HaloDot: Visualization of the Relevance of Off-Screen Objects
(The Eurographics Association, 2021)The increasing usage of maps on mobile devices reinforce the need to solve some visualization and usability issues that constraint the user's interaction with information visualization applications. When exploring map ... -
Hand Made 3d Modelling for the Reconstructive Study of Temple C in Selinunte : Preliminary Results
(The Eurographics Association, 2006)This paper illustrates the preliminary results of the virtual reconstruction of temple C in Selinunte. The reconstruction was undertaken as part of the Land-Lab Project launched by the University of Lecce in 2003 for the ... -
Hand Motion Capture and Tracking in 3D Animation
(The Eurographics Association, 2006)This extended abstract details previous methods for motion tracking and capture in 3D animation and in particular that of hand motion tracking and capture. Our research aims to enable gesture capture with interpretation ... -
A Haptic Rendering Algorithm for Drilling into Volume Data
(The Eurographics Association, 2008)With the developments of volume visualisation technology for complex data sets comes new challenges in terms of user interaction and information extraction. Volume haptics has proven itself to be an effective way of ... -
A Haptic System for Drilling into Volume Data with Polygonal Tools
(The Eurographics Association, 2009)With the developments of volume visualization technology for complex data sets comes new challenges in terms of user interaction and information extraction. Volume haptics has proven itself to be an effective way of ... -
Hardware Accelerated Medical Data Visualisation on the Web
(The Eurographics Association, 2012)This paper proposes a way to develop high-quality real-time web-based medical 3D data visualisation. Isosurface extraction is used as an example to discuss how to use programmable Graphics Processing Units (GPUs) and shaders ... -
Hardware Accelerated Shaders Using FPGAs
(The Eurographics Association, 2009)We demonstrate that Field Programable Gate Arrays (FPGAs) can be used to accelerate shading of surfaces for production quality rendering (a task standard interactive graphics hardware is generally ill-suited to) by allowing ... -
Hardware de Visualização orientado para X Windows
(The Eurographics Association, 2023)O "X Window System" é um dos vários sistemas de gestão de janelas disponíveis actualmente, tendo a seu favor o facto de ser suportado por um instituto de renome mundial (MIT) e por alguns fabricantes de primeiro plano (DEC, ... -
Hash-based Hierarchical Caching for Interactive Previews in Global Illumination Rendering
(The Eurographics Association, 2019)Modern Monte-Carlo-based rendering systems still suffer from the computational complexity involved in the generation of noise-free images, making it challenging to synthesize interactive previews. We present a framework ... -
Heat Flow Based Relaxation of n Dimensional Discrete Hyper Surfaces
(The Eurographics Association, 2017)We consider the problem of relaxing a discrete (n - 1) dimensional hyper surface defining the boundary between two adjacent n dimensional regions in a discrete segmentation. This problem often occurs in computer graphics ... -
Herramientas para la Triangulación y Registrado Inicial de Modelos 3D a Partir de Nubes de Puntos
(The Eurographics Association, 2008)Presentamos un sistema para el tratamiento de datos adquiridos mediante escáner láser 3D, cuyo objetivo es la obtención de modelos tridimensionales de manera semiautomática. El sistema, que preserva el histórico de operaciones ... -
A High Quality 3D Controller for Mobile and Desktop Web Applications
(The Eurographics Association, 2021)The interaction between a 2D input device (like a mouse or a touchscreen) and a 3D object on the screen with the purpose of examining it in detail is a well-studied interaction problem. The inherent difference in degrees ... -
High Resolution Medical 3D Data Sets on Mobile Devices and WebGL
(The Eurographics Association, 2012)Nowadays, mobile devices and the web are being used to deliver 3D graphics to mass users. However, applications such as visualization of high resolution medical models are still impossible to handle in such platforms due ... -
High-quality Compression of Mipmapped Textures
(The Eurographics Association, 2021)High-quality texture minification techniques, including trilinear and anisotropic filtering, require texture data to be arranged into a collection of prefiltered texture maps called mipmaps. In this paper we present a ... -
Higher Dimensional Vector Field Visualization: A Survey
(The Eurographics Association, 2009)Vector field visualization research has evolved very rapidly over the last two decades. There is growing consensus amongst the research community that the challenge of two-dimensional vector field visualization is virtually ... -
HIJSON: Cartographic Document for Web Modeling of Interactive Indoor Mapping
(The Eurographics Association, 2015)This paper introduces HIJSON, a novel indoor cartographic document format with several enhancements. The document is generated using LAR (Linear Algebraic Representation), so allowing for cellular complexes with general ... -
