    • 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 ...
    • 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 ...

    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Object-Oriented Shader Design 

      Kuck, Roland (The Eurographics Association, 2007)
      We present an extremely lightweight object-oriented framework for writing shaders. It provides a way to invoke methods of objects from the shading language and to use references of objects as normal variables. Classes are ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
