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, ... -
Decoupling Polygon Rendering from Geometry using Rasterization Hardware
(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 ... -
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 ... -
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 ... -
Space-Time Hierarchical Radiosity
(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
(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
(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 ... -
Beyond Photorealism
(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
(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
(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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Approximating the Location of Integrand Discontinuities for Penumbral Illumination with Area Light Sources
(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 ... -
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 ... -
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 ... -
Disruptive Technologies in Computer Graphics: Past, Present, and Future
(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 ... -
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 ...
