A New Method of Image Mosaicking and Its Application to Cultural Heritage Representation
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
This paper presents an original two-step procedure for estimating projective transformations between pairs of images: first, the transformation between the images is approximated as an affine transformation; second, this ...
Virtual Dunhuang Art Cave: A Cave within a CAVE
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
Virtual Reality can present historical places in a three-dimensional and interactive way, giving visitors a photorealistic impression of objects. Not only existing scenarios can be shown, but VR can also be used to rebuild ...
Stochastic Iteration for Non-diffuse Global Illumination
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
This paper presents a single-pass, view-dependent method to solve the rendering equation, using a stochastic iterational scheme where the transport operator is selected randomly in each iteration. The requirements of ...
Multi-layered impostors for accelerated rendering
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
This paper describes the successful combination of pre-generated and dynamically updated image-based representations to accelerate the visualization of complex virtual environments. We introduce a new type of impostor, ...
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 ...
An Information Theory Framework for the Analysis of Scene Complexity
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
In this paper we present a new framework for the analysis of scene visibility and radiosity complexity. We introduce a number of complexity measures from information theory quantifying how difficult it is to compute with ...
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 ...
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 ...
Weighted Multipass Methods for Global Illumination
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
In multipass rendering, care has to be taken to include all light transport only once in the final solution. Therefore the different methods in current multipass configurations handle a perfectly disjunct part of the light ...
An Interactive Designing System with Virtual Sculpting and Virtual Woodcut Printing
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
In this paper, we propose an interactive designing method and a system based on it to create 3D objects and 2D images. This system consists of two subsystems for virtual sculpting to create a 3D shape and virtual printing ...
