On the Fractal Behaviour of AA Patterns
(The Eurographics Association, 2012)''AA Patterns'' is a recently discovered kind of algorithmic art in the form of pixel patterns; where each pixel in a 2D bitmap is set or unset according to a simple test applied to its coordinates pair. In spite of their ... -
On the Impact of Training HRTF-Based Auralisation
(The Eurographics Association, 2021)Auralisation with generic, non-individualised, Head Related Transfer Functions (HRTF) is common practice, as obtaining individualised HRTFs poses very serious practical difficulties. It is therefore extremely important to ... -
On the road to Rich Digital Books
(The Eurographics Association, 2021)This article presents an architecture for producing rich digital books. These are books enriched with supporting media, like images and sound, to reach broader audiences and enlarge their usage possibilities. The architecture ... -
Online Communication in a Multimedia Course
(The Eurographics Association, 2021)Communication is a critical component of human interaction in order to satisfy basic human needs. This is especially true in technology-supported learning environments, where establishing multiple communicational channels ... -
Online Education
(The Eurographics Association, 2023)New technologies for distance Jearning through the Web, vídeo conferencing, collaborative working toais have the potential to enhance and extend learning. This requires a large leap for many institutions, teachers and ... -
Open Source Debuggers and Integration with a 3D Engine
(The Eurographics Association, 2020)Debugging is always an important phase in an application life. Applications using 3D hardware accelerated graphics in general, and OpenGL in particular, are usually hard to debug since the computation is split between two ... -
Operações Morfológicas sobre Imagens Segmentadas
(The Eurographics Association, 2023)A remoção de ruído em imagens binárias pode ser efectuada pela aplicação de sucessivas operações morfológicas [Har87]. É proposta uma extensão simples, para imagens segmentadas, das operações morfológicas elementares de ... -
Optimal Software-based Projector Alignment
(The Eurographics Association, 2022)We present a software-based method for alignment of projectors, both for side-by-side (mosaic) and stereo projections. The projectors are assumed to be positioned in such a way that their axes are not perpendicular to the ... -
Optimising Underwater Environments for Mobile VR
(The Eurographics Association, 2019)Mobile Virtual Reality (VR) has advanced considerably in the last few years, driven by advances in smartphone technology. There are now a number of commercial offerings available, from smartphone powered headsets to ... -
Optimización del Cálculo de Colisiones para Mallas Deformables mediante Voxelización de Primitivas
(The Eurographics Association, 2008)Este artículo propone una optimización para la detección de colisiones de objetos deformables, consistente en la voxelización eficiente de primitivas en particiones espaciales. Nuestra técnica tiene aplicabilidad en el ... -
Optimização de Próteses Ortopédicas
(The Eurographics Association, 2023)Os benefícios resultantes da utilização de sistemas informáticos em actividades relacionadas com o Projecto, dependem em grande parte do ambiente de trabalho posto à disposição do projectista, das respectivas técnicas de ... -
An Optimized Marker Layout for 3D Facial Motion Capture
(The Eurographics Association, 2018)Facial motion capture (Facial Mocap) has gained increasing attention from researchers and professionals from different areas of interest, including entertainment, face-to-face communication, and training. Facial Mocap ... -
Optimizing Placements of 360° Panoramic Cameras in Indoor Environments by Integer Programming
(The Eurographics Association, 2022)We propose a computational approach to find a minimal set of 360° camera placements that together sufficiently cover an indoor environment for the building documentation problem in the architecture, engineering, and ... -
Ordering Triangles in Triangulated Terrains Over Regular Grids
(The Eurographics Association, 2016)In this work we report on a set of rules to visit triangles in triangulated height fields defined over regular grids in a back-to- front order with respect to an arbitrary viewpoint. With the viewpoint, we associate an ... -
Organização Participada de Informação Hipertextual sobre Cadeiras
(The Eurographics Association, 2023)Este documento apresenta o desenho de uma infraestrutura hipertextual genérica de uma cadeira. O objectivo pretendido consistiu em: (1) definir uma infraestrutura reutilizável; (2) incrementar a produtividade do processo ... -
ORQA: Objective Reflection Quality Assessment
(The Eurographics Association, 2020)We present ORQA (Objective Reflection Quality Assessment), a method to objectively assess shape quality from reflection line renderings. The goal of ORQA is to correctly order existing comparable reflection line renderings ... -
