Effective Compression Techniques for Precomputed Visibility
(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 ... -
Efficient Displacement Mapping by Image Warping
(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 ... -
Face Cluster Radiosity
(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 ... -
Gathering for Free in RandomWalk Radiosity
(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 ... -
Geospecific rendering of alpine terrain
(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 ... -
Group Accelerated Shooting Methods for Radiosity
(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
(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 ... -
An Illumination Model for a System of Isotropic Substrate- Isotropic Thin Film with Identical Rough Boundaries
(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 ... -
Image-Based BRDF Measurement Including Human Skin
(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 ... -
Information Theory Tools for Scene Discretization
(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 ... -
Interactive Ray-Traced Scene Editing Using Ray Segment Trees
(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 ... -
Interactive Rendering using the Render Cache
(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 Rendering with Arbitrary BRDFs using Separable Approximations
(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 ... -
Interactive Virtual Relighting and Remodeling of Real Scenes
(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 ... -
Light Field Techniques for Reflections and Refractions
(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 ... -
Lighting Design: A Goal Based Approach Using Optimisation
(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, ... -
Multiple Textures Stitching and Blending on 3D Objects
(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 ... -
Perceptually-informed accelerated rendering of high quality walkthrough sequences
(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 ... -
Real-Time Rendering of Real World Environments
(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 ... -
Reducing Memory Requirements for Interactive Radiosity Using Movement Prediction
(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 ...
