• Lighting Design: A Goal Based Approach Using Optimisation 

  Costa, António Cardoso; Sousa, António Augusto; Ferreira, Fernando Nunes (The Eurographics Association, 1999)

  There is a need for reliable lighting design applications because available tools are limited and inappropriate for interactive or creative use. Architects and lighting designers need those applications to define, predict, ...

• 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 ...

• Effective Compression Techniques for Precomputed Visibility 

  Panne, Michiel van de; Stewart, A. James (The Eurographics Association, 1999)

  In rendering large models, it is important to identify the small subset of primitives that is visible from a given viewpoint. One approach is to partition the viewpoint space into viewpoint cells, and then precompute a ...

• 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 ...

• Face Cluster Radiosity 

  Willmott, Andrew J.; Heckbert, Paul S.; Garland, Michael (The Eurographics Association, 1999)

  An algorithm for simulating diffuse interreflection in complex three dimensional scenes is described. It combines techniques from hierarchical radiosity and multiresolution modelling. A new face clustering technique for ...

• Rendering Inhomogeneous Surfaces with Radiosity 

  Mostefaoui, L.; Dischler, J.M.; Ghazanfarpour, D. (The Eurographics Association, 1999)

  Natural surfaces are often complex: they nearly always exhibit small scale imperfections such as dirt, dust, cracks, etc., as well as large scale structural elements, as for wickerwork, brick walls, textiles, pebbles, etc., ...

• 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 ...

• An Illumination Model for a System of Isotropic Substrate- Isotropic Thin Film with Identical Rough Boundaries 

  Icart, Isabelle; Arqués, Didier (The Eurographics Association, 1999)

  A new physically-based illumination model describing the interaction of light with a system composed of an isotropic substrate coated by an isotropic film with geometrically identical statistical rough boundaries (ITF) is ...

• 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 ...

• 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 ...

• Reducing Memory Requirements for Interactive Radiosity Using Movement Prediction 

  Schöffel, Frank; Pomi, Andreas (The Eurographics Association, 1999)

  The line-space hierarchy is a very powerful approach for the efficient update of radiosity solutions according to geometry changes. However, it suffers from its enormous memory consumption when storing shafts for the entire ...

• Approximating the Location of Integrand Discontinuities for Penumbral Illumination with Area Light Sources 

  Ouellette, Marc J.; Fiume, Eugene (The Eurographics Association, 1999)

  The problem of computing soft shadows with area light sources has received considerable attention in computer graphics. In part, this is a difficult problem because the integral that defines the radiance at a point must ...

• 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 ...

• Efficient Displacement Mapping by Image Warping 

  Schaufler, Gernot; Priglinger, Markus (The Eurographics Association, 1999)

  While displacement maps can provide a rich set of visual detail on otherwise simple surfaces, they have always been very expensive to render. Rendering has been done using ray-tracing and by introducing a great number of ...

• 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, ...

• 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 ...

• 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 ...

  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 ...

• Geospecific rendering of alpine terrain 

  Premoze, Simon; Thompson, William B.; Shirley, Peter (The Eurographics Association, 1999)

  Realistic rendering of outdoor terrain requires both that the geometry of the environment be modeled accurately and that appropriate texturing be laid down on top of that geometry. While elevation data is widely available ...
