfaces
(The Eurographics Association, 2006)
Quadratic surfaces are frequently used primitives in geometric modeling and scientific visualization, such as rendering of tensor fields, particles, and molecular structures. While high visual quality can be achieved using ...
Visibility Transition Planning for Dynamic Camera Control
(ACM SIGGRAPH / Eurographics Association, 2009)
We present a real-time camera control system that uses a global planning algorithm to compute large, occlusion free camera paths through complex environments. The algorithm incorporates the visibility of a focus point into ...
Polyhedral Finite Elements Using Harmonic Basis Functions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Finite element simulations in computer graphics are typically based on tetrahedral or hexahedral elements, which enables simple and efficient implementations, but in turn requires complicated remeshing in case of topological ...
Example-Based 3D Scan Completion
(The Eurographics Association, 2005)
We present a novel approach for obtaining a complete and consistent 3D model representation from incomplete surface scans, using a database of 3D shapes to provide geometric priors for regions of missing data. Our method ...
A Unified Lagrangian Approach to Solid-Fluid Animation
(The Eurographics Association, 2005)
We present a framework for physics-based animation of deforming solids and fluids. By merging the equations of solid mechanics with the Navier-Stokes equations using a particle-based Lagrangian approach, we are able to ...
PriMo: Coupled Prisms for Intuitive Surface Modeling
(The Eurographics Association, 2006)
We present a new method for 3D shape modeling that achieves intuitive and robust deformations by emulating physically plausible surface behavior inspired by thin shells and plates. The surface mesh is embedded in a layer ...
