    • An Accurate Implicit Field Representation for Meshes and Its Adapted Triangulation Algorithms 

      Fournier, Marc; Dischler, J. - M.; Bechmann, D. (The Eurographics Association, 2007)
      The classic implicit scalar field distance transform representation of a mesh is very useful to perform many mesh processing operations and to obtain better results than with other methods. In this paper we propose a new ...

    • Adaptive Abstraction of 3D scenes in Real-Time 

      Redmond, Niall; Dingliana, John (The Eurographics Association, 2007)
      We present an approach for creating abstracted renderings of 3D scenes in real-time. We create painterly renderings with edge detail using varying levels of abstraction dependent on regions of interest within a scene. Image ...

    • Analysis of the Pulmonary Vein Ostia using Cardiac 4DCT for Radiosurgical Ablation 

      Sumanaweera, Thilaka; Conti, Francois; Maguire, Patrick (The Eurographics Association, 2007)
      A software tool to analyze 4D cardiac CT data sets for planning radiosurgical ablations in the heart is presented. Volume rendering and data processing are performed using a GPU. The user visualizes the data from inside ...

    • Automated Combination of Real-Time Shader Programs 

      Trapp, Matthias; Döller, Jürgen (The Eurographics Association, 2007)
      This work proposes an approach for automatic and generic runtime-combination of high-level shader programs. Many of recently introduced real-time rendering techniques rely on such programs. The fact that only a single ...

    • Bridging Semantic Web and Digital Shapes 

      Papaleo, Laura; Floriani, Leila De; Hendler, Jim (The Eurographics Association, 2007)
      Since the volume of multimedia content available on the Web is continuously increasing, a clear need for advanced techniques capable of performing an effective retrieval and management of such data. In this context, in ...

    • Construction of Non-Blobby Surface from Particles 

      Harada, Takahiro; Koshizuka, Seiichi; Kawaguchi, Yoichiro (The Eurographics Association, 2007)
      This paper presents a method that can construct a surface with a thin region or sharp edges from particles. The surface is constructed in two stages. An implicit surface is generated by assigning a density distribution to ...

    • 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 ...

    • 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 ...

    • 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)
      We present a novel multi-step technique for imperceptible geometry and radiometry calibration of projectorcamera systems. Our approach can be used to display geometry and color corrected images on non-optimized surfaces ...

    • Improved Skeleton Computation of an Encoded Volume 

      Ayala, Dolors (The Eurographics Association, 2007)
      In this communication, we present an improvement of an existing thinning algorithm that computes a surface skeleton from a binary volume. The method makes an intensive use of Boolean operations and works on a special ...

    • Liquid Diffusion Model that Accounts for a Variety of Dyeing Parameters 

      Yuki, Morimoto; Tanaka, Masayuki; Tsuruno, Reiji; Tomimatsu, Kiyoshi (The Eurographics Association, 2007)
