MAAIP: Multi-Agent Adversarial Interaction Priors for imitation from fighting demonstrations for physics-based characters
(ACM Association for Computing Machinery, 2023)Simulating realistic interaction and motions for physics-based characters is of great interest for interactive applications, and automatic secondary character animation in the movie and video game industries. Recent works ... -
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 ... -
Mapping optical motion capture data to skeletal motion using a physical model
(The Eurographics Association, 2003)Motion capture has become a premiere technique for animation of humanlike characters. To facilitate its use, researchers have focused on the manipulation of data for retargeting, editing, combining, and reusing motion ... -
Mass and Momentum Conservation for Fluid Simulation
(The Eurographics Association, 2011)Momentum conservation has long been used as a design principle for solid simulation (e.g. collisions between rigid bodies, mass-spring elastic and damping forces, etc.), yet it has not been widely used for fluid simulation. ... -
Mass-Conserving Eulerian Liquid Simulation
(The Eurographics Association, 2012)We present a GPU friendly, Eulerian, free surface fluid simulation method that conserves mass locally and globally without the use of Lagrangian components. Local mass conservation prevents small scale details of the free ... -
A Material Point Method for Viscoelastic Fluids, Foams and Sponges
(ACM Siggraph, 2015)We present a new Material Point Method (MPM) for simulating viscoelastic fluids, foams and sponges. We design our discretization from the upper convected derivative terms in the evolution of the left Cauchy-Green elastic ... -
Mathematical Analysis on Affine Maps for 2D Shape Interpolation
(The Eurographics Association, 2012)This paper gives a simple mathematical framework for 2D shape interpolation methods that preserve rigidity. An interpolation technique in this framework works for given the source and target 2D shapes, which are compatibly ... -
Mathematical Foundation of the Optimization-based Fluid Animation Method
(The Eurographics Association, 2011)We present the mathematical foundation of a fluid animation method for unstructured meshes. Key contributions not previously treated are the extension to include diffusion forces and higher order terms of non-linear force ... -
Meshless Modeling of Deformable Shapes and their Motion
(The Eurographics Association, 2008)We present a new framework for interactive shape deformation modeling and key frame interpolation based on a meshless finite element formulation. Starting from a coarse nodal sampling of an object's volume, we formulate ... -
Methods for Exploring Expressive Stance
(The Eurographics Association, 2004)The postures a character adopts over time are a key expressive aspect of her movement. While IK tools help a character achieve positioning constraints, there are few tools that help an animator with the expressive aspects ... -
Micropolar Elasticity in Physically-Based Animation
(ACM Association for Computing Machinery, 2023)We explore micropolar materials for the simulation of volumetric deformable solids. In graphics, micropolar models have only been used in the form of one-dimensional Cosserat rods, where a rotating frame is attached to ... -
A Micropolar Material Model for Turbulent SPH Fluids
(ACM, 2017)In this paper we introduce a novel micropolar material model for the simulation of turbulent inviscid fluids. The governing equations are solved by using the concept of Smoothed Particle Hydrodynamics (SPH). As already ... -
Misconceptions of PD Control in Animation
(The Eurographics Association, 2012)In this paper, we address certain misconceptions that have been perpetuated in the animation practice and research for quite some time related to the proportional-derivative (PD) control of physics-based systems. Because ... -
Modeling and Animating Gases with Simulation Features
(The Eurographics Association, 2005)In modeling natural phenomena, artists often compromise the benefits of direct control for the visual realism of physics-based simulation. For gases, Eulerian simulations traditionally provide realistic results, but a poor ... -
Modeling and Animating Myriapoda: A Real-Time Kinematic/Dynamic Approach
(ACM SIGGRAPH / Eurographics Association, 2013)Unlike two, four, six, and eight legged animals, Myriapoda-i.e., centipedes, millipedes, etc.-have been largely overlooked in the computer graphics literature. We present an artificial life framework for modeling these ... -
Modeling and Data-Driven Parameter Estimation for Woven Fabrics
(ACM, 2017)Accurate estimation of mechanical parameters for simulation of woven fabrics is essential in many fields. To facilitate this we first present a new orthotropic hyperelastic constitutive model for woven fabrics. Next, we ... -
Modeling and Editing Flows Using Advected Radial Basis Functions
(The Eurographics Association, 2004)Fluid simulations are notoriously difficult to predict and control. As a result, authoring fluid flows often involves a tedious trial and error process. There is to date no convenient way of editing a fluid after it has ... -
Modeling Deformable Human Hands from Medical Images
(The Eurographics Association, 2004)This paper presents a new method for constructing an example-based deformable human hand model from medical images. Realistic animation of human hands requires good estimates of the joint structure and properly weighted ... -
Modeling Ice Dynamics As A Thin-Film Stefan Problem
(The Eurographics Association, 2006)Large, 3D ice formations such as icicles exhibit a high degree of geometric and optical complexity. Modeling these features by hand can be a daunting task, so we present a novel physically-based algorithm for simulating ... -
Modeling Style and Variation in Human Motion
(The Eurographics Association, 2010)Style and variation are two vital components of human motion: style differentiates between examples of the same behavior (slow walk vs. fast walk) while variation differentiates between examples of the same style (vigorous ...
