Hipervídeo na Preservação e Partilha de Memória Cultural e Etnográfica
(The Eurographics Association, 2021)A cultura local originou sempre diversificados níveis de representação. Recolhas textuais, documentais, registos fotográficos, fonográficos ou cinematográficos, contribuíram para preservar a memória dos povos. No passado, ... -
Hoops Fusion: Synthesis of View-dependent Convex Occluders from a Set of Objects
(The Eurographics Association, 2022)Visibility determination is a requirement to navigate through complex scenes. Occluder fusion algorithms generate convex occluders that are contained in the umbra cast by a group of objects given an area light. Hoops are ... -
Horizonte Flutuante para Superfícies Paramétricas
(The Eurographics Association, 2023)Neste trabalho descreve-se uma adaptação feita do algoritmo de eliminação de linhas · ocultas denominado "do horizonte flutuante" (' floating horizon'). para tratar o caso das superfícies paramétricas. de Bézier em particular. ... -
How to Deal with Motion Sickness in Virtual Reality
(The Eurographics Association, 2020)In this paper we present a exploratory study on the physiological responses when experiencing motion sickness in Virtual Reality (VR). To this end, we developed a VR application that can induce motion sickness. Using it, ... -
HT-based Recognition of Patterns on 3D Shapes Using a Dictionary of Mathematical Curves
(The Eurographics Association, 2019)Characteristic curves play a fundamental role in the way a shape is perceived and illustrated. To address the curve recognition problem on surfaces, we adopt a generalisation of the Hough Transform (HT) which is able to ... -
Human Motion Analysis Tools
(The Eurographics Association, 2021)Análise de movimento é actualmente um tópico de pesquisa bastante activo nas áreas da Visão por Computador, Computação Gráfica e Biomecânica, devido `a sua aplicabilidade num vasto espectro de aplicações em diversas áreas. ... -
Human Robot Interaction in Virtual Reality
(The Eurographics Association, 2007)In this paper, we describe a framework which helps designers visualize and verify the results of robotic work cell simulation in a Virtual Environment (VE). The system aims at significantly reducing production costs and ... -
The Human-Computer Interfaces Course at IST
(The Eurographics Association, 2023)This paper presents the main and most relevant aspects of the Human-Computer Interfaces course lectured for the 4th academic years (and fifth year as an optional course) of the undergraduate program in lnformatics and ... -
Human-in-the-Loop Visualisation Architecture for Monitoring Remote Compute
(The Eurographics Association, 2017)This paper describes the timeline of use cases of large and remote display VEs (Virtual Environments), hosted by STFC (Science and Technology Facilities Council), which were linked to HPC (High Performance Computing) ... -
Humanos Virtuais na Plataforma IViHumans - a Odisseia da Integração de Ferramentas
(The Eurographics Association, 2021)A modelação e a animação de humanos virtuais são tarefas morosas. Apesar de complexa, a integração de diferentes componentes de software é um processo expedito para a construção de humanos virtuais porque permite congregar ... -
Hybrid Data-Parallel Contour Tree Computation
(The Eurographics Association, 2016)As data sets increase in size beyond the petabyte, it is increasingly important to have automated methods for data analysis and visualisation. While topological analysis tools such as the contour tree and Morse-Smale complex ... -
Hyperquadrics for Shape Analysis of 3D Nanoscale Reconstructions of Brain Cell Nuclear Envelopes
(The Eurographics Association, 2018)Shape analysis of cell nuclei is becoming increasingly important in biology and medicine. Recent results have identified that the significant variability in shape and size of nuclei has an important impact on many biological ... -
HyperStreamball Visualization for Symmetric Second Order Tensor Fields
(The Eurographics Association, 2006)This paper proposes a new 3D tensor glyph called a hyperstreamball that extends streamball visualization used within fluid flow fields to applications within second order tensor fields. The hyperstreamball is a hybrid of ... -
I-UsE: Integrated Usability Evaluation Environment
(The Eurographics Association, 2021)Software usability evaluation (UE) is a typically neglected phase by software developers. Due to the high costs of properly done formal usability studies, companies easily cut investment, contributing deliberately to the ... -
An Icon User Interface For Geometric Modelling
(The Eurographics Association, 2023)The User Interface plays a very important role in the geometric modelling systems. Different approaches have been developed in the last years, with and without the use of graphic images. As the sight is the most important ... -
ID-Based Rendering of Silhouettes on GPU
(The Eurographics Association, 2010)When rendering object-silhouettes preprocessing is generally done primarily on the CPU. To this end primitive normals must be made consistent and the silhouette-edges need to be extracted every time the view-point is ... -
Identificação de Objetos em Imagens Tomográficas através de GPGPUs
(The Eurographics Association, 2021)Neste artigo encontra-se a implementação e a avaliação de um novo algoritmo híbrido (CPU-GPU) para a identificação de estruturas conexas em volumes de dados tridimensionais. Este algoritmo explora o paralelismo tanto ao ... -
