      Thomaszewski, Bernhard; Wacker, Markus; Straßer, Wolfgang (The Eurographics Association, 2006)
      Wrinkles and folds play an important role in the appearance of real textiles. The way in which they form depends mainly on the bending properties of the specific material type. Existing approaches fail to reliably reproduce ...

      We present an efficient algorithm for simulating contacts between deformable bodies with high-resolution surface geometry using dynamic deformation textures, which reformulate the 3D elastoplastic deformation and collision ...
    • Fat Graphs: Constructing an Interactive Character with Continuous Controls 

      Shin, Hyun Joon; Oh, Hyun Seok (The Eurographics Association, 2006)
      This paper proposes a methodology that allows users to control character s motion interactively but continuously. Inspired by the work of Gleicher et al. [GSKJ03], we propose a semi-automatic method to build fat graphs ...
    • Generating Surface Crack Patterns 

      Iben, Hayley N.; O'Brien, James F. (The Eurographics Association, 2006)
      We present a method for generating surface crack patterns that appear in materials such as mud, ceramic glaze, and glass. To model these phenomena, we build upon existing physically based methods. Our algorithm generates ...
    • Geometric, Variational Integrators for Computer Animation 

      Kharevych, Liliya; Yang, Weiwei; Tong, Yiying; Kanso, Eva; Marsden, Jerrold E.; Schröder, Peter; Desbrun, Matthieu (The Eurographics Association, 2006)
      We present a general-purpose numerical scheme for time integration of Lagrangian dynamical systems an important computational tool at the core of most physics-based animation techniques. Several features make this particular ...
    • Hierarchical Retargetting of 2D Motion Fields to the Animation of 3D Plant Models 

      Diener, Julien; Reveret, Lionel; Fiume, Eugene (The Eurographics Association, 2006)
      The complexity of animating trees, shrubs and foliage is an impediment to the efficient and realistic depiction of natural environments. This paper presents an algorithm to extract, from a single video sequence, motion ...
    • Interactive Animation of Dynamic Manipulation 

      Abe, Yeuhi; Popovic, Jovan (The Eurographics Association, 2006)
      Lifelike animation of object manipulation requires dynamic interaction between animated characters, objects, and their environment. These interactions can be animated automatically with physically based simulations but ...
    • Keyframe Control of Complex Particle Systems Using the Adjoint Method 

      Wojtan, Chris; Mucha, Peter J.; Turk, Greg (The Eurographics Association, 2006)
      Control of physical simulation has become a popular topic in the field of computer graphics. Keyframe control has been applied to simulations of rigid bodies, smoke, liquid, flocks, and finite element-based elastic bodies. ...
