  • Generating Pointillism Paintings Based on Seurat's Color Composition 

    Wu, Yi-Chian; Tsai, Yu-Ting; Lin, Wen-Chieh; Li, Wen-Hsin (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    This paper presents a novel example-based stippling technique that employs a simple and intuitive concept to convert a color image into a pointillism painting. Our method relies on analyzing and imitating the color ...
  • Optimizing Disparity for Motion in Depth 

    Kellnhofer, Petr; Ritschel, Tobias; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Beyond the careful design of stereo acquisition equipment and rendering algorithms, disparity post-processing has recently received much attention, where one of the key tasks is to compress the originally large disparity ...
  • Interactive Lighting Design with Hierarchical Light Representation 

    Lin, Wen-Chieh; Huang, Tsung-Shian; Ho, Tan-Chi; Chen, Yueh-Tse; Chuang, Jung-Hong (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Lighting design plays a crucial role in indoor lighting design, computer cinematograph and many other applications. Computer-assisted lighting design aims to find a lighting configuration that best approximates the ...
  • Factorized Point Based Global Illumination 

    Wang, Beibei; Huang, Jing; Buchholz, Bert; Meng, Xiangxu; Boubekeur, Tamy (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    The Point-Based Global Illumination (PBGI) algorithm is composed of two major steps: a caching step and a multiview rasterization step. At caching time, a dense point-sampling of the scene is shaded and organized in a ...
  • Sorted Deferred Shading for Production Path Tracing 

    Eisenacher, Christian; Nichols, Gregory; Selle, Andrew; Burley, Brent (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Ray-traced global illumination (GI) is becoming widespread in production rendering but incoherent secondary ray traversal limits practical rendering to scenes that fit in memory. Incoherent shading also leads to intractable ...
  • Exponential Soft Shadow Mapping 

    Shen, Li; Feng, Jieqing; Yang, Baoguang (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    In this paper we present an image-based algorithm to render visually plausible anti-aliased soft shadows in real time. Our technique employs a new shadow pre-filtering method based on an extended exponential shadow mapping ...
  • Temporally Coherent Adaptive Sampling for Imperfect Shadow Maps 

    Barák, Tomas; Bittner, Jiri; Havran, Vlastimil (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We propose a new adaptive algorithm for determining virtual point lights (VPL) in the scope of real-time instant radiosity methods, which use a limited number of VPLs. The proposed method is based on Metropolis-Hastings ...
  • Line-Sweep Ambient Obscurance 

    Timonen, Ville (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Screen-space ambient occlusion and obscurance have become established methods for rendering global illumi- nation effects in real-time applications. While they have seen a steady line of refinements, their computational ...
  • A Shape-Aware Model for Discrete Texture Synthesis 

    Landes, Pierre-Edouard; Galerne, Bruno; Hurtut, Thomas (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We present a novel shape-aware method for synthesizing 2D and 3D discrete element textures consisting of collections of distinct vector graphics objects. Extending the long-proven point process framework, we propose a shape ...
  • A Topological Approach to Voxelization 

    Laine, Samuli (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We present a novel approach to voxelization, based on intersecting the input primitives against intersection targets in the voxel grid. Instead of relying on geometric proximity measures, our approach is topological in ...
  • An Area-Preserving Parametrization for Spherical Rectangles 

    Ureña, Carlos; Fajardo, Marcos; King, Alan (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We present an area-preserving parametrization for spherical rectangles which is an analytical function with domain in the unit rectangle [0;1]2 and range in a region included in the unit-radius sphere. The parametrization ...
  • Spherical Visibility Sampling 

    Eikel, Benjamin; Jähn, Claudius; Fischer, Matthias; Heide, Friedhelm Meyer auf der (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Many 3D scenes (e.g. generated from CAD data) are composed of a multitude of objects that are nested in each other. A showroom, for instance, may contain multiple cars and every car has a gearbox with many gearwheels located ...
  • Photon Beam Diffusion: A Hybrid Monte Carlo Method for Subsurface Scattering 

    Habel, Ralf; Christensen, Per H.; Jarosz, Wojciech (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We present photon beam diffusion, an efficient numerical method for accurately rendering translucent materials. Our approach interprets incident light as a continuous beam of photons inside the material. Numerically ...
  • Probabilistic Visibility Evaluation for Direct Illumination 

    Billen, Niels; Engelen, Björn; Lagae, Ares; Dutré, Philip (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    The efficient evaluation of visibility in a three-dimensional scene is a longstanding problem in computer graphics. Visibility evaluations come in many different forms: figuring out what object is visible in a pixel; ...
  • Automatic Cinemagraph Portraits 

    Bai, Jiamin; Agarwala, Aseem; Agrawala, Maneesh; Ramamoorthi, Ravi (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Cinemagraphs are a popular new type of visual media that lie in-between photos and video; some parts of the frame are animated and loop seamlessly, while other parts of the frame remain completely still. Cinemagraphs are ...
  • Computational Simulation of Alternative Photographic Processes 

    Echevarria, Jose I.; Wilensky, Gregg; Krishnaswamy, Aravind; Kim, Byungmoon; Gutierrez, Diego (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We present a novel computational framework for physically and chemically-based simulations of analog alternative photographic processes. In the real world, these processes allow the creation of very personal and unique ...
  • Practical Real-Time Lens-Flare Rendering 

    Lee, Sungkil; Eisemann, Elmar (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We present a practical real-time approach for rendering lens-flare effects. While previous work employed costly ray tracing or complex polynomial expressions, we present a coarser, but also significantly faster solution. ...
