Optimising Perceived Distortion in Lossy Encoding of Dynamic Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Development of geometry data compression techniques in the past years has been limited by the lack of a metric with proven correlation with human perception of mesh distortion. Many algorithms have been proposed, but usually ...
Efficient Unsupervised Temporal Segmentation of Human Motion
(The Eurographics Association, 2014)
This work introduces an efficient method for fully automatic temporal segmentation of human motion sequences and similar time series. The method relies on a neighborhood graph to partition a given data sequence into distinct ...
Position-based Elastic Rods
(The Eurographics Association, 2014)
We present a novel method to simulate complex bending and twisting of elastic rods. Elastic rods are commonly simulated using force based methods, such as the finite element method. These methods are accurate, but do not ...
Adaptive Tetrahedral Meshes for Brittle Fracture Simulation
(The Eurographics Association, 2014)
We present a method for the adaptive simulation of brittle fracture of solid objects based on a novel reversible tetrahedral mesh refinement scheme. The refinement scheme preserves the quality of the input mesh to a large ...
Optimization Integrator for Large Time Steps
(The Eurographics Association, 2014)
Practical time steps in today's state-of-the-art simulators typically rely on Newton's method to solve large systems of nonlinear equations. In practice, this works well for small time steps but is unreliable at large time ...
Stable Orthotropic Materials
(The Eurographics Association, 2014)
Isotropic Finite Element Method (FEM) deformable object simulations are widely used in computer graphics. Several applications (wood, plants, muscles) require modeling the directional dependence of the material elastic ...
A Peridynamic Perspective on Spring-Mass Fracture
(The Eurographics Association, 2014)
The application of spring-mass systems to the animation of brittle fracture is revisited. The motivation arises from the recent popularity of peridynamics in the computational physics community. Peridynamic systems can be ...
Position and Orientation Based Cosserat Rods
(The Eurographics Association, 2016)
We present a novel method to simulate bending and torsion of elastic rods within the position-based dynamics (PBD) framework. The main challenge is that torsion effects of Cosserat rods are described in terms of material ...
Large-Scale Finite State Game Engines
(The Eurographics Association, 2016)
This paper presents a new model reduction technique that exploits large-scale, parallel precomputation to create interactive, real-time games with the visual fidelity of offline rendered films.We present an algorithm to ...
Versatile Interactions at Interfaces for SPH-Based Simulations
(The Eurographics Association, 2016)
The realistic capture of various interactions at interfaces is a challenging problem for SPH-based simulation. Previous works have mainly considered a single type of interaction, while real-world phenomena typically exhibit ...
