A Geometry-Shader-Based Adaptive Mesh Refinement Scheme Using Semiuniform Quad/ Triangle Patches and Warping
(The Eurographics Association, 2010)In the field of garment simulation the resolution of the simulation mesh has a direct impact on visual quality. Unfortunately, an increase in mesh resolution introduces a much higher computational cost and potentially ... -
GPU Accelerated Needle Insertion Simulation using Meshfree Methods
(The Eurographics Association, 2010)Needle insertion is a common practice used in many different medical procedures. Therefore, simulation of needle insertion is of great importance for multiple purposes such as training, planning and robotic assisted ... -
Interactive Deformations with Multigrid Skeletal Constraints
(The Eurographics Association, 2010)In this paper we present an interactive method for simulating deformable objects using skeletal constraints. We introduce a two-way coupling of a finite element model and a skeleton that is attached to this model. The ... -
Interactive Simulation of a Continuum Mechanics based Torsional Thread
(The Eurographics Association, 2010)This paper introduces a continuum mechanics based thread model for use in real-time simulation. The model includes both rotary inertia, shear deformation and torsion. It is based on a three-dimensional beam model, using a ... -
A Modular Physical-Simulation Methodology
(The Eurographics Association, 2010)Physical simulation is useful so that the behaviour of objects emerges from the actions performed on them. However, a simulation simulates only one thing: the mechanics of collision behaviour for example. Further physical ... -
Normal and Friction Stabilization Techniques for Interactive Rigid Body Constraint-based Contact Force Computations
(The Eurographics Association, 2010)We present a novel, yet simple, method for stabilization of normal forces. A normal stabilization term, carefully designed from hypotheses about interactive usability, is added to the contact force problem. Further, we ... -
Optimization-based Fluid Simulation on Unstructured Meshes
(The Eurographics Association, 2010)We present a novel approach to fluid simulation, allowing us to take into account the surface energy in a precise manner. This new approach combines a novel, topology-adaptive approach to deformable interface tracking, ... -
Simulating Human Collision Avoidance Using a Velocity-Based Approach
(The Eurographics Association, 2010)We present a velocity-based model for realistic collision avoidance among virtual characters. Our approach is elaborated from existing experimental data and is based on the simple hypothesis that an individual tries to ... -
Topology-based Physical Simulation
(The Eurographics Association, 2010)This paper presents a framework to design mechanical models relying on a topological basis. Whereas naive topological models such as adjacency graphs provide low topological control, the use of efficient topological models ... -
A Triangle Bending Constraint Model for Position-Based Dynamics
(The Eurographics Association, 2010)We present a novel bending model and constraint creation method for position-based dynamics. Our new bending model is introduced as an alternative to the current state-of-the-art dihedral bending model. Our model is motivated ...
