    • Perceptually Based Afterimage Synthesis 

      Mikamo, Michihiro; Slomp, Marcos; Raytchev, Bisser; Tamaki, Toru; Kaneda, Kazufumi (The Eurographics Association, 2012)
      Afterimages comprise a common, recurring perceptual phenomenon experienced in a daily-basis. Afterimages are best realized when staring at some high intensity light source (i.e., a light bulb) and then shifting the ocular ...

    • Robust Outlier Removal from Point Clouds Acquired with Structured Light 

      Köhler, Johannes; Nöll, Tobias; Reis, Gerd; Stricker, Didier (The Eurographics Association, 2012)
      We present a method for automatic, robust identification of outliers in point clouds acquired with structured light. In contrast to most state of the art methods, we consider available 2D information instead of operating ...

    • Growing Cell Structures Learning a Progressive Mesh During Surface Reconstruction - A Top-Down Approach 

      Vierjahn, Tom; Lorenz, Guido; Mostafawy, Sina; Hinrichs, Klaus (The Eurographics Association, 2012)
      Growing Cell Structures (GCS) have been proven to be suitable for surface reconstruction from unstructured point clouds. The reconstructed triangle mesh can be represented compactly as a progressive mesh with integrated ...

    • Hybrid CPU/GPU KD-Tree Construction for Versatile Ray Tracing 

      Roccia, Jean-Patrick; Paulin, Mathias; Coustet, Christophe (The Eurographics Association, 2012)
      We propose an hybrid CPU-GPU ray-tracing implementation based on an optimal Kd-Tree as acceleration structure. The construction and traversal of this KD-tree takes benefit from both the CPU and the GPU to achieve ...

    • Forward+: Bringing Deferred Lighting to the Next Level 

      Harada, Takahiro; McKee, Jay; Yang, Jason C. (The Eurographics Association, 2012)
      This paper presents Forward+, a method of rendering many lights by culling and storing only lights that contribute to the pixel. Forward+ is an extension to traditional forward rendering. Light culling, implemented using ...

    • Reflective Shadow Map Clustering for Real-Time Global Illumination 

      Prutkin, Roman; Kaplanyan, Anton; Dachsbacher, Carsten (The Eurographics Association, 2012)
      We present a method for real-time clustering of VPLs obtained from Reflective Shadow Maps (RSM). The clusters are treated as area light sources and used to approximate indirect illumination. The spatial extent of a cluster ...

    • Skeleton Based Importance Sampling for Path Tracing 

      Biri, Venceslas; Chaussard, John (The Eurographics Association, 2012)
      When working with large and complex scenes, situations arise where light flux takes complex paths to reach the observer. In such cases, traditional stochastic algorithms, like ray tracing algorithms, will have difficulties ...

    • Consistent Media Model for Real-Time Scene Rendering 

      Belhadj, Farès; Suarez, Jordane; Boyer, Vincent (The Eurographics Association, 2012)
      We present a consistent model for artistic media reproduction in 3D scene renderings and animations. Artistic media reproduction can be defined as a media model (such as brush, pencil, ink) and a support (such as canvas ...

    • Realtime 3D Sensor Based Air Flow Reconstruction 

      Dyck, Michiel Van; Peremans, Herbert (The Eurographics Association, 2012)
      Based on state-of-the art bio-inspired air flow sensors it becomes possible to capture air flow velocity and direction at multiple locations at the same time instance. These sensor values can be used in a simulation ...

    • Joint Interactive Visualization of 3D Models and Pictures in Walkable Scenes 

      Brivio, Paolo; Tarini, Marco; Cignoni, Paolo; Scopigno, Roberto (The Eurographics Association, 2012)
      The 3D digitalization of buildings, urban scenes, and the like is now a mature technology. Highly complex, densely sampled, reasonably accurate 3D models can be obtained by range-scanners and even image-based reconstruction ...

    • Multiview-Consistent Color Sampling for Alpha Matting 

      Kettern, Markus; Eisert, Peter (The Eurographics Association, 2012)
      We propose a method for incorporating multiview information into color sampling methodologies for alpha matting. We extend the typical trimap input for matting algorithms to 3D space, enabling the association of stripes ...

    • GPU Texture Level of Abstraction in 3D Scenes 

      Suarez, Jordane; Belhadj, Farès; Boyer, Vincent (The Eurographics Association, 2012)
      We present a method to dynamically control the texture level of abstraction in 3D scene. Level of abstraction consists in visualizing the necessary and sufficient information in an image. Texture generation is generally ...

    • Combining Structure from Motion and Photometric Stereo: A Piecewise Formulation 

      Sabzevari, Reza; Bue, Alessio Del; Murino, Vittorio (The Eurographics Association, 2012)
      This paper introduces a novel piecewise formulation for Photometric Stereo on static scenes exploiting a set of multiple view constraints on the surface. Such constraints will help to recover geometrical properties of the ...

    • Multi-user Immersive 3D Reconstruction Environment 

      Sedlacek, David; Travnicek, Zdenek; Zara, Jiri (The Eurographics Association, 2012)
      A tool for user driven 3D reconstruction is presented in this poster together with ideas of tool extension for a work in immersive environment with multi-user editing possibility. The main purpose of the tool is cultural ...

    • Minimising Longest Edge for Closed Surface Construction from Unorganised 3D Point Sets 

      Ohrhallinger, Stefan; Mudur, Sudhir (The Eurographics Association, 2012)
      Given an unorganised 3D point set with just coordinate data, we formulate the problem of closed surface construction as one requiring minimisation of longest edge in triangles, a criterion derivable from Gestalt laws for ...

    • Meshless Statistical Occlusion Computation 

      Fouquet, François; Farrugia, Jean-Philippe; Iehl, Jean-Claude; Dupuy, Jonathan (The Eurographics Association, 2012)
