    • Erosion Based Visibility Preprocessing 

      Décoret, Xavier; Debunne, Gilles; Sillion, François (The Eurographics Association, 2003)
      This paper presents a novel method for computing visibility in 2.5D environments based on a novel theoretical result: the visibility from a region can be conservatively estimated by computing the visibility from a point ...

    • Detail to Attention: Exploiting Visual Tasks for Selective Rendering 

      Cater, K.; Chalmers, A.; Ward, G. (The Eurographics Association, 2003)
      The perceived quality of computer graphics imagery depends on the accuracy of the rendered frames, as well as the capabilities of the human visual system. Fully detailed, high fidelity frames still take many minutes even ...

    • Refinement Criteria Based on f-Divergences 

      Rigau, Jaume; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2003)
      In several domains a refinement criterion is often needed to decide whether to go on or to stop sampling a signal. When the sampled values are homogeneous enough, we assume that they represent the signal fairly well and ...

    • Recovering 3-D Shape and Reflectance From a Small Number of Photographs 

      Georghiades, Athinodoros S. (The Eurographics Association, 2003)
      There are computer graphics applications for which the shape and reflectance of complex objects, such as faces, cannot be obtained using specialized equipment due to cost and practical considerations. We present an imagebased ...

    • Efficient Isotropic BRDF Measurement 

      Matusik, Wojciech; Pfister, Hanspeter; Brand, Matthew; McMillan, Leonard (The Eurographics Association, 2003)
      In this paper we present novel reflectance measurement procedures that require fewer total measurements than standard uniform sampling approaches. First, we acquire densely sampled reflectance data for a large collection ...

    • Optimizing Color Matching in a Lighting Reproduction System for Complex Subject and Illuminant Spectra 

      Wenger, A.; Hawkins, T.; Debevec, P. (The Eurographics Association, 2003)
      This paper presents a technique for improving color matching results in an LED-based lighting reproduction system for complex light source spectra. In our technique, we use measurements of the spectral response curve of ...

    • Rapid Shadow Generation in Real-World Lighting Environments 

      Gibson, Simon; Cook, Jon; Howard, Toby; Hubbold, Roger (The Eurographics Association, 2003)
      We propose a new algorithm that uses consumer-level graphics hardware to render shadows cast by synthetic objects and a real lighting environment. This has immediate benefit for interactive Augmented Reality applications, ...

    • Rendering Fake Soft Shadows with Smoothies 

      Chan, Eric; Durand, Fredo (The Eurographics Association, 2003)
      We present a new method for real-time rendering of shadows in dynamic scenes. Our approach builds on the shadow map algorithm by attaching geometric primitives that we call "smoothies" to the objects' silhouettes. The ...

    • Penumbra Maps: Approximate Soft Shadows in Real-Time 

      Wyman, Chris; Hansen, Charles (The Eurographics Association, 2003)
      Generating soft shadows quickly is difficult. Few techniques have enough flexibility to interactively render soft shadows in scenes with arbitrarily complex occluders and receivers. This paper introduces the penumbra map, ...

    • Translucent Shadow Maps 

      Dachsbacher, Carsten; Stamminger, Marc (The Eurographics Association, 2003)
      Shadow maps are a very efficient means to add shadows to arbitrary scenes. In this paper, we introduce Translucent Shadow Maps, an extension to shadow maps which allows very efficient rendering of sub-surface scattering. ...

    • The Trilateral Filter for High Contrast Images and Meshes 

      Choudhury, Prasun; Tumblin, Jack (The Eurographics Association, 2003)
      We present a new, single-pass nonlinear filter for edge-preserving smoothing and visual detail removal for N dimensional signals in computer graphics, image processing and computer vision applications. Built from two ...

    • Visualization of woven cloth 

      Adabala, Neeharika; Magnenat-Thalmann, Nadia; Fei, Guangzheng (The Eurographics Association, 2003)
      A technique for visualizing clothes is proposed that can handle rendering of complex weave patterns. An industrial standard of weave representation is used to derive the weave pattern and a detailed model of light interaction ...

    • Wavelet Environment Matting 

      Peers, Pieter; Dutré, Philip (The Eurographics Association, 2003)
      In this paper we present a novel approach for capturing the environment matte of a scene. We impose no restrictions on material properties of the objects in the captured scene and exploit scene characteristics (e.g. material ...

    • Efficient and Realistic Visualization of Cloth 

      Sattler, Mirko; Sarlette, Ralf; Klein, Reinhard (The Eurographics Association, 2003)
      Efficient and realistic rendering of cloth is of great interest especially in the context of e-commerce. Aside from the simulation of cloth draping, the rendering has to provide the "look and feel" of the fabric itself. ...

    • A New Reconstruction Filter for Undersampled Light Fields 

      Stewart, J.; Yu, J.; Gortler, S.J.; McMillan, L. (The Eurographics Association, 2003)
      This paper builds on previous research in the light field area of image-based rendering. We present a new reconstruction filter that significantly reduces the "ghosting" artifacts seen in undersampled light fields, while ...

    • Capturing and Rendering With Incident Light Fields 

      Unger, J.; Wenger, A.; Hawkins, T.; Gardner, A.; Debevec, P. (The Eurographics Association, 2003)
      This paper presents a process for capturing spatially and directionally varying illumination from a real-world scene and using this lighting to illuminate computer-generated objects. We use two devices for capturing such ...

    • Interactive Rendering of Translucent Deformable Objects 

      Mertens, Tom; Kautz, Jan; Bekaert, Philippe; Seidel, Hans-Peter; Reeth, Frank Van (The Eurographics Association, 2003)
      Realistic rendering of materials such as milk, fruits, wax, marble, and so on, requires the simulation of subsurface scattering of light. This paper presents an algorithm for plausible reproduction of subsurface scattering ...

    • Rendering Time Estimation for Real-Time Rendering 

      Wimmer, Michael; Wonka, Peter (The Eurographics Association, 2003)
      This paper addresses the problem of estimating the rendering time for a real-time simulation. We study different factors that contribute to the rendering time in order to develop a framework for rendering time estimation. ...
