    • Accelerating Path Tracing by Re-Using Paths 

      Bekaert, Philippe; Sbert, Mateu; Halton, John (The Eurographics Association, 2002)
      This paper describes a new acceleration technique for rendering algorithms like path tracing, that use so called gathering random walks. Usually in path tracing, each traced path is used in order to compute a contribution ...

    • Accelerating Ray Tracing using Constrained Tetrahedralizations 

      Lagae, Ares; Dutre, Philip (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we introduce the constrained tetrahedralization as a new acceleration structure for ray tracing. A constrained tetrahedralization of a scene is a tetrahedralization that respects the faces of the scene geometry. ...

    • Accurate Fitting of Measured Reflectances Using a Shifted Gamma Micro-facet Distribution 

      Bagher, Mohammad Mahdi; Soler, Cyril; Holzschuch, Nicolas (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Material models are essential to the production of photo-realistic images. Measured BRDFs provide accurate representation with complex visual appearance, but have larger storage cost. Analytical BRDFs such as Cook- Torrance ...

    • Acquisition and Rendering of Transparent and Refractive Objects 

      Matusik, Wojciech; Pfister, Hanspeter; Ziegler, Remo; Ngan, Addy; McMillan, Leonard (The Eurographics Association, 2002)
      This paper introduces a new image-based approach to capturing and modeling highly specular, transparent, or translucent objects. We have built a system for automatically acquiring high quality graphical models of objects ...

    • 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, ...

    • Adaptive Numerical Cumulative Distribution Functions for Efficient Importance Sampling 

      Lawrence, Jason; Rusinkiewicz, Szymon; Ramamoorthi, Ravi (The Eurographics Association, 2005)
      As image-based surface reflectance and illumination gain wider use in physically-based rendering systems, it is becoming more critical to provide representations that allow sampling light paths according to the distribution ...

    • Adaptive Visibility-Driven View Cell Construction 

      Mattausch, Oliver; Bittner, Jirí; Wimmer, Michael (The Eurographics Association, 2006)
      We present a new method for the automatic partitioning of view space into a multi-level view cell hierarchy. We use a cost-based model in order to minimize the average rendering time. Unlike previous methods, our model ...

    • Adaptive Volumetric Shadow Maps 

      Salvi, Marco; Vidimce, Kiril; Lauritzen, Andrew; Lefohn, Aaron (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We introduce adaptive volumetric shadow maps (AVSM), a real-time shadow algorithm that supports high-quality shadowing from dynamic volumetric media such as hair and smoke. The key contribution of AVSM is the introduction ...

    • Alias-Free Shadow Maps 

      Aila, Timo; Laine, Samuli (The Eurographics Association, 2004)
      In this paper we abandon the regular structure of shadow maps. Instead, we transform the visible pixels P(x, y, z) from screen space to the image plane of a light source P0(x0, y0, z0). The (x0, y0) are then used as sampling ...

    • All-focused light field rendering 

      Kubota, Akira; Takahashi, Keita; Aizawa, Kiyoharu; Chen, Tsuhan (The Eurographics Association, 2004)
      We present a novel reconstruction method that can synthesize an all in-focus view from under-sampled light fields, significantly suppressing aliasing artifacts. The presented method consists of two steps; 1) rendering ...

    • All-Frequency Precomputed Radiance Transfer for Glossy Objects 

      Liu, Xinguo; Sloan, Peter-Pike; Shum, Heung-Yeung; Snyder, John (The Eurographics Association, 2004)
      We introduce a method based on precomputed radiance transfer (PRT) that allows interactive rendering of glossy surfaces and includes shadowing effects from dynamic, "all-frequency" lighting. Specifically, source lighting ...

    • All-Frequency Relighting of Non-Diffuse Objects using Separable BRDF Approximation 

      Wang, Rui; Tran, John; Luebke, David (The Eurographics Association, 2004)
      This paper presents a technique, based on pre-computed light transport and separable BRDF approximation, for interactive rendering of non-diffuse objects under all-frequency environment illumination. Existing techniques ...

    • Ambient Occlusion for Animated Characters 

      Kontkanen, Janne; Aila, Timo (The Eurographics Association, 2006)
      We present a novel technique for approximating ambient occlusion of animated objects. Our method automatically determines the correspondence between animation parameters and per-vertex ambient occlusion using a set of ...

    • Anaglyph Stereo Without Ghosting 

      Sanftmann, Harald; Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Anaglyph stereo provides a low-budget solution to viewing stereoscopic images. However, it may suffer from ghosting and bad color reproduction. Here we address the first issue. We present a novel technique to perceptually ...

    • An Analysis of the In-Out BRDF Factorization for View-Dependent Relighting 

      Mahajan, Dhruv; Tseng, Yu-Ting; Ramamoorthi, Ravi (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Interactive rendering with dynamic natural lighting and changing view is a long-standing goal in computer graphics. Recently, precomputation-based methods for all-frequency relighting have made substantial progress in this ...

    • Analytic Tangent Irradiance Environment Maps for Anisotropic Surfaces 

      Mehta, Soham Uday; Ramamoorthi, Ravi; Meyer, Mark; Hery, Christophe (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Environment-mapped rendering of Lambertian isotropic surfaces is common, and a popular technique is to use a quadratic spherical harmonic expansion. This compact irradiance map representation is widely adopted in interactive ...

    • An Analytical Model for Skylight Polarisation 

      Wilkie, A.; Ulbricht, C.; Tobler, Robert F.; Zotti, G.; Purgathofer, W. (The Eurographics Association, 2004)
      Under certain circumstances the polarisation state of the illumination can have a significant influence on the appearance of scenes; outdoor scenes with specular surfaces - such as water bodies or windows - under clear, ...

    • Animatable Facial Reflectance Fields 

      Hawkins, Tim; Wenger, Andreas; Tchou, Chris; Gardner, Andrew; Göransson, Fredrik; Debevec, Paul (The Eurographics Association, 2004)
      We present a technique for creating an animatable image-based appearance model of a human face, able to capture appearance variation over changing facial expression, head pose, view direction, and lighting condition. Our ...

    • Anomalous Dispersion in Predictive Rendering 

      Weidlich, Andrea; Wilkie, Alexander (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In coloured media, the index of refraction does not decrease monotonically with increasing wavelength, but behaves in a quite non-monotonical way. This behaviour is called anomalous dispersion and results from the fact ...

    • Anti-aliasing and Continuity with Trapezoidal Shadow Maps 

      Martin, Tobias; Tan, Tiow-Seng (The Eurographics Association, 2004)
      This paper proposes a new shadow map technique termed trapezoidal shadow maps to calculate high quality shadows in real-time applications. To address the resolution problem of the standard shadow map approach, our technique ...
