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 ...
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 ...
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 ...
A Macroblock Optimization for Grid-based Nonlinear Elasticity
(The Eurographics Association, 2016)
We introduce a new numerical approach for the solution of grid-based discretizations of nonlinear elastic models. Our method targets the linearized system of equations within each iteration of the Newton method, and combines ...
Topology-Aware Neighborhoods for Point-Based Simulation and Reconstruction
(The Eurographics Association, 2016)
Particle based simulations are widely used in computer graphics. In this field, several recent results have improved the simulation itself or improved the tension of the final fluid surface. In current particle based ...
Accurate Simulation of Wound Healing and Skin Deformation
(The Eurographics Association, 2016)
We devise a method for the accurate simulation of wound healing and skin deformation. This is based on adequate formulations modeling the underlying biological processes. Cell movements and proliferation are described by ...
A Level Set Method for Ductile Fracture
(ACM SIGGRAPH / Eurographics Association, 2013)
We utilize the shape derivative of the classical Griffith's energy in a level set method for the simulation of dynamic ductile fracture. The level set is defined in the undeformed configuration of the object, and its ...
One-to-Many: Example-Based Mesh Animation Synthesis
(ACM SIGGRAPH / Eurographics Association, 2013)
We propose an example-based approach for synthesizing diverse mesh animations. Provided a short clip of deformable mesh animation, our method synthesizes a large number of different animations of arbitrary length. Combining ...
Long Range Attachments - A Method to Simulate Inextensible Clothing in Computer Games
(The Eurographics Association, 2012)
Inextensibility is one of the most fundamental properties of cloth. Existing approaches to handle inextensibility often require solving global non-linear systems and remain computationally expensive for computer game uses. ...
