    • A Shape Descriptor for 3D Objects Based on Rotational Symmetry 

      Martinek, M.; Grosso, R.; Greiner, G. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      The ability to extract spatial features from 3D objects is essential for applications such as shape matching and object classification. However, designing an effective feature vector which is invariant with respect to ...

    • A Smoke Visualization Model for Capturing Surface-Like Features 

      Park, Jinho; Seol, Yeongho; Cordier, Frederic; Noh, Junyong (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Incense, candle smoke and cigarette smoke often exhibit smoke flows with a surface-like appearance. Although delving into well-known computational fluid dynamics may provide a solution to create such an appearance, we ...

    • A Survey of Procedural Noise Functions 

      Lagae, A.; Lefebvre, S.; Cook, R.; DeRose, T.; Drettakis, G.; Ebert, D.S.; Lewis, J.P.; Perlin, K.; Zwicker, M. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Procedural noise functions are widely used in computer graphics, from off-line rendering in movie production to interactive video games. The ability to add complex and intricate details at low memory and authoring cost is ...

    • Teaching Quaternions is not Complex 

      McDonald, J. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Quaternions are used in many fields of science and computing, but teaching them remains challenging. Students can have a great deal of trouble understanding essentially what quaternions are and how they can represent ...

    • Tone Mapping Operators on Small Screen Devices: An Evaluation Study 

      Urbano, C.; Magalhaes, L.; Moura, J.; Bessa, M.; Marcos, A.; Chalmers, A. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In the last decade, an increasing number of techniques have been developed to reproduce high dynamic range imagery on traditional displays. These techniques, known as Tone Mapping Operators (TMOs), have been compared and ...

    • Transparent and Specular Object Reconstruction 

      Ihrke, Ivo; Kutulakos, Kiriakos N.; Lensch, Hendrik P. A.; Magnor, Marcus; Heidrich, Wolfgang (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This state of the art report covers reconstruction methods for transparent and specular objects or phenomena. While the 3D acquisition of opaque surfaces with Lambertian reflectance is a well-studied problem, transparent, ...

    • Virtual Video Camera: Image-Based Viewpoint Navigation Through Space and Time 

      Lipski, C.; Linz, C.; Berger, K.; Sellent, A.; Magnor, M. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present an image-based rendering system to viewpoint-navigate through space and time of complex real-world, dynamic scenes. Our approach accepts unsynchronized, uncalibrated multivideo footage as input. Inexpensive, ...

    • Visualization of Large-Scale Urban Models through Multi-Level Relief Impostors 

      Andujar, C.; Brunet, P.; Chica, A.; Navazo, I. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper, we present an efficient approach for the interactive rendering of large-scale urban models, which can be integrated seamlessly with virtual globe applications. Our scheme fills the gap between standard ...
