    • Misconceptions of PD Control in Animation 

      Allen, Brian F.; Faloutsos, Petros (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 ...

    • Physically Plausible Simulation for Character Animation 

      Levine, Sergey; Popovic, Jovan (The Eurographics Association, 2012)
      Artist-created animated characters can exhibit stylized, engaging behavior, but require considerable effort to construct, while interactive applications require numerous motions and variations to create a dynamic, believable ...

    • Simple Data-Driven Control for Simulated Bipeds 

      Geijtenbeek, T.; Pronost, Nicolas; Stappen, A. F. van der (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 ...

    • Cloning Crowd Motions 

      Li, Yi; Christie, Marc; Siret, Orianne; Kulpa, Richard; Pettré, Julien (The Eurographics Association, 2012)
      This paper introduces a method to clone crowd motion data. Our goal is to efficiently animate large crowds from existing examples of motions of groups of characters by applying an enhanced copy and paste technique on them. ...

    • Quaternion Space Sparse Decomposition for Motion Compression and Retrieval 

      Zhu, Mingyang; Sun, Huaijiang; Deng, Zhigang (The Eurographics Association, 2012)
      Quaternion has become one of the most widely used representations for rotational transformations in 3D graphics for decades. Due to the sparse nature of human motion in both the spatial domain and the temporal domain, an ...

    • Environment-aware Real-Time Crowd Control 

      Henry, Joseph; Shum, Hubert P. H.; Komura, Taku (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 ...

    • Evaluating the Plausibility of Edited Throwing Animations 

      Vicovaro, Michele; Hoyet, Ludovic; Burigana, Luigi; O'Sullivan, Carol (The Eurographics Association, 2012)
      Animation budget constraints during the development of a game often call for the use of a limited set of generic motions. Editing operations are thus generally required to animate virtual characters with a sufficient level ...

    • Component-based Locomotion Composition 

      Kim, Yejin; Neff, Michael (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. ...

    • Learning Motion Controllers with Adaptive Depth Perception 

      Lo, Wan-Yen; Knaus, Claude; Zwicker, Matthias (The Eurographics Association, 2012)
      We present a novel approach to real-time character animation that allows a character to move autonomously based on vision input. By allowing the character to ''see'' the environment directly using depth perception, we can ...

    • Task-driven Posture Optimization for Virtual Characters 

      Liu, Mingxing; Micaelli, Alain; Evrard, Paul; Escande, Adrien (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 ...

    • Contact-Invariant Optimization for Hand Manipulation 

      Mordatch, Igor; Popovic, Zoran; Todorov, Emanuel (The Eurographics Association, 2012)
      We present a method for automatic synthesis of dexterous hand movements, given only high-level goals specifying what should happen to the object being manipulated. Results are presented on a wide range of tasks including ...

    • Precomputed Motion Maps for Unstructured Motion Capture 

      Mahmudi, Mentar; Kallmann, Marcelo (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 ...

    • Simulating Free Surface Flow with Very Large Time Steps 

      Lentine, Michael; Cong, Matthew; Patkar, Saket; Fedkiw, Ronald (The Eurographics Association, 2012)
      We provide a novel simulation method for incompressible free surface flows that allows for large time steps on the order of 10-40 times bigger than the typical explicit time step restriction would allow. Although semi-Lagrangian ...

    • Tiling Motion Patches 

      Kim, Manmyung; Hwang, Youngseok; Hyun, Kyunglyul; Lee, Jehee (The Eurographics Association, 2012)
      Simulating multiple character interaction is challenging because character actions must be carefully coordinated to align their spatial locations and synchronized with each other. We present an algorithm to create a dense ...
