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 ...
