  • Feature-Guided Dynamic Texture Synthesis on Continuous Flows 

    Narain, Rahul; Kwatra, Vivek; Lee, Huai-Ping; Kim, Theodore; Carlson, Mark; Lin, Ming C. (The Eurographics Association, 2007)
    We present a technique for synthesizing spatially and temporally varying textures on continuous flows using image or video input, guided by the physical characteristics of the fluid stream itself. This approach enables the ...
  • Interactive Smooth and Curved Shell Mapping 

    Jeschke, Stefan; Mantler, Stephan; Wimmer, Michael (The Eurographics Association, 2007)
    Shell mapping is a technique to represent three-dimensional surface details. This is achieved by extruding the triangles of an existing mesh along their normals, and mapping a 3D function (e.g., a 3D texture) into the ...
  • Compressed Random-Access Trees for Spatially Coherent Data 

    Lefebvre, Sylvain; Hoppe, Hugues (The Eurographics Association, 2007)
    Adaptive multiresolution hierarchies are highly efficient at representing spatially coherent graphics data. We introduce a framework for compressing such adaptive hierarchies using a compact randomly-accessible tree ...
  • Using Photographs to Enhance Videos of a Static Scene 

    Bhat, Pravin; Zitnick, C. Lawrence; Snavely, Noah; Agarwala, Aseem; Agrawala, Maneesh; Cohen, Michael; Curless, Brian; Kang, Sing Bing (The Eurographics Association, 2007)
    We present a framework for automatically enhancing videos of a static scene using a few photographs of the same scene. For example, our system can transfer photographic qualities such as high resolution, high dynamic range ...
  • High Dynamic Range Image Hallucination 

    Wang, Lvdi; Wei, Li-Yi; Zhou, Kun; Guo, Baining; Shum, Heung-Yeung (The Eurographics Association, 2007)
    We introduce high dynamic range image hallucination for adding high dynamic range details to the over-exposed and under-exposed regions of a low dynamic range image. Our method is based on a simple assumption: there exist ...
  • Natural Image Colorization 

    Luan, Qing; Wen, Fang; Cohen-Or, Daniel; Liang, Lin; Xu, Ying-Qing; Shum, Heung-Yeung (The Eurographics Association, 2007)
    In this paper, we present an interactive system for users to easily colorize the natural images of complex scenes. In our system, colorization procedure is explicitly separated into two stages: Color labeling and Color ...
  • An Interactive Perceptual Rendering Pipeline using Contrast and Spatial Masking 

    Drettakis, George; Bonneel, Nicolas; Dachsbacher, Carsten; Lefebvre, Sylvain; Schwarz, Michael; Viaud-Delmon, Isabelle (The Eurographics Association, 2007)
    We present a new perceptual rendering pipeline which takes into account visual masking due to contrast and spatial frequency. Our framework predicts inter-object, scene-level masking caused by partial occlusion and shadows. ...
  • Incremental Instant Radiosity for Real-Time Indirect Illumination 

    Laine, Samuli; Saransaari, Hannu; Kontkanen, Janne; Lehtinen, Jaakko; Aila, Timo (The Eurographics Association, 2007)
    We present a method for rendering single-bounce indirect illumination in real time on currently available graphics hardware. The method is based on the instant radiosity algorithm, where virtual point lights (VPLs) are ...
  • Soft Shadows by Ray Tracing Multilayer Transparent Shadow Maps 

    Xie, Feng; Tabellion, Eric; Pearce, Andrew (The Eurographics Association, 2007)
    We present a method for high quality soft shadows for area lights in cinematic lighting. The method is an extension of traditional shadow maps, so it has the advantage of image based shadow methods; the algorithm s complexity ...
  • Photorealistic Image Rendering with Population Monte Carlo Energy Redistribution 

    Lai, Yu-Chi; Fan, Shao Hua; Chenney, Stephen; Dyer, Charcle (The Eurographics Association, 2007)
    This work presents a novel global illumination algorithm which concentrates computation on important light transport paths and automatically adjusts energy distributed area for each light transport path. We adapt statistical ...
  • Physically Based Real-Time Translucency for Leaves 

    Habel, Ralf; Kusternig, Alexander; Wimmer, Michael (The Eurographics Association, 2007)
    This paper presents a new shading model for real-time rendering of plant leaves that reproduces all important attributes of a leaf and allows for a large number of leaves to be shaded. In particular, we use a physically ...
  • Rendering Translucent Materials Using Photon Diffusion 

    Donner, Craig; Jensen, Henrik Wann (The Eurographics Association, 2007)
    We present a new algorithm for rendering translucent materials that combines photon tracing with diffusion. This combination makes it possible to efficiently render highly scattering translucent materials while accounting ...
  • Procedural Editing of Bidirectional Texture Functions 

    Mueller, Gero; Sarlette, Ralf; Klein, Reinhard (The Eurographics Association, 2007)
    Measured material representations like Bidirectional Texture Functions or Reflectance Fields offer very realistic appearance but the user is currently not capable of changing this appearance in an effective and intuitive ...
  • Rendering Discrete Random Media Using Precomputed Scattering Solutions 

    Moon, Jonathan T.; Walter, Bruce; Marschner, Stephen R. (The Eurographics Association, 2007)
    This paper addresses light transport through a discrete random medium, which we define as a volume filled with macroscopic scattering geometry generated by a random process. This formulation is more general than standard ...
  • Efficient Basis Decomposition for Scattered Reflectance Data 

    Weistroffer, R. Peter; Walcott, Kristen R.; Humphreys, Greg; Lawrence, Jason (The Eurographics Association, 2007)
    Recent progress in acquisition technology has increased the availability and quality of measured appearance data. Although representations based on dimensionality reduction provide the greatest fidelity to measured data, ...
  • Microfacet Models for Refraction through Rough Surfaces 

    Walter, Bruce; Marschner, Stephen R.; Li, Hongsong; Torrance, Kenneth E. (The Eurographics Association, 2007)
    Microfacet models have proven very successful for modeling light reflection from rough surfaces. In this paper we review microfacet theory and demonstrate how it can be extended to simulate transmission through rough ...

    Ma, Wan-Chun; Hawkins, Tim; Peers, Pieter; Chabert, Charles-Felix; Weiss, Malte; Debevec, Paul (The Eurographics Association, 2007)
    We estimate surface normal maps of an object from either its diffuse or specular reflectance using four spherical gradient illumination patterns. In contrast to traditional photometric stereo, the spherical patterns allow ...

    Garg, Kshitiz; Krishnan, Gurunandan G.; Nayar, Shree K. (The Eurographics Association, 2007)
    The splashing of a water drop is a fascinating phenomenon that results from a variety of complex interactions between the drop and the material it impacts. In general, the distribution of droplets of a splash depends on ...
