Abordagem Tridimensional e Interactiva para Analisador Táctico de Match Racing
(The Eurographics Association, 2021)Tem havido, recentemente, uma ascensão tecnológica no contexto desportivo. É cada vez mais recorrente, em diversas modalidades, o uso de sistemas audiovisuais, comunicação e gestão de dados, entre outros. Neste artigo é ... -
Above and Beyond: Outer Space as a Metaphor for Document Browsing and Visualization
(The Eurographics Association, 2021)Currently, any ordinary user has hundreds or even thousands of electronic documents stored on his computer. Usually, those documents are archived using an hierarchically-organized file system, making their retrieval at a ... -
Accelerating Raycasting Utilizing Volume Segmentation of Industrial CT Data
(The Eurographics Association, 2009)We propose a flexible acceleration technique for raycasting targeted at industrial CT data and the context of material deficiency checking. Utilizing volume segmentation that is typically employed for object analysis, GPU ... -
Accelerating Surface Tension Calculation in SPH via Particle Classification and Monte Carlo Integration
(The Eurographics Association, 2019)Surface tension has a strong influence on the shape of fluid interfaces. We propose a method to calculate the corresponding forces efficiently. In contrast to several previous approaches, we discriminate to this end between ... -
Accurate and Marker-less Head Tracking Using Depth Sensors
(The Eurographics Association, 2013)Parameterized, high-fidelity 3D surface models can not only be used for rendering animations in the context of Computer Graphics (CG), but have become increasingly popular for analyzing data, and thus making these accessible ... -
Accurate Molecular Atom Selection in VR
(The Eurographics Association, 2022)Target acquisition is a basic task that is part of almost any high-level interaction in 3D environments. Therefore, providing accurate selection is a necessity for most applications and games. When targets are small and ... -
