    • Information Theory Tools for Scene Discretization 

      Feixas, Miquel; Acebo, Esteve del; Bekaert, Philippe; Sbert, Mateu (The Eurographics Association, 1999)
      Finding an optimal discretization of a scene is an important but difficult problem in radiosity. The efficiency of hierarchical radiosity for instance, depends entirely on the subdivision criterion and strategy that is ...

    • 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 ...

    • Towards Interactive Photorealistic Rendering of Indoor Scenes: A Hybrid Approach 

      Udeshi, Tushar; Hansen, Charles D. (The Eurographics Association, 1999)
      Photorealistic rendering methods produce accurate solutions to the rendering equation but are computationally expensive and typically noninteractive. Some researchers have used graphics hardware to obtain photorealistic ...

    • Group Accelerated Shooting Methods for Radiosity 

      Rousselle, Francois; Renaud, Christophe (The Eurographics Association, 1999)
      The introduction of the Progressive Refinement method was the starting point of interactivity in the radiosity illumination process. Overshooting methods brought an important acceleration to the convergence particularly ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...
