    • Rendering Method for Flat Origami 

      Mitani, Jun (The Eurographics Association, 2008)
      In flat Origami (Origami which is folded flat), some cases exist that have a closed-loop in the overlap order of faces after they are folded. It is difficult to display this shape correctly on the screen when Origami is ...
    • Knitty: 3D Modeling of Knitted Animals with a Production Assistant Interface 

      Igarashi, Yuki; Igarashi, Takeo; Suzuki, Hiromasa (The Eurographics Association, 2008)
      Knitty is an interactive design system for creating knitted animals. The user designs a 3D surface model using a sketching interface. The system automatically generates a knitting pattern and then visualizes the shape of ...

      This paper presents experimental results of a mobile mixed reality interface designed for geovisualization of 3D realistic urban environments which allows dynamic switching between three visualization domains: a virtual ...
    • Mining Motifs from Human Motion 

      Meng, Jingjing; Yuan, Junsong; Hans, Mat; Wu, Ying (The Eurographics Association, 2008)
      Mining frequently occurring temporal motion patterns (motion motifs) is important for understanding, organizing and retrieving motion data. However, without any a priori knowledge of the motifs, such as their lengths, ...
    • Physically-Based Interactive Sand Simulation 

      Pla-Castells, Marta; García-Fernandez, Ignacio; Martinez-Dura, Rafael J. (The Eurographics Association, 2008)
      The interactive simulation of 3D terrains has been approached from several perspectives. Due to the complexity of the system involved, most of the models proposed focus on a visually realistic animation of the scene, rather ...
    • Microquad Soft Shadow Mapping Revisited 

      Schwarz, Michael; Stamminger, Marc (The Eurographics Association, 2008)
      Recently, real-time soft shadow research saw many important contributions from the class of soft shadow mapping algorithms, where approximate occluder geometry is reconstructed from a shadow map and backprojected onto the ...
    • Removing Artifacts Due To Frequency-Domain Processing of Light-Fields 

      Intwala, Chintan; Georgeiv, Todor (The Eurographics Association, 2008)
      In previous works, light-field capture has been analyzed in spatio-angular representation. A light-field camera samples the optical signal within a single photograph by multiplexing the 4D radiance onto the physical 2D ...
    • A Novel Approach to Support Quality of Experience in Remote Visualization on Mobile Devices 

      Paravati, Gianluca; Sanna, Andrea; Lamberti, Fabrizio; Ciminiera, Luigi (The Eurographics Association, 2008)
      This paper proposes a novel approach to support Quality of Experience (QoE) in remote visualization on mobile devices. Image resolution, frame rate, compression ratio, color depth, and device throughput are simultaneously ...
    • Shadowed Relighting of Dynamic Geometry with 1D BRDFs 

      Nowrouzezahrai, Derek; Kalogerakis, Evangelos; Simari, Patricio; Fiume, Eugene (The Eurographics Association, 2008)
      We present a method for synthesizing the dynamic self-occlusion of an articulating character in real-time (> 170Hz) while incorporating reflection effects from 1D BRDFs under dynamic lighting and view conditions. We ...
    • Measuring and Enhancing the Legibility of GPU-rendered Text 

      Tycowicz, Christoph von; Loviscach, Joern (The Eurographics Association, 2008)
      Whereas the rendering of tiny typefaces in 2D applications has been perfected over decades, the legibility of text in 3D visualizations has rarely been addressed. This affects road signs, meters, screens, and books in ...
    • Laziness is a Virtue: Motion Stitching Using Effort Minimization 

      Li, Lei; McCann, James; Faloutsos, Christos; Pollard, Nancy (The Eurographics Association, 2008)
      Given two motion-capture sequences that are to be stitched together, how can we assess the goodness of the stitching? The straightforward solution, Euclidean distance, permits counter-intuitive results because it ignores ...
    • Virtual Hair Handle: A Model for Haptic Hairstyling 

      Bonanni, Ugo; Kmoch, Petr (The Eurographics Association, 2008)
      The process of styling virtual hair is a tedious task for 3D artists, who would significantly profit from more natural and intuitive ways of creating virtual hairstyles - such as, for example, the possibility to simply ...
    • Efficient Soft Tissue Modelling Using Charged Particle Control Points 

      Buckley, Oliver; John, Nigel W. (The Eurographics Association, 2008)
      As the performance levels of personal computers increases so does the desire for more realistic and immersive software and simulation. An area where this is particularly the case is that of medical training simulation, ...
    • Contact Skinning 

      Duriez, Christian; Courtecuisse, Hadrien; Alcalde, Juan-Pablo de la Plata; Bensoussan, Pierre-Jean (The Eurographics Association, 2008)
      In this paper, we propose a new approach to model interactions through a skinning method. Skinning is a frequently used technique to animate a mesh based on skeleton motion. In the case of a hand motion sequence used to ...
