Automating Transfer Function Design for Volume Rendering Using Hierarchical Clustering of Material Boundaries
(The Eurographics Association, 2006)Transfer function design plays a crucial role in direct volume rendering. Furthermore, it has a major influence on the efficiency of the visualization process. We have developed a framework that facilitates the semi-automatic ... -
Automating Transfer Function Design with Valley Cell-Based Clustering of 2D Density Plots
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Two-dimensional transfer functions are an effective and well-accepted tool in volume classification. The design of them mostly depends on the user's experience and thus remains a challenge. Therefore, we present an approach ... -
Automating Visualization Quality Assessment: a Case Study in Higher Education
(The Eurographics Association, 2021)We present a case study in the use of machine+human mixed intelligence for visualization quality assessment, applying automated visualization quality metrics to support the human assessment of data visualizations produced ... -
Automation for camera-only 6D object detection
(2021-04-21)Today a widespread deployment of Augmented Reality (AR) systems is only possible by means of computer vision frameworks like ARKit and ARCore, which abstract from specific devices, yet restrict the set of devices to the ... -
Automation in Multi-Image Spherical Photogrammetry for 3D Architectural Reconstructions
(The Eurographics Association, 2010)The derivation of 3D metric information from spherical images for interactive exploration and realistic 3D modeling is receiving great attention due to their high-resolution content, large field-of-view, lowcost, easiness, ... -
Automotive Soiling Simulation Based On Massive Particle Tracing
(The Eurographics Association, 2001)In the automotive industry Lattice-Boltzmann type flow solvers like PowerFlow from Exa Corporation are becoming increasingly important. In contrast to the traditional finite volume approach PowerFlow utilizes a hierachical ... -
Autonomous Behaviors for Interactive Vehicle Animations
(The Eurographics Association, 2004)We present a method for synthesizing animations of autonomous space, water, and land-based vehicles in games or other interactive simulations. Controlling the motion of such vehicles to achieve a desirable behavior is ... -
Autonomous Particles for In-Situ-Friendly Flow Map Sampling
(The Eurographics Association, 2023)Computing and storing flow maps is a common approach to processing and analyzing large flow simulations in a Lagrangian way. Accurate Lagrangian-based visualizations require a good sampling of the flow map. We present an ... -
Autonomous Particles for Interactive Flow Visualization
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)We present an interactive approach to analyse flow fields using a new type of particle system, which is composed of autonomous particles exploring the flow. While particles provide a very intuitive way to visualize flows, ... -
Autonomous Pedestrians
(The Eurographics Association, 2005)We address the difficult open problem of emulating the rich complexity of real pedestrians in urban environments. Our artificial life approach integrates motor, perceptual, behavioral, and cognitive components within a ... -
Autoria de Courseware para Ambientes Distribuídos
(The Eurographics Association, 2023)Esta comunicação apresenta um novo conceito para a concepção e distribuição de courseware. O novo conceito baseia-se nos princípios da modularidade e adaptabilidade, permite custos inferiores de produção de courseware e ... -
Autostereoscopic Rendering of Multiple Light Fields
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Light fields were introduced a decade ago as a new high-dimensional graphics rendering model. However, they have not been thoroughly used because their applications are very specific and their storage requirements are too ... -
AutoStyle: Automatic Style Transfer from Image Collections to Users' Images
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Stylizing photos, to give them an antique or artistic look, has become popular in recent years. The available stylization filters, however, are usually created manually by artists, resulting in a narrow set of choices. ... -
AUV Planning, An application for AUV mission planning
(The Eurographics Association, 2021)Veículos autónomos submarinos (Autonomous underwater vehicles - AUV), são veículos controlados por computador que operam de forma autónoma em ambientes submarinos. A inacessibilidade que resulta de operar a grandes ... -
Auxiliary Features‐Guided Super Resolution for Monte Carlo Rendering
(© 2024 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2024)This paper investigates super‐resolution to reduce the number of pixels to render and thus speed up Monte Carlo rendering algorithms. While great progress has been made to super‐resolution technologies, it is essentially ... -
Avaliação Comparativa da Usabilidade de Locais na World-Wide-Web
