More Stable SPH-based Fluid Simulation
(The Eurographics Association, 2012)
The simulation of fluid is a field largely discussed, from the viewpoint of engineering, in the so-called computational fluid dynamics (CFD). A problem that occurs repeatedly in the literature of CFD is the stability of ...
Computing Curvature Information on 3D Meshes from Cultural Heritage Artifacts
(The Eurographics Association, 2012)
The curvature provides essential information about the features of a object surface. This poster presents an operation that makes it possible to generate the curvature information in the CHiSEL system.
Modelling of Clouds from a Hemispherical Image
(The Eurographics Association, 2014)
This paper presents an image-based method for modelling clouds. Unlike previous image-based approaches, a hemispherical photograph is used as input, enabling to consider an entire sky instead of merely a portion. Our method ...
Topological Visualisation Techniques for the Understanding of Lattice Quantum Chromodynamics (LQCD) Simulations
(The Eurographics Association, 2016)
The use of topology for visualisation applications has become increasingly popular due to its ability to summarise data at a high level. Criticalities in scalar field data are used by visualisation methods such as the Reeb ...
Tactile Mesh Saliency: A Brief Synopsis
(The Eurographics Association, 2016)
This work has previously been published [LDS 16] and this extended abstract provides a synopsis for further discussion at the UK CGVC 2016 conference. We introduce the concept of tactile mesh saliency, where tactile salient ...
Using Semi-automatic 3D Scene Reconstruction to Create a Digital Medieval Charnel Chapel
(The Eurographics Association, 2016)
The use of a terrestrial laser scanner (TLS) has become a popular technique for the acquisition of 3D scenes in the fields of cultural heritage and archaeology. In this study, a semi-automatic reconstruction technique is ...
Volumetric Spot Noise for Procedural 3D Shell Texture Synthesis
(The Eurographics Association, 2016)
In this paper, we present an extension of the Locally Controlled Spot Noise and a visualization pipeline for volumetric fuzzy details synthesis. We extend the noise model to author volumetric fuzzy details using filtered ...
Real-Time Modelling and Rendering of Sprayed Concrete
(The Eurographics Association, 2021)
This paper presents a new real-time method to model and render how sprayed concrete is spread on a surface. The method not only models and renders deposits sprayed from any angle, any distance and with any concrete flow, ...
A Simple Surface Tracking Method for Physically-Based 3D Water Simulations
(The Eurographics Association, 2021)
Water simulation, and more generically fluid simulation, is an important research topic in computer graphics. In 3D Eulerian Navier-Stokes-based water simulations, surface tracking and rendering are two delicate problems. ...
ERAS - An Ontology-Based Tool for Expeditious Reconstruction of Virtual Cultural Heritage Sites
(The Eurographics Association, 2021)
Nos últimos anos, vários investigadores têm proposto métodos semiautomáticos para a geração expedita de modelos virtuais de edifícios e até cidades, em alguns casos direcionados à reconstrução do património cultural. No ...
