LeoMCAD: A Lego-based Mechanical CAD system
(The Eurographics Association, 2018)Mechanical Design (MCAD) tools are used for creating 3D digital prototypes used in the design, visualization, and simulation of products. In this paper we present LeoMCAD, a Lego-based mechanical system designed to be used ... -
Less is more: Focused Design and Problem Framing in Visualisation - Developing the ColloCaid Collocation Editor
(The Eurographics Association, 2023)One of the challenges when developing a visualisation tool, especially at the start of a research project, is to amalgamate numerous requirements and various possibilities and decide what to create. With software development, ... -
Level of Detail for Physically Based Fire
(The Eurographics Association, 2007)In this paper, we propose a framework for implementing level of detail for a physically based fire rendering running on the GPU. The physics of the fire is simulated using a fluid solver and combustion modelling, and the ... -
A Level-of-Detail Technique for Urban Physics Calculations in Large Urban Environments
(The Eurographics Association, 2019)In many applications, such as urban physics simulations or the study of the solar impact effects at different scales, complex 3D city models are required to evaluate physical values. In this paper we present a new technique ... -
Leveraging Moving Parameterization and Adaptive THB-Splines for CAD Surface Reconstruction of Aircraft Engine Components
(The Eurographics Association, 2023)Reconstruction of highly accurate CAD models from point clouds is both paramount and challenging in industries such as aviation. Due to the acquisition process, this kind of data can be scattered and affected by noise, yet ... -
Licenciatura em Comunicações e Multimédia
(The Eurographics Association, 2023)This document describes the Multimedia and Communications Degree (Licenciatura em Comunicações e Multi- média, LCM) of the Faculty of Science and Technology of the University of Coimbra. The LCM degree was approved in 2002 ... -
Licenciatura em Tecnologias de Informação Visual
(The Eurographics Association, 2023)Face às exigências da nova sociedade da informação, onde o pensamento visual e a expressão através de diferentes suportes visuais são hoje competências básicas para a utilização produtiva de todos os recursos que as novas ... -
Light Clustering for Dynamic Image Based Lighting
(The Eurographics Association, 2012)High Dynamic Range (HDR) imagery has made it possible to relight virtual objects accurately with the captured lighting. This technique, called Image Based Lighting (IBL), is a commonly used to render scenes using real-world ... -
Light Field Rendering for Games
(The Eurographics Association, 2008)This paper studies the problem of integrating high-quality light field rendering into state-of-the-art real-time computer games. We present a complete production pipeline for generation of light fields from arbitrary complex ... -
Light Source Detection in Photographs
(The Eurographics Association, 2009)Common tasks related to image processing or augmented reality include rendering new objects into existing images, or matching objects with unknown illumination. To facilitate such algorithms, it is often necessary to infer ... -
Lineal Hull: Two Algorithms for Convex Hull
(The Eurographics Association, 2012)This poster proposes a concept that improves the existing algorithms for convex hull. This concept can be applied whether the initial points are sorted or not. The results show a comparation with Quick-Hull (QH) [BDH96] -
Linear Solvers for Stable Fluids: GPU vs CPU
(The Eurographics Association, 2021)Fluid simulation has been an active research field in computer graphics for the last 30 years. Stam's stable fluids method, among others, is used for solving equations that govern fluids. This method solves a sparse linear ... -
Linear-Time Dynamics of Characters with Stiff Joints
(The Eurographics Association, 2021)Characters, like other articulated objects and structures, are typically simulated using articulated dynamics algorithms. There are efficient linear-time algorithms for the simulation of open-chain articulated bodies, but ... -
Literacia em Informação: Novos Desafios à Computação Gráfica e Multimédia
(The Eurographics Association, 2023)A Literacia em Informação (LI) (Information Literacy) entendida como a capacidade para pesquisar, analisar, produzir e avaliar informação – é presentemente reconhecida como uma competência essencial para a educa- ção, no ... -
Localised Topology Correction for Hypertextured Terrains
(The Eurographics Association, 2008)Terrains for computer graphics have traditionally been modelled with height fields. In the case of procedurally defined terrains, the height field is generated by a displacement map z -
Locally-Adaptive Texture Compression
(The Eurographics Association, 2009)Current schemes for texture compression fail to exploit spatial coherence in an adaptive manner due to the strict efficiency constraints imposed by GPU-based, fragment-level decompression. In this paper we present a texture ... -
Locating Companies in 3D Urban Environments on the Internet
(The Eurographics Association, 2012)3D visualization is being incorporated in a lot of fields, including Geographic Information Systems (GIS). In addition, the Internet is the most popular method to find information, due to its accessibility. For this reason, ... -
