TECHNICAL PAPERS AND SESSIONS
Motion Synthesis and Editing (TOG)
Wednesday, 5 August | 8:30 AM - 10:15 AM | Hall E 3
Optimization-Based Interactive Motion Synthesis
A physics-based approach to synthesizing motion of a responsive virtual character in a dynamically varying environment. This framework allows the programmer to specify active control strategies using intuitive kinematic goals that are encoded as objectives and constraints in the optimization problem formulated at each time step.

Character Animation I
Thursday, 6 August | 8:30 AM - 10:15 AM | Hall E 1-2
Dextrous Manipulation From a Grasping Pose
This paper describes an automatic algorithm that takes as input an initial grasping pose and partial object trajectory, and produces as output a physically plausible hand animation that effects the desired manipulation.

Performance-Based Control Interface for Character Animation
A system that directly uses human motion performance to provide a radically different, and much more expressive interface for controlling virtual characters.

Modeling and Rendering of Dynamic Shapes (TOG)
Thursday, 6 August | 1:45 PM - 3:30 PM | Hall E 3
Fitting Solid Meshes to Animated Surfaces Using Linear Elasticity
Computing correspondence between time frames of an animated 3D surface is essential for understanding its motion. This paper presents a method that can produce correspondence information for objects that do not undergo large volume or topological changes, such as living creatures, based on linear elasticity with rotation compensation.

Meshing
Friday, 7 August | 8:30 AM - 10:15 AM | Hall E 1-2
Deforming Meshes That Split and Merge
A method for accurately tracking the moving surface of deformable materials, represented by a triangle mesh, in a manner that gracefully handles topological changes. In regions where topological events are detected, the method inserts a simplified surface created with a standard isosurface-creation method.

Physically Based Modeling: From Contact to Capture
Friday, 7 August | 1:45 PM - 3:30 PM | Hall E 1-2
Physically Guided Liquid Surface Modeling From Videos
This paper presents an image-based reconstruction framework to model real liquid scenes captured by stereoscopic video. The algorithm combines stereo reconstruction with automatically calculated, physically based constraints, which allows effective modeling of complex and dynamic objects such as fluids.

The Art History of Games
Thursday, 6 August | 8:30 AM - 10:15 AM | Auditorium C
This panel explores ideas surrounding games as an art form, the role of technology in the development of games and the relationship among games, the established art world, "fine art" forms, and the cultural traditions of art.
