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 ...
Linear-Time Smoke Animation with Vortex Sheet Meshes
(The Eurographics Association, 2012)
We present the first quality physics-based smoke animation method which runs in time approximately linear in the size of the rendered two-dimensional visual detail. Our fundamental representation is a closed triangle mesh ...
Dynamic Units of Visual Speech
(The Eurographics Association, 2012)
We present a new method for generating a dynamic, concatenative, unit of visual speech that can generate realistic visual speech animation. We redefine visemes as temporal units that describe distinctive speech movements ...
Principal Geodesic Dynamics
(The Eurographics Association, 2012)
This paper presents a new integration of a data-driven approach using dimension reduction and a physicallybased simulation for real-time character animation. We exploit Lie group statistical analysis techniques (Principal ...
Component-based Locomotion Composition
(The Eurographics Association, 2012)
When generating locomotion, it is particularly challenging to adjust the motion's style. This paper introduces a component-based system for human locomotion composition that drives off a set of example locomotion clips. ...
Simple Data-Driven Control for Simulated Bipeds
(The Eurographics Association, 2012)
We present a framework for controlling physics-based bipeds in a simulated environment, based on a variety of reference motions. Unlike existing methods for control based on reference motions, our framework does not require ...
Combining Marker-based Mocap and RGB-D Camera for Acquiring High-fidelity Hand Motion Data
(The Eurographics Association, 2012)
Motion capture data has been pivotal to the success of creating realistic animation for human characters. There are a number of public full-body motion databases available, but large and heterogeneous databases for hand ...
Environment-aware Real-Time Crowd Control
(The Eurographics Association, 2012)
Real-time crowd control has become an important research topic due to the recent advancement in console game quality and hardware processing capability. The degrees of freedom of a crowd is much higher than that provided ...
Task-driven Posture Optimization for Virtual Characters
(The Eurographics Association, 2012)
This paper presents a generic approach to find optimal postures, including contact positions, for manipulation tasks. It can be used in either the preparation for a task, or the evaluation of the feasibility of a task ...
Precomputed Motion Maps for Unstructured Motion Capture
(The Eurographics Association, 2012)
We present in this paper a solution for extracting high-quality motions from unstructured motion capture databases at interactive rates. The proposed solution is based on automatically-built motion graphs, and offers two ...
