Simulating Complex Hair with Robust Collision Handling
(The Eurographics Association, 2005)We present a new framework for simulating dynamic movements of complex hairstyles. The proposed framework, which treats hair as a collection of wisps, includes new approaches to simulating dynamic wisp movements and handling ... -
Transferable Videorealistic Speech Animation
(The Eurographics Association, 2005)Image-based videorealistic speech animation achieves significant visual realism at the cost of the collection of a large 5- to 10-minute video corpus from the specific person to be animated. This requirement hinders its ... -
An Art-Directed Wrinkle System for CG Character Clothing
(The Eurographics Association, 2005)We present a kinematic system for creating art-directed wrinkles on costumes for CG characters. This system employs a curve-based method for creating wrinkles on reference poses, which are incorporated into a weighted ... -
Directable Animation of Elastic Objects
(The Eurographics Association, 2005)There is a crucial demand in the computer animation industry to make animations that blend animator-specified expressive motion with physics-based realism. We propose a novel framework to create directable animation of ... -
Morphable model of quadrupeds skeletons for animating 3D animals
(The Eurographics Association, 2005)Skeletons are at the core of 3D character animation. The goal of this work is to design a morphable model of 3D skeleton for four footed animals, controlled by a few intuitive parameters. This model enables the automatic ... -
Spatial Keyframing for Performance-driven Animation
(The Eurographics Association, 2005)This paper introduces spatial keyframing, a technique for performance-driven character animation. In traditional temporal keyframing, key poses are defined at specific points in time: i.e., we define a map from a set of ... -
Simulation of Smoke based on Vortex Filament Primitives
(The Eurographics Association, 2005)We describe a method that permits the high performance simulation of fluid phenomena such as smoke, with highlevel control for the artist. Our key primitives are vortex filament and vortex ring: vorticity defines a flow ... -
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 ... -
Pushing People Around
(The Eurographics Association, 2005)We present an algorithm for animating characters being pushed by an external source such as a user or a game environment. We start with a collection of motions of a real person responding to being pushed. When a character ... -
An Efficient Search Algorithm for Motion Data Using Weighted PCA
(The Eurographics Association, 2005)Good motion data is costly to create. Such an expense often makes the reuse of motion data through transformation and retargetting a more attractive option than creating new motion from scratch. Reuse requires the ability ... -
Particle-Based Simulation of Granular Materials
(The Eurographics Association, 2005)Granular materials, such as sand and grains, are ubiquitous. Simulating the 3D dynamic motion of such materials represents a challenging problem in graphics because of their unique physical properties. In this paper we ... -
Capture and Synthesis of Insect Motion
(The Eurographics Association, 2005)We present an integrated system that enables the capture and synthesis of 3D motions of small scale dynamic creatures, typically insects and arachnids, in order to drive computer generated models. The system consists of a ... -
Motion Modeling for On-Line Locomotion Synthesis
(The Eurographics Association, 2005)In this paper, we propose an example-based approach to on-line locomotion synthesis. Our approach consists of two parts: motion analysis and motion synthesis. In the motion analysis part, an unlabeled motion sequence is ... -
Video-Based Character Animation
(The Eurographics Association, 2005)In this paper we introduce a video-based representation for free viewpoint visualization and motion control of 3D character models created from multiple view video sequences of real people. Previous approaches to videobased ... -
Autonomous Pedestrians
(The Eurographics Association, 2005)We address the difficult open problem of emulating the rich complexity of real pedestrians in urban environments. Our artificial life approach integrates motor, perceptual, behavioral, and cognitive components within a ... -
Imitation as a First Step to Social Learning in Synthetic Characters: A Graph-based Approach
(The Eurographics Association, 2005)The processes and representations used to generate the behavior of expressive virtual characters are a valuable and largely untapped resource for helping those characters make sense of the world around them. In this paper, ... -
Image-Based Tomographic Reconstruction of Flames
(The Eurographics Association, 2004)Non-invasively determining the three-dimensional structure of real flames is a challenging task. We present a tomographic method for reconstructing a volumetric model from multiple images of fire. The method is similar to ... -
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 ... -
Real-time Speech Motion Synthesis from Recorded Motions
(The Eurographics Association, 2004)Data-driven approaches have been successfully used for realistic visual speech synthesis. However, little effort has been devoted to real-time lip-synching for interactive applications. In particular, algorithms that are ... -
Computing the Duration of Motion Transitions: An Empirical Approach
(The Eurographics Association, 2004)This paper develops methods for determining a visually appealing length for a motion transition, i.e., a segue between two sequences of character animation. Motion transitions are an important component in generating ...
