    • 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 ...

    • 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 ...

    • 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 ...

    • Volumetric Normal Mapping in Rendering of Multivariate Volume Data 

      Seipel, Stefan (The Eurographics Association, 2007)
      The work presented in this paper introduces volumetric normal maps for producing visual structure in direct volume rendering (DVR) of 3D data for the purpose of visualizing multiple attributes in a 3D volume. We use ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Stabilized Noise 

      Yoon, Jong-Chul; Lee, In-Kwon (The Eurographics Association, 2007)
      Perlin noise is generated by interpolation of a pre-defined random number table. However since the random number table is generated without considering the ideal properties of noise for computer graphics, the resulting ...

    • 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 ...

    • View-based Shape Similarity using Mutual Information Spheres 

      García, Francisco González; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2007)
      We present a new method for computing the shape similarity between 3D polygonal models using an informationtheoretic viewpoint selection framework. Given a 3D model, a sphere of viewpoints surrounding this model is used ...

    • Shape Analysis for Augmented Topological Shape Descriptor 

      Symonova, Olga; Amicis, Raffaele De (The Eurographics Association, 2007)
      In this work we propose a scheme for analysis of the shape of a 3D model.We use Extended Reeb Graph to describe the topological structure of the model which we further enrich with extracted geometrical features. The nodes ...

    • Reeb Chart Unfolding Based 3D Shape Signatures 

      Tierny, Julien; Vandeborre, Jean-Philippe; Daoudi, Mohamed (The Eurographics Association, 2007)
      This paper presents a novel surface parameterization based technique that addresses the pose insensitive shape signature problem for surface models of arbitrary genus. It is based on the key idea that two surface models ...

    • 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 ...

    • A Unified Interpolatory and Approximation sqrt-3 Subdivision Scheme 

      Lin, Shujin; Luo, Xiaonan (The Eurographics Association, 2007)
      We have found that there is a relationship between the cubic B-spline and four-point curve subdivision method. In the paper it is used to deduce interpolatory subdivision schemes from cubic B-spline based approximation ...

    • Report of the CGE 06 Computer Graphics Education Workshop, Vienna, Austria, September 9, 2006 

      Bourdin, Jean-Jacques; Cunningham, Steve; Fairn, Marta; Hansmann, Werner (The Eurographics Association, 2007)
      In order to include computer graphics in European university programme programmes in computer science, the computer graphics curriculum must be organised along lines that satisfy the Bologna requirements for cross ...

      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 ...
