  • A Hybrid Monte Carlo Method for Accurate and Efficient Subsurface Scattering 

    Li, Hongsong; Pellacini, Fabio; Torrance, Kenneth E. (The Eurographics Association, 2005)
    Subsurface scattering is a fundamental aspect of surface appearance responsible for the characteristic look of many materials. Monte Carlo path tracing techniques can be employed with high accuracy to simulate the scattering ...
  • Real-Time Multiple Scattering in Participating Media with Illumination Networks 

    Szirmay-Kalos, László; Sbert, Mateu; Ummenhoffer, Tamás (The Eurographics Association, 2005)
    This paper proposes a real-time method to compute multiple scattering in non-homogeneous participating media having general phase functions. The volume represented by a particle system is supposed to be static, but the ...
  • Non-linear Volume Photon Mapping 

    Gutierrez, Diego; Munoz, Adolfo; Anson, Oscar; Seron, Francisco J. (The Eurographics Association, 2005)
    This paper describes a novel extension of the photon mapping algorithm, capable of handling both volume multiple inelastic scattering and curved light paths simultaneously. The extension is based on the Full Radiative ...
  • Adaptive Frameless Rendering 

    Dayal, Abhinav; Woolley, Cliff; Watson, Benjamin; Luebke, David (The Eurographics Association, 2005)
    We propose an adaptive form of frameless rendering with the potential to dramatically increase rendering speed over conventional interactive rendering approaches. Without the rigid sampling patterns of framed renderers, ...
  • Reflectance Sharing: Image-based Rendering from a Sparse Set of Images 

    Zickler, Todd; Enrique, Sebastian; Ramamoorthi, Ravi; Belhumeur, Peter (The Eurographics Association, 2005)
    When the shape of an object is known, its appearance is determined by the spatially-varying reflectance function defined on its surface. Image-based rendering methods that use geometry seek to estimate this function from ...
  • Real Illumination from Virtual Environments 

    Ghosh, Abhijeet; Trentacoste, Matthew; Seetzen, Helge; Heidrich, Wolfgang (The Eurographics Association, 2005)
    We introduce a method for actively controlling the illumination in a room so that it is consistent with a virtual world. In combination with a high dynamic range display, the system produces both uniform and directional ...
  • Perceptually Based Tone Mapping of High Dynamic Range Image Streams 

    Irawan, Piti; Ferwerda, James A.; Marschner, Stephen R. (The Eurographics Association, 2005)
    This paper presents a new perceptually based tone mapping operator that represents scene visibility under timevarying, high dynamic range conditions. The operator is based on a new generalized threshold model that extends ...
  • Fast Exact From-Region Visibility in Urban Scenes 

    Bittner, Jiri; Wonka, Peter; Wimmer, Michael (The Eurographics Association, 2005)
    We present a fast exact from-region visibility algorithm for 2.5D urban scenes. The algorithm uses a subdivision of line space for identifying visibility interactions in a 2D footprint of the scene. Visibility in the ...
  • A Low Dimensional Framework for Exact Polygon-to-Polygon Occlusion Queries 

    Haumont, Denis; Makinen, Otso; Nirenstein, Shaun (The Eurographics Association, 2005)
    Despite the importance of from-region visibility computation in computer graphics, efficient analytic methods are still lacking in the general 3D case. Recently, different algorithms have appeared that maintain occlusion ...
  • Colorization by Example 

    Irony, Revital; Cohen-Or, Daniel; Lischinski, Dani (The Eurographics Association, 2005)
    We present a new method for colorizing grayscale images by transferring color from a segmented example image. Rather than relying on a series of independent pixel-level decisions, we develop a new strategy that attempts ...
  • Stippling and Silhouettes Rendering in Geometry-Image Space 

    Yuan, Xiaoru; Nguyen, Minh X.; Zhang, Nan; Chen, Baoquan (The Eurographics Association, 2005)
    We present a novel non-photorealistic rendering method that performs all operations in a geometry-image domain. We first apply global conformal parameterization to the input geometry model and generate corresponding geometry ...
  • Geometric Clustering for Line Drawing Simplification 

    Barla, Pascal; Thollot, Joelle; Sillion, François X. (The Eurographics Association, 2005)
    We present a new approach to the simplification of line drawings, in which a smaller set of lines is created to represent the geometry of the original lines. An important feature of our method is that it maintains the ...
  • Inferring Reflectance Functions from Wavelet Noise 

    Peers, Pieter; Dutré, Philip (The Eurographics Association, 2005)
    This paper presents a novel method for acquiring a wavelet representation of the reflectance field of real objects. Key to our method is the use of wavelet noise illumination to infer a reflectance function for each pixel. ...
  • Table-top Computed Lighting for Practical Digital Photography 

    Mohan, Ankit; Tumblin, Jack; Bodenheimer, Bobby; Grimm, Cindy; Bailey, Reynold (The Eurographics Association, 2005)
    We apply simplified image-based lighting methods to reduce the equipment, cost, time, and specialized skills required for high-quality photographic lighting of desktop-sized static objects such as museum artifacts. We place ...
  • Bayesian Relighting 

    Fuchs, Martin; Blanz, Volker; Seidel, Hans-Peter (The Eurographics Association, 2005)
    We present a simple method for relighting real objects viewed from a fixed camera position. Instead of setting up a calibrated measurement device, such as a light stage, we manually sweep a spotlight over the walls of a ...
  • Bidirectional Importance Sampling for Direct Illumination 

    Burke, David; Ghosh, Abhijeet; Heidrich, Wolfgang (The Eurographics Association, 2005)
    Image-based representations for illumination can capture complex real-world lighting that is difficult to represent in other forms. Current importance sampling strategies for image-based illumination have difficulties in ...
  • Metropolis Photon Sampling with Optional User Guidance 

    Fan, Shaohua; Chenney, Stephen; Lai, Yu-chi (The Eurographics Association, 2005)
    We present Metropolis Photon Sampling (MPS), a visual importance-driven algorithm for populating photon maps. Photon Mapping and other particle tracing algorithms fail if the photons are poorly distributed. Our approach ...
  • Importance Resampling for Global Illumination 

    Talbot, Justin; Cline, David; Egbert, Parris (The Eurographics Association, 2005)
    This paper develops importance resampling into a variance reduction technique for Monte Carlo integration. Importance resampling is a sample generation technique that can be used to generate more equally weighted samples ...
  • Experimental Analysis of BRDF Models 

    Ngan, Addy; Durand, Frédo; Matusik, Wojciech (The Eurographics Association, 2005)
    The Bidirectional Reflectance Distribution Function (BRDF) describes the appearance of a material by its interaction with light at a surface point. A variety of analytical models have been proposed to represent BRDFs. ...
  • Multiresolution Reflectance Filtering 

    Tan, Ping; Lin, Stephen; Quan, Long; Guo, Baining; Shum, Heung-Yeung (The Eurographics Association, 2005)
    Physically-based reflectance models typically represent light scattering as a function of surface geometry at the pixel level. With changes in viewing resolution, the geometry imaged within a pixel can undergo significant ...
