Large Scale Pedestrian Multi-Simulation for a Decision Support Tool
(The Eurographics Association, 2012)Ability to simulate pedestrian behaviour on a large scale is essential in identifying potential dangers in public spaces during an evacuation. Multiple designs must be tested with varying parameters and run multiple times ... -
A Lemon is not a Monstar: Visualization of Singularities of Symmetric Second Rank Tensor Fields in the Plane
(The Eurographics Association, 2008)In the visualization of the topology of second rank symmetric tensor fields in the plane one can extract some key points (degenerate points), and curves (separatrices) that characterize the qualitative behaviour of the ... -
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 ... -
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 ... -
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] -
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, ... -
Low Cost Decomposition of Direct and Global Illumination in Real Scenes
(The Eurographics Association, 2015)Recent advances in the field of computational light transport have made it possible to solve previously unsolvable problems thanks to incorporating new devices and techniques. One of these problems is the decomposition of ... -
Low Cost Finger Tracking on Flat Surfaces
(The Eurographics Association, 2008)We present a flexible system to track the movements of a bare finger on a flat surface. The proposed system is able to discriminate whether the user is touching or just pointing at the surface. The system works using two ... -
Low Cost Handheld 3D Scanning for Architectural Elements Acquisition
(The Eurographics Association, 2016)3D scanning has gone a long way since its first appearance in cultural heritage digitization and modeling. In the recent years some new low cost, fast, accurate emerging technologies are flooding the market. Envisioning ... -
Low Cost Recovery of Spectral Power Distributions
(The Eurographics Association, 2014)Measuring the spectral power distribution of a light source, that is, the emission as a function of wavelength, typically requires the use of spectrophotometers or multispectral cameras. Here, we propose a low-cost system ... -
Low-cost Experimental Setups for Mid-air 3D Reconstruction
(The Eurographics Association, 2015)The reconstruction of the physical environment using a depth sensor involves data-intensive computations which are difficult to implement on mobile systems (e.g., tracking and aligning the position of the sensor with the ... -
A Low-Cost Single-Pixel Thermographic Camera
(The Eurographics Association, 2011)A working prototype of single-pixel thermographic camera which can be built for 100 Euros is presented. It is based on a pyrometer's sensor (thermopile with optics) and two mirrors mounted on servos to scan horizontally ... -
Magic in Augmented Reality
