  • Tracking Control for Streaming Input Motion Using Segmented Foot Model 

    Lee, Seokjae; Park, Hwangpil; Lee, Jehee (ACM Siggraph, 2015)
    Motion capture data has been widely used to make realistic animation. Especially, in physics-based character simulation, motion data provides plausible reference trajectory of the character. However, it requires post-processing ...

    Brown, George; Samii, Armin; O'Brien, James F.; Narain, Rahul (ACM Siggraph, 2015)
    We describe a method for converting an adaptively remeshed simulation of cloth into an animated mesh with fixed topology. The topology of the mesh may be specified by the user or computed automatically. In the latter case, ...
  • Trajectory-Free Reactive Stepping of Physics-based Character Using Momentum Control 

    Lee, Sukwon; Choi, Hyunchul; Jin, Taeil; Lee, Sung-Hee (ACM Siggraph, 2015)
    We introduce a trajectory-free reactive stepping controller using momentum control. The controller is characterized by moving passively in the direction of external pushes without attempting to follow some prescribed ...
  • Improving Naturalness of Locomotion of Many-Muscle Humanoids 

    Yu, Ri; Jo, Dongchul; Lee, Jehee (ACM Siggraph, 2015)
    For many decades, researchers have worked on the simulation of biped locomotion such as human walking. As simulation models have evolved, the simulation using a musculoskeletal model has also become possible [Lee et al. ...
  • Gaze Driven Animation of Eyes 

    Neog, Debanga Raj; Ranjan, Anurag; Cardoso, João L.; Pai, Dinesh K. (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 ...
  • Fast Cloth Simulation with Implicit Contact and Exact Coulomb Friction 

    Daviet, Gilles; Bertails-Descoubes, Florence; Casati, Romain (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 ...
  • Discovering Human Postures from Non-human Silhouette 

    Won, Jungdam; Lee, Jehee (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 ...
  • Eulerian-on-Lagrangian Cloth 

    Piddington, Kyle; Levin, David I.W.; Pai, Dinesh K.; Sueda, Shinjiro (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 ...
  • Constraint-based Wrinkle Simulation in Texture Space 

    Silva, Paulo; Rungjiratananon, Witawat; Elcott, Sharif; Driancourt, Remi; Igarashi, Takeo (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 ...
  • A Hybrid Crowd Simulation Framework Towards Modeling Behavior of Individual Avoidance of Crowds 

    Liu, Haiying; Yan, Zhixin; Lindeman, Robert W.; Ding, Gangyi; Huang, Tianyu (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 ...
  • Fully Automatic Generation of Anatomical Face Simulation Models 

    Cong, Matthew; Bao, Michael; E, Jane L.; Bhat, Kiran S.; Fedkiw, Ronald (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 ...
  • Sketch Abstractions for Character Posing 

    Hahn, Fabian; Mutzel, Frederik; Coros, Stelian; Thomaszewski, Bernhard; Nitti, Maurizio; Gross, Markus; Sumner, Robert W. (ACM Siggraph, 2015)
    We propose a sketch-based posing system for rigged 3D characters that allows artists to create custom sketch abstractions on top of a character's actual shape. A sketch abstraction is composed of rigged curves that form ...
  • Learning an Inverse Rig Mapping for Character Animation 

    Holden, Daniel; Saito, Jun; Komura, Taku (ACM Siggraph, 2015)
    We propose a general, real-time solution to the inversion of the rig function - the function which maps animation data from a character's rig to its skeleton. Animators design character movements in the space of an animation ...
  • A Material Point Method for Viscoelastic Fluids, Foams and Sponges 

    Ram, Daniel; Gast, Theodore; Jiang, Chenfanfu; Schroeder, Craig; Stomakhin, Alexey; Teran, Joseph; Kavehpour, Pirouz (ACM Siggraph, 2015)
    We present a new Material Point Method (MPM) for simulating viscoelastic fluids, foams and sponges. We design our discretization from the upper convected derivative terms in the evolution of the left Cauchy-Green elastic ...
  • Divergence-Free Smoothed Particle Hydrodynamics 

    Bender, Jan; Koschier, Dan (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 ...

    Bruneau, Julien; Pettré, Julien (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 ...
