    • High Fidelity Facial Animation Capture and Retargeting With Contours 

      Bhat, Kiran S.; Goldenthal, Rony; Ye, Yuting; Mallet, Ronald; Koperwas, Michael (ACM SIGGRAPH / Eurographics Association, 2013)
      Human beings are naturally sensitive to subtle cues in facial expressions, especially in areas of the eyes and mouth. Current facial motion capture methods fail to accurately reproduce motions in those areas due to multiple ...
    • Data-driven Glove Calibration for Hand Motion Capture 

      Wang, Yingying; Neff, Michael (ACM SIGGRAPH / Eurographics Association, 2013)
      Hand motion is an important component of human motion, playing a central role in communication. However, it is difficult to capture hand motion optically, especially in conjunction with full body motion. Due to a lack of ...

      Huang, Pengfei; Kapadia, Mubbasir; Badler, Norman I. (ACM SIGGRAPH / Eurographics Association, 2013)
      The perception of sensory information and its impact on behavior is a fundamental component of being human. While visual perception is considered for navigation, collision, and behavior selection, the acoustic domain is ...
    • Virtual Character Performance From Speech 

      Marsella, Stacy; Xu, Yuyu; Lhommet, Margaux; Feng, Andrew; Scherer, Stefan; Shapirok, Ari (ACM SIGGRAPH / Eurographics Association, 2013)
      We demonstrate a method for generating a 3D virtual character performance from the audio signal by inferring the acoustic and semantic properties of the utterance. Through a prosodic analysis of the acoustic signal, we ...
    • Artistic Simulation of Curly Hair 

      Iben, Hayley; Meyer, Mark; Petrovic, Lena; Soares, Olivier; Anderson, John; Witkin, Andrew (ACM SIGGRAPH / Eurographics Association, 2013)
      Artistic simulation of hair presents many challenges - ranging from incorporating artistic control to dealing with extreme motions of characters. Additionally, in a production environment, the simulation needs to be fast ...
    • Relationship Descriptors for Interactive Motion Adaptation 

      Al-Asqhar, Rami Ali; Komura, Taku; Choi, Myung Geol (ACM SIGGRAPH / Eurographics Association, 2013)
      This paper presents an interactive motion adaptation scheme for close interactions between skeletal characters and mesh structures, such as moving through restricted environments, and manipulating objects. This is achieved ...
    • One-to-Many: Example-Based Mesh Animation Synthesis 

      Zheng, Changxi (ACM SIGGRAPH / Eurographics Association, 2013)
      We propose an example-based approach for synthesizing diverse mesh animations. Provided a short clip of deformable mesh animation, our method synthesizes a large number of different animations of arbitrary length. Combining ...
    • Geodesic Voxel Binding for Production Character Meshes 

      Dionne, Olivier; Lasa, Martin de (ACM SIGGRAPH / Eurographics Association, 2013)
      We propose a fully automatic method for specifying influence weights for closed-form skinning methods, such as linear blend skinning. Our method is designed to work with production meshes that may contain non-manifold ...
    • Diverse Motion Variations for Physics-based Character Animation 

      Agrawal, Shailen; Shen, Shuo; Panne, Michiel van de (ACM SIGGRAPH / Eurographics Association, 2013)
      We present an optimization framework for generating diverse variations of physics-based character motions. This allows for the automatic synthesis of rich variations in style for simulated jumps, flips, and walks. While ...
    • Multi-Domain Real-time Planning in Dynamic Environments 

      Kapadia, Mubbasir; Beacco, Alejandro; Garcia, Francisco; Reddy, Vivek; Pelechano, Nuria; Badler, Norman I. (ACM SIGGRAPH / Eurographics Association, 2013)

    • Rod Constraints for Simplified Ragdolls 

      Lewin, Chris; Thorman, Matt; Waterson, Tom; Williams, Chris; Willis, Phil (ACM SIGGRAPH / Eurographics Association, 2013)
      Physics-based animation has become a standard feature in modern games. Typically, the bones in a character's animation rig are each associated with a simulated rigid body, leading to a jointed assembly commonly called a ...
