Adaptive Acquisition of Lumigraphs from Synthetic Scenes
(Blackwell Publishers Ltd and the Eurographics Association, 1999)Light fields and Lumigraphs are capable of rendering scenes of arbitrary geometrical or illumination complexity in real time. They are thus interesting ways of interacting with both recorded real-world and high-quality ... -
An Adaptive Method for Area Light Sources and Daylight in Ray Tracing
(Blackwell Publishers Ltd and the Eurographics Association, 1999)This paper proposes an adaptive method for taking both (diffuse or not) planar area light sources and daylight into account in a ray tracing environment which separates the calculation of direct and indirect illumination. ... -
Capturing and Re-Using Rendition Styles for Non-Photorealistic Rendering
(Blackwell Publishers Ltd and the Eurographics Association, 1999)Rendering high-quality non-photorealistic images of a given geometric model is often associated with a considerable amount of effort on the part of a user to fine-tune the rendition. In this paper we introduce a method and ... -
Compact Metallic Reflectance Models
(Blackwell Publishers Ltd and the Eurographics Association, 1999)The paper presents simple, physically plausible, but not physically based reflectance models for metals and other specular materials. So far there has been no metallic BRDF model that is easy to compute, suitable for fast ... -
Comprehensive Halftoning of 3D Scenes
(Blackwell Publishers Ltd and the Eurographics Association, 1999)The display of images on binary output hardware requires a halftoning step. Conventional halftoning algorithms approximate image values independently from the image content and often introduce artificial texture that ... -
Computer-Generated Graphite Pencil Rendering of 3D Polygonal Models
(Blackwell Publishers Ltd and the Eurographics Association, 1999)Researchers in non-photorealistic rendering have investigated the display of three-dimensional worlds using various display models. In particular, recent work has focused on the modeling of traditional artistic media and ... -
Creating Architectural Models from Images
(Blackwell Publishers Ltd and the Eurographics Association, 1999)We present methods for creating 3D graphical models of scenes from a limited numbers of images, i.e. one or two, in situations where no scene co-ordinate measurements are available. The methods employ constraints available ... -
Data Intermixing and Multi-volume Rendering
(Blackwell Publishers Ltd and the Eurographics Association, 1999)The main difference between multi-volume rendering and mono-volume rendering is data intermixing. In this paper, we present three levels of data intermixing and their rendering pipelines in direct multi-volume rendering, ... -
The Digital Michelangelo Project
(Blackwell Publishers Ltd and the Eurographics Association, 1999) -
An Efficient 2? D rendering and Compositing System
(Blackwell Publishers Ltd and the Eurographics Association, 1999)We describe a method for doing image compositing using either 2D geometric shapes or raster images as input primitives. The resolution of the final image is virtually unlimited but, as no frame buffer is used, performance ... -
An Efficient and Flexible Perception Pipeline for Autonomous Agents
(Blackwell Publishers Ltd and the Eurographics Association, 1999)Agents in virtual environments require a combination of perception and action to behave in an autonomous way. We extend a software architecture for the management of actions blending, called AGENTlib, with a perception ... -
Efficient and Handy Texture Mapping on 3D Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 1999)There has been a rapid technical progress in three-dimensional (3D) computer graphics. But gathering surface and texture data is yet a laborious task. This paper addresses the problem of mapping photographic images on the ... -
Fast Lines: a Span by Span Method
(Blackwell Publishers Ltd and the Eurographics Association, 1999)Straight line's scan conversion and drawing is a major field in computer graphics. Algorithm's time computation is very important. Nowadays, most of research papers suggest improvements of the DDA method that was first ... -
Fast Polyhedral Cell Sorting for Interactive Rendering of Unstructured Grids
(Blackwell Publishers Ltd and the Eurographics Association, 1999)Direct volume rendering based on projective methods works by projecting, in visibility order, the polyhedral cells of a mesh onto the image plane, and incrementally compositing the cell's color and opacity into the final ... -
A Free Form Feature Taxonomy
(Blackwell Publishers Ltd and the Eurographics Association, 1999)In this paper the notion of free form feature for aesthetic design is presented. The design of industrial products constituted by free form surfaces is done by using CAD systems representing curves and surfaces by means ... -
Generalized View-Dependent Simplification
(Blackwell Publishers Ltd and the Eurographics Association, 1999)We propose a technique for performing view-dependent geometry and topology simplifications for level-of-detail-based renderings of large models. The algorithm proceeds by preprocessing the input dataset into a binary tree, ... -
The Hybrid World of Virtual Environments
(Blackwell Publishers Ltd and the Eurographics Association, 1999)Much of the work concerned with virtual environments has addressed the development of new rendering technologies or interaction techniques. As the technology matures and becomes adopted in a wider range of applications, ... -
Image Morphing with Feature Preserving Texture
(Blackwell Publishers Ltd and the Eurographics Association, 1999)Image metamorphosis as an animation tool has mostly been employed in the context of the entire image. This work explores the use of isolated and focused image based metamorphosis between two-dimensional objects, while ... -
Improved Laplacian Smoothing of Noisy Surface Meshes
(Blackwell Publishers Ltd and the Eurographics Association, 1999)This paper presents a technique for smoothing polygonal surface meshes that avoids the well-known problem of deformation and shrinkage caused by many smoothing methods, like e.g. the Laplacian algorithm. The basic idea is ...
