Interfaces caligráficas RISC
(The Eurographics Association, 2022)
Ao aumento do poder de cálculo das plataformas computacionais na última década não têm correspondido ganhos de usabilidade dos programas de desenho assistido por computador, pese embora o sucesso das chamadas interfaces ...
Jogo do Galo, Agente de Apoio à Utilização de Jogos por Deficientes Profundos
(The Eurographics Association, 2022)
O projecto apresentado nesta comunicação teve por objectivo realizar e testar um agente autónomo para apoio à utilização de jogos por deficientes profundos. O agente desenvolvido tem como primeiro objectivo a parcial ...
Visualização interactiva tridimensional em Java3D
(The Eurographics Association, 2022)
Esta comunicação descreve a concepção e realização em Java/Java3D da aplicação NISVAS para visualização interactiva de conjuntos de dados de grande volume resultantes da simulação numérica de fenómenos complexos. A aplicação, ...
Jogos de Guerra e Paz
(The Eurographics Association, 2022)
A simulação de ambientes virtuais realistas de grande complexidade e interactividade é um problema complexo a vários níveis. Na parte de visualização as dificuldades prendem-se com as limitações do hardware para apresentar ...
Towards Content-Based Retrieval of Technical Orawings through High-Oimensional lndexing
(The Eurographics Association, 2022)
This paper presents a new approach to classify, index and retrieve technical drawings by content. Our work uses spatial relationships, visual elements and high-dimensional indexing mechanisms to retrieve complex drawings ...
Simulating E-Garments Oressed on Personalísed Avatars
(The Eurographics Association, 2022)
We present a general computational architecture that solves the problem of the production of physical-based virtual textiles and garments (so called electronic garments or e-garments), applicable in lnternet-based ...
Virtual Reality in Cooperative Teleoperation
(The Eurographics Association, 2022)
Virtual reality enables to build systems that enhance communication by facilitating information display. ln teleoperation applications, virtual reality improves task performance thanks to intuitive manipulation and exploration ...
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 ...
Oetermining orientation of Laser scanned surfaces
(The Eurographics Association, 2022)
Real 3D data acquired from scanning technology provide interesting 3D models for research and industrial applications. However before these models can be used, a surface needs to be jitted to a point cloud of an unknown ...
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 ...
