    • Synchronization for dynamic blending of motions 

      Ménardais, Stéphane; Kulpa, Richard; Multon, Franck; Arnaldi, Bruno (The Eurographics Association, 2004)
      In this paper we present a new real-time synchronization algorithm. In dynamic environments, motions need to be continuously adapted to obtain realistic animations. We propose an advanced time warping algorithm to synchronize ...
    • Animation and Control of Breaking Waves 

      Mihalef, Viorel; Metaxas, Dimitris; Sussman, Mark (The Eurographics Association, 2004)
      Controlling fluids is still an open and challenging problem in fluid animation. In this paper we develop a novel fluid animation control approach and we present its application to controlling breaking waves. In our Slice ...
    • A Hybrid Algorithm for Modeling Ice Formation 

      Kim, Theodore; Henson, Michael; Lin, Ming C. (The Eurographics Association, 2004)
      We present a novel algorithm that simulates ice formation. Motivated by the physical process of ice growth, we develop a novel hybrid algorithm by synthesizing three techniques: diffusion limited aggregation, phase field ...
    • Simulation Levels of Detail for Plant Motion 

      Beaudoin, Jacob; Keyser, John (The Eurographics Association, 2004)
      In this paper we describe a method for simulating motion of realistically complex plants interactively. We use a precomputation stage to generate the plant structure, along with a set of simulation levels of detail. The ...
    • Better with Bubbles: Enhancing the Visual Realism of Simulated Fluid 

      Greenwood, Shannon T.; House, Donald H. (The Eurographics Association, 2004)
      We present a method for including the visual effect of bubbles in a computer graphics fluid simulation, thus enhancing the illusion of realism for a splashing fluid. Previous fluid simulation methods have not included ...
    • Animal gaits from video 

      Favreau, Laurent; Reveret, Lionel; Depraz, Christine; Cani, Marie-Paule (The Eurographics Association, 2004)
      We present a method for animating 3D models of animals from existing live video sequences such as wild life documentaries. Videos are first segmented into binary images on which Principal Component Analysis (PCA) is applied. ...
    • Motion Map: Image-based Retrieval and Segmentation of Motion Data 

      Sakamoto, Yasuhiko; Kuriyama, Shigeru; Kaneko, Toyohisa (The Eurographics Association, 2004)
      Recent proliferation of motion capture systems enables motion data to be saved as an archive system, and the data are usually extracted by selecting an appropriate file by its name or annotation explaining the content of ...
    • Cartoon Textures 

      Juan, Christina de; Bodenheimer, Bobby (The Eurographics Association, 2004)
      In this paper we present a method for creating novel animations from a library of existing two-dimensional cartoon data. Drawing inspiration from the idea of video textures, sequences of similar-looking cartoon data are ...
    • Performance Timing for Keyframe Animation 

      Terra, Silvio C. L.; Metoyer, Ronald A. (The Eurographics Association, 2004)
      Keyframing is a standard technique for generating computer animation that typically requires artistic ability and a set of skills for the software package being used. We are interested in addressing the needs of the novice ...
    • Crowdbrush: Interactive Authoring of Real-time Crowd Scenes 

      Ulicny, Branislav; Ciechomski, Pablo de Heras; Thalmann, Daniel (The Eurographics Association, 2004)
      Recent advances in computer graphics techniques and increasing power of graphics hardware made it possible to display and animate large crowds in real-time. Most of the research efforts have been directed towards improving ...
    • Flow Tiles 

      Chenney, Stephen (The Eurographics Association, 2004)
      We present flow tiles, a novel technique for representing and designing velocity fields. Unlike existing procedural flow generators, tiling offers a natural user interface for field design. Tilings can be constructed to ...
    • Modeling and Editing Flows Using Advected Radial Basis Functions 

      Pighin, Frédéric; Cohen, Jonathan M.; Shah, Maurya (The Eurographics Association, 2004)
      Fluid simulations are notoriously difficult to predict and control. As a result, authoring fluid flows often involves a tedious trial and error process. There is to date no convenient way of editing a fluid after it has ...
    • Extended Galilean Invariance for Adaptive Fluid Simulation 

      Shah, Maurya; Cohen, Jonathan M.; Patel, Sanjit; Lee, Penne; Pighin, Frédéric (The Eurographics Association, 2004)
      In an unbounded physical domain, simulating a turbulent fluid on an Eulerian grid is rather tricky. Since it is difficult to predict the motion of the fluid, it is also difficult to guess which computational domain would ...
    • Animation of Reactive Gaseous Fluids through Chemical Kinetics 

      Ihm, Insung; Kang, Byungkwon; Cha, Deukhyun (The Eurographics Association, 2004)
      Although chemically reactive fluids may be used effectively to increase the reality of visual effects, little work has been done with the general modeling of chemical reactions in computer animation. In this paper, we ...
    • Directable Photorealistic Liquids 

      Rasmussen, Nick; Enright, Doug; Nguyen, Duc; Marino, Sebastian; Sumner, Nigel; Geiger, Willi; Hoon, Samir; Fedkiw, Ron (The Eurographics Association, 2004)
      We present a method for the directable animation of photorealistic liquids using the particle level set method to obtain smooth, visually pleasing complex liquid surfaces. We also provide for a degree of control common to ...
