  • Topological Operations for Geomorphological Evolution 

    Bezin, Richard; Crespin, Benoit; Skapin, Xavier; Terraz, Olivier; Meseure, Philippe (The Eurographics Association, 2011)
    Geomorphological processes sculpt the shape of our everyday landscapes and must therefore be simulated to generate plausible digital landscapes. In particular, topological changes must be taken into account during the ...

  • Generating Large-scale Details: Altering Soil Surface and Structure with Tracks 

    Peyrat, Alexandre; Terraz, Olivier; Merillou, Stephane; Galin, Eric; Ghazanfarpour, Djamchid (The Eurographics Association, 2011)
    Tracks, footsteps and ruts are common elements we can observe in natural sceneries. Wherever there is human activity, we can find marks on the ground left by vehicles or walkers. These marks can be directly dug from a soft ...

  • Focused Ultrasound - Efficient GPU Simulation Methods for Therapy Planning 

    Georgii, Joachim; Dresky, Caroline von; Meier, Sebastian; Demedts, Daniel; Schumann, Christian; Preusser, Tobias (The Eurographics Association, 2011)
    Over the past years, high intensity focused ultrasound therapy has become a promising therapeutic alternative for non-invasive tumor treatment. The basic idea of this interventional approach is to apply focused ultrasound ...

  • Data-Driven Completion of Motion Capture Data 

    Baumann, Jan; Krüger, Björn; Zinke, Arno; Weber, Andreas (The Eurographics Association, 2011)
    We present a data-driven method for completion of corrupted marker-based motion capture data. Our novel approach is especially suitable for challenging cases, e.g. if complete marker sets of multiple body parts are missing ...

  • Introducing Congestion Avoidance into CUDA Based Crowd Simulation 

    Wockenfuss, Falco; Lürig, Christoph (The Eurographics Association, 2011)
    The simulation of larger crowds of peoples at interactive frames rates get more and more important in games and interactive simulations. Crowds contribute significantly to an immersive urban environment. The nature of the ...

  • Methods for Measuring State Error for Control of Animated Human Figures 

    Notman, Gabriel; Carlisle, P. A.; Manning, S. (The Eurographics Association, 2011)
    Proportional plus Derivative (PD) control has been used widely to calculate the required forces to drive physically-based character animation. This approach requires the measurement of the state error or the difference ...

  • XML3D Physics: Declarative Physics Simulation for the Web 

    Sons, Kristian; Slusallek, Philipp (The Eurographics Association, 2011)
    As interactive 3D graphics has become an integral part of modern Web browsers via the low-level WebGL API [Khr11], it now becomes apparent that higher-level declarative approaches integrated with HTML5 are needed in order ...

  • Precomputed Shape Database for Real-Time Physically-Based Simulation 

    Glondu, Loeiz; Legouis, Benoit; Marchal, Maud; Dumont, Georges (The Eurographics Association, 2011)
    Adding dynamically physical properties to virtual objects can not generally be handled in real-time during a simulation. In this paper, we propose a method for handling the real-time physical simulations of arbitrary objects ...

  • Adding Physics to Animated Characters with Oriented Particles 

    Müller, Matthias; Chentanez, Nuttapong (The Eurographics Association, 2011)
    We present a method to enhance the realism of animated characters by adding physically based secondary motion to deformable parts such as cloth, skin or hair. To this end, we extend the oriented particles approach to ...

  • Towards Symmetry Axis based Markerless Motion Capture 

    Hartmann, Philip; Kahn, Svenja; Bockholt, Ulrich; Kuijper, Arjan (The Eurographics Association, 2011)
    A natural interaction with virtual environments is one of the key issues for the usability of Virtual Reality applications. Device-free, intuitive interactions with the virtual world can be achieved by capturing the movements ...

  • A Study On Perceptual Similarity of Human Motions 

    Krüger, Björn; Baumann, Jan; Abdallah, Mohammad; Weber, Andreas (The Eurographics Association, 2011)
    We perform a user study involving different classes of pre-recorded human motions displayed in abstract form either as stick figures or as point lights. Collecting data on more than 1000 user votes of various triples of ...

  • Interactive High-Resolution Boundary Surfaces for Deformable Bodies with Changing Topology 

    Wu, Jun; Dick, Christian; Westermann, Rüdiger (The Eurographics Association, 2011)
    Recent work has demonstrated that composite finite-elements provide an effective means for physically based modeling of deformable bodies. In this paper we present a number of highly effective improvements of previous work ...

  • SPH Based Shallow Water Simulation 

    Solenthaler, Barbara; Bucher, Peter; Chentanez, Nuttapong; Müller, Matthias; Gross, Markus (The Eurographics Association, 2011)
    We present an efficient method that uses particles to solve the 2D shallow water equations. These equations describe the dynamics of a body of water represented by a height field. Instead of storing the surface heights ...

  • Time Adaptive Approximate SPH 

    Goswami, Prashant; Pajarola, Renato (The Eurographics Association, 2011)
    In this paper, we present two different techniques to accelerate and approximate particle-based fluid simulations. The first technique identifies and employs larger time steps than dictated by the CFL condition. The second ...

  • Simulating Inextensible Cloth Using Locking-free Triangle Meshes 

    Bender, Jan; Diziol, Raphael; Bayer, Daniel (The Eurographics Association, 2011)
    This paper presents an effcient method for the dynamic simulation of inextensible cloth. The triangle mesh for our cloth model is simulated using an impulse-based approach which is able to solve hard constraints. Using ...
