Statistical Simulation of Rigid Bodies
(ACM SIGGRAPH / Eurographics Association, 2009)
We describe a method for replacing certain stages of rigid body simulation with a statistically-based approximation. We begin by collecting statistical data regarding changes in linear and angular momentum for collisions ...
A Point-based Method for Animating Incompressible Flow
(ACM SIGGRAPH / Eurographics Association, 2009)
In this paper, we present a point-based method for animating incompressible flow. The advection term is handled by moving the sample points through the flow in a Lagrangian fashion. However, unlike most previous approaches, ...
Real-Time Deformation and Fracture in a Game Environment
(ACM SIGGRAPH / Eurographics Association, 2009)
This paper describes a simulation system that has been developed to model the deformation and fracture of solid objects in a real-time gaming context. Based around a corotational tetrahedral finite element method, this ...
Simulating Balance Recovery Responses to Trips Based on Biomechanical Principles
(ACM SIGGRAPH / Eurographics Association, 2009)
To realize the full potential of human simulations in interactive environments, we need controllers that have the ability to respond appropriately to unexpected events. In this paper, we create controllers for the trip ...
Anisotropic Friction for Deformable Surfaces and Solids
(ACM SIGGRAPH / Eurographics Association, 2009)
This paper presents a method for simulating anisotropic friction for deforming surfaces and solids. Frictional contact is a complex phenomenon that fuels research in mechanical engineering, computational contact mechanics, ...
Style Learning and Transferring for Facial Animation Editing
(ACM SIGGRAPH / Eurographics Association, 2009)
Most of current facial animation editing techniques are frame-based approaches (i.e., manually edit one keyframe every several frames), which is ineffective, time-consuming, and prone to editing inconsistency. In this ...
A Point-Based Method for Animating Elastoplastic Solids
(ACM SIGGRAPH / Eurographics Association, 2009)
In this paper we describe a point-based approach for animating elastoplastic materials. Our primary contribution is a simple method for computing the deformation gradient for each particle in the simulation. The deformation ...
Exact volume preserving skinning with shape control
(ACM SIGGRAPH / Eurographics Association, 2009)
In the real world, most objects do not loose volume when they deform: they may for instance compensate a local compression by inflating in the orthogonal direction, or, in the case of a character, preserve volume through ...
Fitting Behaviors to Pedestrian Simulations
(ACM SIGGRAPH / Eurographics Association, 2009)
In this paper we present a data-driven approach for fitting behaviors to simulated pedestrian crowds. Our method annotates agent trajectories, generated by any crowd simulator, with action-tags. The aggregate effect of ...
