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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Two-way Coupling of Fluids to Reduced Deformable Bodies
(The Eurographics Association, 2016)
We propose a fully monolithic two-way coupling framework that couples incompressible fluids to reduced deformable bodies. Notably, the resulting linear system matrix is both symmetric and positive-definite. Our method ...
