Camera Motion Graphs
(The Eurographics Association, 2014)This paper presents Camera Motion Graphs, a technique to easily and efficiently generate cinematographic sequences in real-time dynamic 3D environments. A camera motion graph consists of (i) pieces of original camera ... -
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 ... -
View-Dependent Adaptive Cloth Simulation
(The Eurographics Association, 2014)This paper describes a method for view-dependent cloth simulation using dynamically adaptive mesh refinement and coarsening. Given a prescribed camera motion, the method adjusts the criteria controlling refinement to account ... -
Strain Based Dynamics
(The Eurographics Association, 2014)We propose a new set of constraints within the Position Based Dynamics (PBD) framework that allow the control of strain in directions that are independent of the edge directions of the simulation mesh. Instead of constraining ... -
Steklov-Poincaré Skinning
(The Eurographics Association, 2014)We introduce a novel and efficient simulation technique for generating physics-based skinning animations of skeleton-driven characters with full support for collision handling. Although physics-based approaches may use a ... -
Interactive Design of Modular Tensegrity Characters
(The Eurographics Association, 2014)We present a computational design tool for creating physical characters using tensegrities - networks of rigid and elastic elements that are in static equilibrium. Whereas the task of designing general tensegrities is very ... -
ChaCra: An Interactive Design System for Rapid Character Crafting
(The Eurographics Association, 2014)We propose an interactive design system for rapid crafting of planar mechanical characters. Our method combines the simplicity of sketch-based modeling with the ease of defining motion through extreme poses. In order to ... -
SteerFit: Automated Parameter Fitting for Steering Algorithms
(The Eurographics Association, 2014)In the context of crowd simulation, there is a diverse set of algorithms that model steering. The performance of steering approaches, both in terms of quality of results and computational efficiency, depends on internal ... -
Holonomic Collision Avoidance for Virtual Crowds
(The Eurographics Association, 2014)All approaches to simulating human collision avoidance for virtual crowds make simplifications to the underlying behaviour. One of the prevalent simplifications is to ignore it's holonomic aspect (i.e. sidestepping, walking ... -
Efficient Denting and Bending of Rigid Bodies
(The Eurographics Association, 2014)We present a novel method for the efficient denting and bending of rigid bodies without the need for expensive finite element simulations. Denting is achieved by deforming the triangulated surface of the target body based ... -
DenseSense: Interactive Crowd Simulation using Density-Dependent Filters
(The Eurographics Association, 2014)We present a novel algorithm to model density-dependent behaviors in crowd simulation. Our approach aims to generate pedestrian trajectories that correspond to the speed/density relationships that are typically expressed ... -
An Adaptive Virtual Node Algorithm with Robust Mesh Cutting
(The Eurographics Association, 2014)We present a novel virtual node algorithm (VNA) for changing tetrahedron mesh topology to represent arbitrary cutting triangulated surfaces. Our approach addresses a number of shortcomings in the original VNA of [MBF04]. ... -
Fast Grid-Based Nonlinear Elasticity for 2D Deformations
(The Eurographics Association, 2014)We present a deformation technique that constructs 2D warps by using spline curves to specify the starting and target shapes of selected key contours. We generate a two-dimensional deformation map from these contours by ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Ocean Waves Animation using Boundary Integral Equations and Explicit Mesh Tracking
(The Eurographics Association, 2014)We tackle deep water simulation in a scalable way, solving 3D irrotational flow using only variables stored in a mesh of the surface of the water, in time proportional to the rendered mesh. The heart of our method is a ... -
Coupling 3D Eulerian, Heightfield and Particle Methods for Interactive Simulation of Large Scale Liquid Phenomena
(The Eurographics Association, 2014)We propose a new method to simulate large scale water phenomena by combining particle, 3D grid and height field methods. In contrast to most hybrid approaches that use particles to simulate foam and spray only, we also ...
