Animating Articulated Characters using Wiggly Splines
(ACM Siggraph, 2015)We propose a new framework for spacetime optimization that can generate artistic motion with a long planning horizon for complex virtual characters. The scheme can be used for generating general types of motion and neither ... -
BSwarm: Biologically-Plausible Dynamics Model of Insect Swarms
(ACM Siggraph, 2015)We present a biologically plausible dynamics model to simulate swarms of flying insects. Our formulation, which is based on biological conclusions and experimental observations, is designed to simulate large insect swarms ... -
Computational Design of Walking Automata
(ACM Siggraph, 2015)Creating mechanical automata that can walk in stable and pleasing manners is a challenging task that requires both skill and expertise. We propose to use computational design to offset the technical difficulties of this ... -
Constraint-based Wrinkle Simulation in Texture Space
(ACM Siggraph, 2015)An important factor in increasing realism of synthetic images, wrinkles have received a considerable amount of attention from the computer graphics research community. The method Wrinkle Meshes, targets real-time simulation ... -
Discovering Human Postures from Non-human Silhouette
(ACM Siggraph, 2015)The shadow theatre is an unique performing arts, which utilizes a shadow as an main communication tool. This can be understood easily by an extension of traditional shadow play. Key difference comes from the fact that ... -
Divergence-Free Smoothed Particle Hydrodynamics
(ACM Siggraph, 2015)In this paper we introduce an efficient and stable implicit SPH method for the physically-based simulation of incompressible fluids. In the area of computer graphics the most efficient SPH approaches focus solely on the ... -
Effect of Appearance on Perception of Deformation
(ACM Siggraph, 2015)We provide an experimental validation that appearance of an object can influence the perception of its level of deformation in a 3D simulation. Our study provides helpful insights in how to improve visual plausibility of ... -
Efficient Simulation of Knitted Cloth Using Persistent Contacts
(ACM Siggraph, 2015)Knitted cloth is made of yarns that are stitched in regular patterns, and its macroscopic behavior is dictated by the contact interactions between such yarns. We propose an efficient representation of knitted cloth at the ... -
Energy-efficient mid-term strategies for collision avoidance in crowd simulation
(ACM Siggraph, 2015)When navigating in crowds, humans are able to move efficiently between people. They look ahead to know which path would reduce the complexity of their interactions with others. Current navigation systems for virtual agents ... -
Eulerian-on-Lagrangian Cloth
(ACM Siggraph, 2015)We present a new, Eulerian-on-Lagrangian approach for modeling cloth. When a cloth modeled using the traditional Lagrangian approach is moved around an object with sharp corners, such as the edge of a table, the cloth ... -
Fast Cloth Simulation with Implicit Contact and Exact Coulomb Friction
(ACM Siggraph, 2015)Cloth dynamics plays a major role in the visual appearance of moving characters. Properly accounting for frictional contact is of utmost importance to avoid cloth-body penetration and to capture folding behavior due to dry ... -
Fully Automatic Generation of Anatomical Face Simulation Models
(ACM Siggraph, 2015)We present a fast, fully automatic morphing algorithm for creating simulatable flesh and muscle models for human and humanoid faces. Current techniques for creating such models require a significant amount of time and ... -
Fully Momentum-Conserving Reduced Deformable Bodies with Collision, Contact, Articulation, and Skinning
(ACM Siggraph, 2015)We propose a novel framework for simulating reduced deformable bodies that fully accounts for linear and angular momentum conservation even in the presence of collision, contact, articulation, and other desirable effects. ... -
Functional Thin Films on Surfaces
(ACM Siggraph, 2015)The motion of a thin viscous film of fluid on a curved surface exhibits many intricate visual phenomena, which are challenging to simulate using existing techniques. A possible alternative is to use a reduced model, involving ... -
Gaze Driven Animation of Eyes
(ACM Siggraph, 2015)We present a data driven model of eye movement, that includes movement of the globes, the periorbital soft tissues and eyelids and also the formation of wrinkles in the tissues. We describe a pipeline for measurement and ... -
Hands On: Interactive Animation of Precision Manipulation and Contact
(ACM Siggraph, 2015)Humans show effortless dexterity while manipulating objects using their own hands. However, specifying the motion of a virtual character's hand or of a robotic manipulator remains a difficult task that requires animation ... -

A Hybrid Crowd Simulation Framework Towards Modeling Behavior of Individual Avoidance of Crowds
(ACM Siggraph, 2015)Crowd movement is a common but complicated phenomenon in our daily lives. The behaviors of crowds can be affected by both individual and crowd. Most previous research could be categorized as either agent-based methods [van ... -
Improving Naturalness of Locomotion of Many-Muscle Humanoids
