Fast Simulation of Deformable Characters with Articulated Skeletons in Projective Dynamics
(ACM, 2019)
We propose a fast and robust solver to simulate continuum-based deformable models with constraints, in particular, rigid-body and joint constraints useful for soft articulated characters. Our method embeds degrees of freedom ...
Real-Time Dynamic Wrinkling of Coarse Animated Cloth
(ACM Siggraph, 2015)
Dynamic folds and wrinkles are an important visual cue for creating believably dressed characters in virtual environments. Adding these fine details to real-time cloth visualization is challenging, as the low-quality cloth ...
Divergence-Free and Boundary-Respecting Velocity Interpolation Using Stream Functions
(ACM, 2019)
In grid-based fluid simulation, discrete incompressibility of each cell is enforced by the pressure projection. However, pointwise velocities constructed by interpolating the discrete velocity samples from the staggered ...
Small Steps in Physics Simulation
(ACM, 2019)
In this paper we re-examine the idea that implicit integrators with large time steps offer the best stability/performance trade-off for stiff systems. We make the surprising observation that performing a single large time ...
Deployable 3D Linkages with Collision Avoidance
(The Eurographics Association, 2016)
We present a pipeline that allows ordinary users to create deployable scissor linkages in arbitrary 3D shapes, whose mechanisms are inspired by Hoberman's Sphere. From an arbitrary 3D model and a few user inputs, our method ...
Multi-linear Data-Driven Dynamic Hair Model with Efficient Hair-Body Collision Handling
(The Eurographics Association, 2012)
We present a data-driven method for learning hair models that enables the creation and animation of many interactive virtual characters in real-time (for gaming, character pre-visualization and design). Our model has a ...
Constraint-Based Simulation of Adhesive Contact
(The Eurographics Association, 2010)
Dynamics with contact are often formulated as a constrained optimization problem. This approach allows handling in an integrated manner both non-penetration and frictional constraints. Following developments in the ...
Smoke Sheets for Graph-Structured Vortex Filaments
(The Eurographics Association, 2012)
Smoke is one of the core phenomena which fluid simulation techniques in computer graphics have attempted to capture. It is both well understood mathematically and important in lending realism to computer generated effects. ...
Cloning Crowd Motions
(The Eurographics Association, 2012)
This paper introduces a method to clone crowd motion data. Our goal is to efficiently animate large crowds from existing examples of motions of groups of characters by applying an enhanced copy and paste technique on them. ...
Enriching Coarse Interactive Elastic Objects with High-Resolution Data-Driven Deformations
(The Eurographics Association, 2012)
Efficient approximate deformation models allow to interactively simulate elastic objects. However, these approaches usually cannot reproduce the complex deformation behavior governed by geometric and material nonlinearities. ...
