    • An E-Learning Course on Scientific Visualization 

      Taras, Christiane; Rotard, Martin; Ertl, Thomas (The Eurographics Association, 2007)
      In this paper we present an e-learning course on scientific visualization. Based on over ten years of teaching experiences in this field, we have created a multimedia online course which we use as additional material for ...

    • EG 2007 Course on Populating Virtual Environments with Crowds 

      Thalmann, Daniel; O'Sullivan, Carol; Yersin, Barbara; Maïm, Jonathan; McDonnell, Rachel (The Eurographics Association, 2007)
      For many years, it was a challenge to produce realistic virtual crowds for special effects in movies. Now, there is a new challenge: the production of real-time autonomous Virtual Crowds. Real-time crowds are necessary for ...

    • Enforcing Scene Constraints in Single View Reconstruction 

      Lourakis, Manolis; Argyros, Antonis (The Eurographics Association, 2007)
      Three-dimensional reconstruction from a single view is an under-constrained process that relies critically upon the availability of prior knowledge about the imaged scene. This knowledge is assumed to be supplied by a user ...

    • Exact Computation of the Hausdorff Distance between Triangular Meshes 

      Straub, Raphael (The Eurographics Association, 2007)
      We present an algorithm that computes the exact Hausdorff distance between two arbitrary triangular meshes. Our method computes squared distances for each point on each triangle of one mesh to all relevant triangles of the ...

    • Exemplar-based Worn Edges 

      Brachmann, Christoph; Walther-Franks, Benjamin; JörnLoviscach, (The Eurographics Association, 2007)
      To counteract the sterile look of computer-generated worlds, we introduce a procedural model for worn edges that can be seen in buildings and stones: edges that have suffered minor damage at multiple points, resulting in ...

    • Extended Game Platform for Novice Programmers 

      Rankin, Yolanda; Lechner, Thomas (The Eurographics Association, 2007)
      In an attempt to recruit and retain computer science majors, game design courses have become increasingly popular in academia. Game design encompasses multiple stages of product development, takes an average of two or more ...

    • Fast GPU-based Visibility Computation for Natural Illumination of Volume Data Sets 

      Ritschel, Tobias (The Eurographics Association, 2007)
      Pre-computed radiance transfer (PRT) has been used to render volumetric data under distant low-frequency illumination at real-time rates, including natural illumination, soft shadows, attenuation from semi-transparent ...

    • Fast Hierarchical 3D Distance Transforms on the GPU 

      Cuntz, Nicolas; Kolb, Andreas (The Eurographics Association, 2007)
      This paper describes a fast approximate approach for the GPU-based computation of 3D Euclidean distance transforms (DT), i.e. distance fields with associated vector information to the closest object point. Our hierarchical ...

    • Fast Hierarchical Methods to Detect Collisions between Deformable Objects: A Comparison 

      Madera, Francisco; Day, A. M.; Laycock, S. D. (The Eurographics Association, 2007)
      The time complexity of a collision detection algorithm can be reduced to logarithmic in the number of tests performed when the objects are decomposed into a Bounding Volume (BV) tree hierarchy. It is well known that the ...

    • Flatland: A Tool for Transforming Historical Sites into Archival Drawings 

      Srisinroongruang, Rattasak; Sinzinger, Eric; Hill, Glenn (The Eurographics Association, 2007)
      Detailed documentation of historical sites is important for archaeological discovery and cultural preservation. The traditional method of documentation is to hand sketch 2D drawings of the region. Laser range finders can ...

    • Haptic Simulation, Perception and Manipulation of Deformable Objects 

      Magnenat-Thalmann, Nadia; Volino, Pascal; Bonanni, Ugo; Summers, Ian R.; Brady, A. C.; Qu, J.; Allerkamp, D.; Fontana, M.; Tarri, F.; Salsedo, F.; Bergamasco, Massimo (The Eurographics Association, 2007)
      This tutorial addresses haptic simulation, perception and manipulation of complex deformable objects in virtual environments (VE). We first introduce HAPTEX, a research project dealing with haptic simulation and perception ...

    • High Speed Skin Color Detection and Localization on a GPU 

      Seshadrinathan, Manoj; Dempski, Kelly (The Eurographics Association, 2007)
      In this paper, we present a simple yet novel method for high speed skin color detection and localization on images and video using the Graphics Processing Unit (GPU) and common graphics programming techniques. Our approach ...

    • Imperceptible Calibration for Radiometric Compensation 

      Zollmann, Stefanie; Bimber, Oliver (The Eurographics Association, 2007)
