Challenges for modern Scene-Graph Systems
(The Eurographics Association, 2007)Current scenegraph systems, especially systems used to build general purpose virtual reality systems, are trailing game engines and similar specialized systems in terms of the adaption of new renderingmethods like the ... -
Characterisation of Position Based Dynamics for Elastic Materials
(The Eurographics Association, 2016)Position Based Dynamics (PBD) methodology is a widely used approach for simulation of deformable bodies in the context of video games. Its main advantages over force based methods are its unconditional stability and its ... -
Chladni Plate Visualisation
(The Eurographics Association, 2022)The creation of images made out of sound is an ancient discovery from many civilisations, called Cymatics. Cymatics can be referred to as the science of visualising audio frequencies through the Chladni plate. Over the ... -
CHROMAGRAM: A Real-time Chroma Key Application for Mobile Devices
(The Eurographics Association, 2014)Chroma Key is a special-effects technique widely used by television and motion picture industries for image composition. This technique allows users to replace sections identified by a chosen colour in a multimedia stream ... -
Classifying User Interface Accessibility for Colourblind Users
(The Eurographics Association, 2023)Colour vision deficiency (CVD, colourblindness) is the failure or decreased ability to distinguish between certain colours even under normal lighting conditions. There are an estimated 300 million people worldwide with ... -
CLAWS: Computational Load Balancing for Accelerated Neighbor Processing on GPUs using Warp Scheduling
(The Eurographics Association, 2020)Nearest neighbor search algorithms on GPUs have been improving for years. Starting with tree-based approaches in the middle 70's, state-of-the-art methods use hash-based or grid-based methods. Leveraging high-performance ... -
Click and Brush: A Novel Way of Finding Correlations and Relationships in Visualizations
(The Eurographics Association, 2005)Brushing is a commonly used interaction technique that allows users to select items or an area of the visualization as the user moves the mouse. Brushing is often used with multiple views, where any co-related information ... -
CLIKSA - An Application for Physics Education in Secondary School
(The Eurographics Association, 2014)In this paper we present an application for teaching Physics courses in secondary education. It is a web application, based on HTML5 and on JavaScript. We rely on the graphical capabilities of this technology, including ... -
ClimbOn – An infinite game with difficulty adjustment
(The Eurographics Association, 2021)This document describes an infinite game called ClimbOn. The game concept is fairly simple and aims to be suitable for casual gamers that play for short periods, wanting an instant action system with direct and short ... -
Coastal Shelf Visualization using VTK and OpenDX of Hydro-Informatic Numerical Models
(The Eurographics Association, 2009)Scientific visualization has an important role in climate change analysis, especially by creating dynamic interactive environments. The earth sciences, such as oceanography, utilize many numerical models; experts wish to ... -
Coded Apertures for Defocus Deblurring
(The Eurographics Association, 2021)The field of computational photography, and in particular the design and implementation of coded apertures, has yielded impressive results in the last years. Among their applications lies defocus deblurring, in which we ... -
Cognimobile: Diferenças Cognitivas e os Dispositivos Móveis
(The Eurographics Association, 2021)Embora dispositivos como os telemóveis assumam um papel cada vez mais importante na vida diária de muitas pessoas, estes continuam a apresentar dificuldades e restrições a populações com necessidades especiais. Os cegos e ... -
Cognitive walkthroughs in the evaluation of user interfaces for children
(The Eurographics Association, 2021)This paper describes a case-study, dealing with the application of the cognitive walkthrough as a method of evaluating an interface built for children. We performed the walkthrough and tested the interface with children ... -
COGNITO – Captura, reconhecimento e visualização de atividades manuais complexas
(The Eurographics Association, 2021)Neste artigo curto apresenta-se um sistema capaz de automaticamente capturar, reconhecer e visualizar atividades motoras humanas, em diferentes contextos, mas com aplicação prática, por exemplo, na implementação de manuais ... -
Coherent Hierarchical Level-of-Detail (HLOD) Refinement Through Hardware Occlusion Queries
(The Eurographics Association, 2006)We present a coherent hierarchical level of detail (HLOD) culling algorithm that employs a novel metric to perform the refinement of a HLOD-based system that takes into account visibility information. The information is ... -
Collaborative Computational Projects - Visualisation Applications Survey
(The Eurographics Association, 2016)This extended abstract presents initial outcomes from three visualisation user needs surveys, and includes an invitation for new communities to engage with follow-on surveys. Statistical and text cluster analysis have been ... -
