    • Enhancing and Optimizing the Render Cache 

      Walter, Bruce; Drettakis, George; Greenberg, Donald P. (The Eurographics Association, 2002)
      Interactive rendering often requires the use of simplified shading algorithms with reduced illumination fidelity. Higher quality rendering algorithms are usually too slow for interactive use. The render cache is a technique ...
    • Interactive Global Illumination Using Selective Photon Tracing 

      Dmitriev, Kirill; Brabec, Stefan; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association, 2002)
      We present a method for interactive global illumination computation which is embedded in the framework of Quasi-Monte Carlo photon tracing and density estimation techniques. The method exploits temporal coherence of ...
    • 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 ...
    • Fast Primitive Distribution for Illustration 

      Secord, Adrian; Heidrich, Wolfgang; Streit, Lisa (The Eurographics Association, 2002)
      In this paper we present a high-quality, image-space approach to illustration that preserves continuous tone by probabilistically distributing primitives while maintaining interactive rates. Our method allows for frame-to-frame ...
    • Spatio-Temporal View Interpolation 

      Vedula, Sundar; Baker, Simon; Kanade, Takeo (The Eurographics Association, 2002)
      We propose a fully automatic algorithm for view interpolation of a completely non-rigid dynamic event across both space and time. The algorithm operates by combining images captured across space to compute voxel models of ...
    • Image-based Environment Matting 

      Wexler, Yonatan; Fitzgibbon, Andrew. W.; Zisserman, Andrew. (The Eurographics Association, 2002)
      Environment matting is a powerful technique for modeling the complex light-transport properties of real-world optically active elements: transparent, refractive and reflective objects. Recent research has shown how environment ...
    • Towards Real-Time Texture Synthesis with the Jump Map 

      Zelinka, Steve; Garland, Michael (The Eurographics Association, 2002)
      While texture synthesis has been well-studied in recent years, real-time techniques remain elusive. To help facilitate real-time texture synthesis, we divide the task of texture synthesis into two phases: a relatively slow ...
    • Exact From-Region Visibility Culling 

      Nirenstein, S.; Blake, E.; Gain, J. (The Eurographics Association, 2002)
      To pre-process a scene for the purpose of visibility culling during walkthroughs it is necessary to solve visibility from all the elements of a finite partition of viewpoint space. Many conservative and approximate solutions ...
    • Synthesizing Bark 

      Lefebvre, Sylvain; Neyret, Fabrice (The Eurographics Association, 2002)
      Despite the high quality reached by today s CG tree generators, there exists no realistic model for generating the appearance of bark: simple texture maps are generally used, showing obvious flaws if the tree is not entirely ...
    • Microfacet Billboarding 

      Yamazaki, Shuntaro; Sagawa, Ryusuke; Kawasaki, Hiroshi; Ikeuchi, Katsushi; Sakauchi, Masao (The Eurographics Association, 2002)
      Rendering of intricately shaped objects that are soft or cluttered is difficult because we cannot accurately acquire their complete geometry. Since their geometry varies drastically, modeling them using fixed facets can ...
    • Approximate Soft Shadows on Arbitrary Surfaces using PenumbraWedges 

      Akenine-Möller, Tomas; Assarsson, Ulf (The Eurographics Association, 2002)
      Shadow generation has been subject to serious investigation in computer graphics, and many clever algorithms have been suggested. However, previous algorithms cannot render high quality soft shadows onto arbitrary, animated ...
    • Time Dependent Photon Mapping 

      Cammarano, Mike; Jensen, Henrik Wann (The Eurographics Association, 2002)
      The photon map technique for global illumination does not specifically address animated scenes. In particular, prior work has not considered the problem of temporal sampling (motion blur) while using the photon map. In ...
    • The Free-form Light Stage 

      Masselus, Vincent; Dutré, Philip; Anrys, Frederik (The Eurographics Association, 2002)
      We present the Free-form Light Stage, a system that captures the reflectance field of an object using a free-moving, hand-held light source. By photographing the object under different illumination conditions, we are able ...
    • Real-Time Halftoning: A Primitive For Non-Photorealistic Shading 

      Freudenberg, Bert; Masuch, Maic; Strothotte, Thomas (The Eurographics Association, 2002)
      We introduce halftoning as a general primitive for real-time non-photorealistic shading. It is capable of producing a variety of rendering styles, ranging from engraving with lighting-dependent line width to pen-and-ink ...
    • GigaWalk: Interactive Walkthrough of Complex Environments 

      III, William V. Baxter; Sud, Avneesh; Govindaraju, Naga K.; Manocha, Dinesh (The Eurographics Association, 2002)
      We present a new parallel algorithm and a system, GigaWalk, for interactive walkthrough of complex, gigabytesized environments. Our approach combines occlusion culling and levels-of-detail and uses two graphics pipelines ...
    • 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 ...
    • Fast, Arbitrary BRDF Shading for Low-Frequency Lighting Using Spherical Harmonics 

      Kautz, Jan; Sloan, Peter-Pike; Snyder, John (The Eurographics Association, 2002)
      Real-time shading using general (e.g., anisotropic) BRDFs has so far been limited to a few point or directional light sources. We extend such shading to smooth, area lighting using a low-order spherical harmonic basis for ...
    • Hardware-Accelerated Point-Based Rendering of Complex Scenes 

      Coconu, Liviu; Hege, Hans-Christian (The Eurographics Association, 2002)
      High quality point rendering methods have been developed in the last years. A common drawback of these approaches is the lack of hardware support. We propose a novel point rendering technique that yields good image quality ...
    • Picture Perfect RGB Rendering Using Spectral Prefiltering and Sharp Color Primaries 

      Ward, Greg; Eydelberg-Vileshin, Elena (The Eurographics Association, 2002)
      Accurate color rendering requires the consideration of many samples over the visible spectrum, and advanced rendering tools developed by the research community offer multispectral sampling towards this goal. However, for ...
    • Curve Analogies 

      Hertzmann, Aaron; Oliver, Nuria; Curless, Brian; Seitz, Steven M. (The Eurographics Association, 2002)
      This paper describes a method for learning statistical models of 2D curves, and shows how these models can be used to design line art rendering styles by example. A user can create a new style by providing an example of ...
