Perimeter Detection in Sketched Drawings of Polyhedral Shapes
(The Eurographics Association, 2017)This paper describes a new "envelope" approach for detecting object perimeters in line-drawings vectorised from sketches of polyhedral objects. Existing approaches for extracting contours from digital images are unsuitable ... -
Perlin Noise and 2D Second-Order Tensor Field Visualization
(The Eurographics Association, 2005)There has been much research in the use of texture for visulization the vector field data, whereas there has only been a few papers concerned specifically with tensor field data. This set is more complex and embeds more ... -
Persistent Homology and the Discrete Laplace Operator For Mesh Similarity
(The Eurographics Association, 2020)We use persistent homology along with the eigenfunctions of the Laplacian to study similarity amongst geometric and combinatorial objects. Our method relies on studying the lower-star filtration induced by the eigenfunctions ... -
Persistent Homology: a Step-by-step Introduction for Newcomers
(The Eurographics Association, 2016)Persistent homology is a powerful notion rooted in topological data analysis which allows for retrieving the essential topological features of an object. The attention on persistent homology is constantly growing in a large ... -
Personagens Virtuais Expressivas
(The Eurographics Association, 2020)A Ansiedade Social afeta um número significativo de pessoas, limitando-as na vida pessoal e social, e apresentando um nível de comorbilidade elevado com a depressão. Neste artigo descrevemos um projeto que aplica Realidade ... -
Personagens Virtuais na Terapia de Exposição
(The Eurographics Association, 2020)Neste artigo descreve-se uma aplicação de Realidade Virtual desenvolvida com o objetivo principal de apoiar no tratamento da ansiedade social relacionada com situações de avaliação perante um júri. A aplicação gera uma ... -
Personalised Authentic assessments with Synchronous Learning Activities: a Framework for Teaching Visualisation and Graphics
(The Eurographics Association, 2022)We present an activities framework for learning visualisation and computer graphics. The framework pivots around the academic developing an authentic learning scenario that is personalised for every student, followed by a ... -
PersonalNews: A Nossa Vida de Relance…
(The Eurographics Association, 2021)Com o aumento da quantidade de informação existente nos computadores pessoais, existe cada vez mais a necessidade de desenvolver novas formas de gerir essa informação. Apresentamos uma interface em que é possível visualizar ... -
Perspectivas para o Desenvolvimento de Sistemas CAD
(The Eurographics Association, 2023)Estamos a ser confrontados com uma mudança violenta no mundo empresarial, o que implica um novo papel a desempenhar pelos designers no quadro de um alinhamento gestão / design diferente do tradicional. A I&D na área dos ... -
Pesquisa de Imagens na Web: Estudo de Usabilidade
(The Eurographics Association, 2021)Os utilizadores de sistemas de pesquisa de imagens na Web expressam as suas necessidades através de interro- gações que descrevem as imagens pretendidas. A análise detalhada destas interrogações e a observação do comportamento ... -
Pesquisa de informação e cuidados pediátricos: Prototipagem de uma aplicação móvel de auxílio aos pais
(The Eurographics Association, 2020)A pesquisa online de informação médica é uma prática cada vez mais frequente entre os portugueses, contudo a credibilidade das fontes disponíveis é a principal preocupação associada a este tipo de pesquisas. Para além dos ... -
Pesquisa Interactiva de Fotografias com Base na Regra dos Terços
(The Eurographics Association, 2021)Hoje em dia, geramos uma quantidade cada vez maior de fotografias digitais. Estas encontram-se, frequentemente, desorganizadas ou organizadas em hierarquias complexas. A pesquisa por determinadas imagens específicas torna-se, ... -
Pesquisas Baseadas na Localização e na Orientação em Dispositivos Móveis
(The Eurographics Association, 2021)A crescente utilizar;ao de dispositivos m6veis e a sua evolur;ao, corn o surgimento de modelos equipados corn cdmara digital e sensores de posir;ao e direcr;ao, propiciam o desenvolvimento de novas formas de interacr;ao e ... -
Phase Space Data-Driven Simulation of Elastic Materials
(The Eurographics Association, 2016)The use of data driven models in computer animation offers several benefits. We present an analysis of a regression model as a method to simulate cloth. In our approach, we generate data from a simple mass-spring system ... -
Physical and Perceptual Limitations of a Projector-based High Dynamic Range Display
(The Eurographics Association, 2012)High dynamic range (HDR) displays capable of reproducing scenes of high luminance (exceeding 2,000 cd/m2) and contrast (more than 10,000:1) are a useful tool for research on visual performance, image quality or colour ... -
A Physical Model for the Polarized Scattering of Light
(The Eurographics Association, 2008)The change in polarization state due to the interaction of light with the surface and beneath the surface of an object has become increasingly important in realistic image synthesis of materials such as metallic, iridescent ... -
Physically Based Simulation and Visualization of Fire in Real-Time using the GPU
(The Eurographics Association, 2006)In this paper we present a physically based framework for real-time simulation and visualization of fire using the GPU. The physics of fire is modeled through a combination of a fluid solver and a combustion process causing ... -
Physically Based Skeleton Tracking
(The Eurographics Association, 2017)Skeleton tracking has multiple applications such as games, virtual reality, motion capture and more. One of the main challenges of pose detection is to be able to obtain the best possible quality with a cheap and easy-to-use ... -
