Area Sampling Buffer: Tracing Rays with Z-Buffer Hardware
(Blackwell Science Ltd and the Eurographics Association, 1992)An algorithm that allows the use of z-buffer hardware in assisting area sampling for a ray tracing style renderer is described. The implementation issues involved in discretizing the sampling area and light source area are ... -
Area-Preserving Parameterizations for Spherical Ellipses
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present new methods for uniformly sampling the solid angle subtended by a disk. To achieve this, we devise two novel area-preserving mappings from the unit square [0;1]2 to a spherical ellipse (i.e. the projection of ... -
An Area-Preserving Parametrization for Spherical Rectangles
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present an area-preserving parametrization for spherical rectangles which is an analytical function with domain in the unit rectangle [0;1]2 and range in a region included in the unit-radius sphere. The parametrization ... -
ARENA and WOXBOT: Some Steps towards the Animation of Cognitive Characters Acting in a Virtual World
(The Eurographics Association, 2022)This paper reports some of the results of the WOXBOT / ARENA project on artificial life. This project to build virtual worlds was set initially aimed at the graphic simulation of an arena where WoxBots, small mobile robots, ... -
The Arena: An lndoor Mixed Reality Space
(The Eurographics Association, 2021)ln this paper we introduce the Arena, an indoor space for mobile mixed reality interaction. The Arena, includes a new user tracking system appropriate for ARJMR applications anda new Too/kit oriented to the augmented and ... -
The ARGOSI Classification Scheme for Graphics and Networking Applications
(Blackwell Science Ltd and the Eurographics Association, 1993)ARGOSI is a project concerned with the relationship between standards for graphics and networking, as rejected in its full title: Applications Related Graphics and OSI Standards Integration. It is a collaborative project ... -
An Argument Structure for Data Stories
(The Eurographics Association, 2017)Many data stories in journalism do not have a story arc, but rather present facts without much structure. This mirrors the popular inverted pyramid style of writing that presents the most important information up front, ... -
ARGUS: Interactive Visual Analytics Framework for the Discovery of Disruptions in Bio-Behavioral Rhythms
(The Eurographics Association, 2020)Human Bio-Behavioral Rhythms (HBRs) such as sleep-wake cycles and their regularity have important health ramifications. Smartphones can sense HBRs by gathering and analyzing data from built-in sensors, which provide ... -
ARIS - A Robotic Approach to Digitization of Indoor and Underground Cultural Heritage Sites
(IEEE, 2015)A robot to digitize indoor and underground cultural heritage sites: a novel approach for acquiring and managing digital models of archaeological sites. Three technologies will be presented for this occasion: a robotic ... -
ARK multi-utilizador
(The Eurographics Association, 2021)This paper present a monitor based prototype for visualization and interaction of an Augmented Reality (AR) system. It had been recently developed at CCG and demonstrated on the conference SIACG2002 at Guimarães, Portugal. ... -
Arm Swinging vs Treadmill: A Comparison Between Two Techniques for Locomotion in Virtual Reality
(The Eurographics Association, 2018)When it comes to locomotion in Virtual Reality (VR), a wide range of different techniques has been proposed in the scientific literature or as commercial products. However, the best choice for a specific application is ... -
The Arnolfini Portrait in 3D - Creating Virtual World of a Painting with Inconsistent Perspective
(The Eurographics Association, 2007)We report on creating a 3d virtual reconstruction of the scene shown in "The Arnolfini Portrait" by Jan van Eyck. This early Renaissance painting, if painted faithfully, should confirm to one-point perspective, however it ... -
Arquitectura para Simulação de Classes de Animais em Realidade Virtual
(The Eurographics Association, 2023)Pretende-se obter a visualização e a simulação, num ambiente de realidade virtual, de animais de diferentes espécies habitando um mesmo ecossistema. Esta comunicação propõe uma arquitectura de suporte com a finalidade de ... -
An array based design for Real-Time Volume Rendering
(The Eurographics Association, 1995)This paper describes a new algorithm and hardware design for the generation of two dimensional images from volume data using the ray casting technique. The algorithm is part of an image generation system that is broken ... -
The Arrigo Showcase Reloaded - towards a sustainable link between 3D and semantics
(The Eurographics Association, 2008)It is still a big technical problem to establish a relation between a shape and its meaning in a sustainable way. We present a solution with a markup method that allows to label parts of a 3D object in a similar way to ... -
ARrow: A Real-Time AR Rowing Coach
(The Eurographics Association, 2023)Rowing requires physical strength and endurance in athletes as well as a precise rowing technique. The ideal rowing stroke is based on biomechanical principles and typically takes years to master. Except for time-consuming ... -
The Art and Science of Digital Production Arts
(The Eurographics Association, 2011)As its name implies, digital production arts incorporates both technical and artistic aspects. The challenge of any program in this discipline is to balance these two components in such a way that each enhances the other ... -
An Art-based Approach to Visual Analytics
(The Eurographics Association, 2016)In this paper, we propose an art-based approach to visual analytics.We argue that while artistic data visualizations have mainly been designed to communicate the artist's message, certain artistic styles can be very effective ... -
