    • Perceptually-informed accelerated rendering of high quality walkthrough sequences 

      Myszkowski, Karol; Rokita, Przemyslaw; Tawara, Takehiro (The Eurographics Association, 1999)
      In this paper, we consider accelerated rendering of walkthrough animation sequences using combination of ray tracing and Image-Based Rendering (IBR) techniques. Our goal is to derive as many pixels as possible using ...
    • Space-Time Hierarchical Radiosity 

      Damez, Cyrille; Sillion, Francois (The Eurographics Association, 1999)
      This paper presents a new hierarchical simulation algorithm allowing the calculation of radiosity solutions for time-dependent scenes where all motion is known a priori. Such solutions could, for instance, be computed to ...
    • Multiple Textures Stitching and Blending on 3D Objects 

      Rocchini, C.; Cignoni, P.; Montani, C.; Scopigno, R. (The Eurographics Association, 1999)
      In this paper we propose a new approach for mapping and blending textures on 3D geometries. The system starts from a 3D mesh which represents a real object and improves this model with pictorial detail. Texture detail is ...
    • Beyond Photorealism 

      Green, Stuart (The Eurographics Association, 1999)
      For around 30 years the computer graphics research community has pursued photorealism as though it were the ultimate form of visual expression. Yet, as an art form, photorealism is one of many abstrations that an artist ...
    • Interactive Rendering with Arbitrary BRDFs using Separable Approximations 

      Kautz, Jan; McCool, Michael D. (The Eurographics Association, 1999)
      A separable decomposition of bidirectional reflectance distributions (BRDFs) is used to implement arbitrary reflectances from point sources on existing graphics hardware. Two-dimensional texture mapping and compositing ...
    • Computing Visibility for Triangulated Panoramas 

      Fu, Chi-Wing; Wong, Tien-Tsin; Heng, Pheng-Ann (The Eurographics Association, 1999)
      A visibility algorithm for triangulated panoramas is proposed. The algorithm can correctly resolve the visibility without making use of any depth information. It is especially useful when depth information is not available, ...
    • Rendering of Wet Materials 

      Jensen, Henrik Wann; Legakis, Justin; Dorsey, Julie (The Eurographics Association, 1999)
      The appearance of many natural materials is largely influenced by the environment in which they are situated. Capturing the effects of such environmental factors is essential for producing realistic synthetic images. In ...
    • Hierarchical Image-Based Rendering using Texture Mapping Hardware 

      Max, Nelson; Deussen, Oliver; Keating, Brett (The Eurographics Association, 1999)
      Multi-layered depth images containing color and normal information for subobjects in a hierarchical scene model are precomputed with standard zbuffer hardware for six orthogonal views. These are adaptively selected according ...
    • Shadow Penumbras for Complex Objects by Depth-Dependent Filtering of Multi-Layer Depth Images 

      Keating, Brett; Max, Nelson (The Eurographics Association, 1999)
      This paper presents an efficient algorithm for filtering multi-layer depth images (MDIs) in order to produce approximate penumbras. The filtering is performed on a MDI that represents the view from the light source. The ...
    • Light Field Techniques for Reflections and Refractions 

      Heidrich, Wolfgang; Lensch, Hendrik; Cohen, Michael F.; Seidel, Hans-Peter (The Eurographics Association, 1999)
      Reflections and refractions are important visual effects that have long been considered too costly for interactive applications. Although most contemporary graphics hardware supports reflections off curved surfaces in the ...
    • Gathering for Free in RandomWalk Radiosity 

      Sbert, Mateu; Brusi, Alex; Bekaert, Philippe (The Eurographics Association, 1999)
      We present a simple technique that improves the efficiency of random walk algorithms for radiosity. Each generated random walk is used to simultaneously sample two distinct radiosity estimators. The first estimator is the ...
    • Interactive Virtual Relighting and Remodeling of Real Scenes 

      Loscos, Céline; Frasson, Marie-Claude; Drettakis, George; Walter, Bruce; Granier, Xavier; Poulin, Pierre (The Eurographics Association, 1999)
      Lighting design is often tedious due to the required physical manipulation of real light sources and objects. As an alternative, we present an interactive system to virtually modify the lighting and geometry of scenes with ...
    • Interactive Ray-Traced Scene Editing Using Ray Segment Trees 

      Bala, Kavita; Dorsey, Julie; Teller, Seth (The Eurographics Association, 1999)
      This paper presents a ray tracer that facilitates near-interactive scene editing with incremental rendering; the user can edit the scene both by manipulating objects and by changing the viewpoint. Our system uses object-space ...
    • Disruptive Technologies in Computer Graphics: Past, Present, and Future 

      Greenberg, Donald P. (The Eurographics Association, 1999)
      The history and famous landmarks of computer graphics hardware are well known. Starting with Ivan Sutherland s Sketchpad system in the early 1960 s, the first generation of computer graphics hardware consisted of calligraphic ...
    • Interactive Rendering using the Render Cache 

      Walter, Bruce; Drettakis, George; Parker, Steven (The Eurographics Association, 1999)
      Interactive rendering requires rapid visual feedback. The render cache is a new method for achieving this when using high-quality pixel-oriented renderers such as ray tracing that are usually considered too slow for ...
    • Image-Based BRDF Measurement Including Human Skin 

      Marschner, Stephen R.; Westin, Stephen H.; Lafortune, Eric P. F.; Torrance, Kenneth E.; Greenberg, Donald P. (The Eurographics Association, 1999)
      We present a new image-based process for measuring the bidirectional reflectance of homogeneous surfaces rapidly, completely, and accurately. For simple sample shapes (spheres and cylinders) the method requires only a ...
    • Real-Time Rendering of Real World Environments 

      McAllister, David K.; Nyland, Lars; Popescu, Voicu; Lastra, Anselmo; McCue, Chris (The Eurographics Association, 1999)
      One of the most important goals of interactive computer graphics is to allow a user to freely walk around a virtual recreation of a real environment that looks as real as the world around us. But hand-modeling such a virtual ...
    • Decoupling Polygon Rendering from Geometry using Rasterization Hardware 

      Westermann, Rüdiger; Sommer, Ove; Ertl, Thomas (The Eurographics Association, 1999)
      The dramatically increasing size of polygonal models resulting from 3D scanning devices and advanced modeling techniques requires new approaches to reduce the load of geometry transfer and processing. In order to supplement ...
