Using Spatial Augmented Reality to Increase Perceived Translucency of Real 3D Objects
(The Eurographics Association, 2023)Translucency is an important optical and perceptual attribute that has a significant impact on the appearance of objects and materials. Expensive and time-consuming manufacturing process is required to produce a translucent ... -
Using Subdivision on Hierarchical Data to Reconstruct Radiosity Distribution
(Blackwell Publishers Ltd and the Eurographics Association, 1997)Computing global illumination by finite element techniques usually generates a piecewise constant approximation of the radiosity distribution on surfaces. Directly displaying such scenes generates artefacts due to ... -
Using Teleporting, Awareness and Multiple Views to Improve Teamwork in Collaborative Virtual Environments
(The Eurographics Association, 2008)Mobile Group Dynamics (MGDs) are a suite of techniques that help people work together in large-scale col- laborative virtual environments (CVEs). The present paper describes the implementation and evaluation of three ... -
Using temporal and spatial coherence for accelerating the calculation of animation sequences
(Eurographics Association, 1991)Ray tracing is a well known technique for generating realistic images. One of the major drawbacks of this approach are the extensive computational requirements for image calculation. When generating animation sequences ... -
Using The Barnes-Hut Approximation for Fast N-Body Simulations in Computer Graphics
(The Eurographics Association, 2023)Particle systems in CG often encounter performance issues when all the particles rely on mutual influence, producing an O(N2) performance. The Barnes-Hut approximation is used in the field of astrophysics to provide ... -
Using the Discrete Fourier Transform for Character Motion Blending and Manipulation - a Streamlined Approach
(The Eurographics Association, 2010)Motion capture data allows natural-looking motion to be bestowed upon simulated characters. Research has sought ways of extending the range of motions it can reproduce. One such method involves blending between captured ... -
Using Time-of-Flight Range Data for Occlusion Handling in Augmented Reality
(The Eurographics Association, 2007)One of the main problems of monoscopic video see-through augmented reality (AR) is the lack of reliable depth information. This makes it difficult to correctly represent complex spatial interactions between real and virtual ... -
Using User-Centered Techniques for the Design and Evaluation of Interactive Visualizations to Support Urban and Regional Planning: Case Study Bogota 21
(The Eurographics Association, 2013)User-centered techniques and evaluations are very important for the design of interactive visualizations. We applied the UCIV4 Planning Approach (User-Centered Interactive Visualizations for Planning) within the project ... -
Using VisTrails and Provenance for Teaching Scientific Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Over the last 20 years, visualization courses have been developed and offered at universities around the world. Many of these courses use established visualization libraries and tools (e.g. VTK, ParaView, AVS, VisIt) as a ... -

Using Visualisation Techniques and Molecular Dynamics to Study Atoms Diffusing in Glass
(The Eurographics Association, 2011)In this poster, virtual reality and visualisation techniques are used to interpret the output of Molecular Dynamics simulations. In particular, mixtures of sodium-disilicate and potassium-silicate are studied. In such ... -
Using Visualization to Explore Original and Anonymized LBSN Data
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present GSUVis, a visualization tool designed to provide better understanding of location-based social network (LBSN) data. LBSN data is one of the most important sources of information for transportation, marketing, ... -
Using VTK as a Tool for Teaching and Applying Computer Graphics
(The Eurographics Association, 2006)During the first semester of 2005/2006 we used the Visualization Toolkit (VTK) as a tool for teaching and applying Computer Graphics, both for Computer Engineering students who chose to attend the 3D Modeling and Visualization ... -
Using Vulkan for Graphics Research
(The Eurographics Association, 2023)The Vulkan API has has been released in 2016 and it has continued to evolve to include the latest hardware capabilities. Compared to OpenGL, it is a more verbose API that requires a deeper knowledge of the underlying ... -
Using Wavefront Tracing for the Visualization and Optimization of Progressive Lenses
(Blackwell Publishers Ltd and the Eurographics Association, 1998)Progressive addition lenses are a relatively new approach to compensate for defects of the human visual system. While traditional spectacles use rotationally symmetric lenses, progressive lenses require the specification ... -
Using Webcams for Product Presentations in HTML5
(The Eurographics Association, 2013)The Media Capture and Streams API ("getUserMedia API") enables plug-in free webcam support in HTML5. This opens new ways of interacting with visualisations using open web standards. In this work, two techniques are proposed ... -
USTNet: Unsupervised Shape-to-Shape Translation via Disentangled Representations
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We propose USTNet, a novel deep learning approach designed for learning shape-to-shape translation from unpaired domains in an unsupervised manner. The core of our approach lies in disentangled representation learning that ... -
Utilização de Dados Fisiológicos na Avaliação de Aplicações Móveis
