PRODUCT LIFECYCLE DATA SHARING AND VISUALISATION: WEB-BASED APPROACHES
Both product design and manufacturing are intrinsically collaborative processes. From conception and design to project completion and ongoing maintenance, all points in the lifecycle of any product involve the work of fluctuating teams of designers, suppliers and customers. That is why companies are involved in the creation of a distributed design and a manufacturing environment which could provide an effective way to communicate and share information throughout the entire enterprise and the supply chain. At present, the technologies that support such a strategy are based on World Wide Web platforms and follow two different paths. The first one focuses on 2D documentation improvement and introduces 3D interactive information in order to add knowledge to drawings. The second one works directly on 3D models and tries to extend the life of 3D data moving these design information downstream through the entire product lifecycle. Unfortunately the actual lack of a unique 3D Web-based standard has stimulated the growing up of many different proprietary and open source standards and, as a consequence, a production of an incompatible information exchange over the WEB. This paper proposes a structured analysis of Web-based solutions, trying to identify the most critical aspects to promote a unique 3D digital standard model capable of sharing product and manufacturing data more effectivelyâregardless of geographic boundaries, data structures, processes or computing environmen
Reanimating cultural heritage through digital technologies
Digital technologies are becoming extremely important for web-based cultural heritage applications. This thesis presents novel digital technology solutions to 'access and interact' with digital heritage objects and collections. These innovative solutions utilize service orientation (web services), workflows, and social networking and Web 2.0 mashup technologies to innovate the creation, interpretation and use of collections dispersed in a global museumscape, where community participation is achieved through social networking.
These solutions are embedded in a novel concept called Digital Library Services for Playing with Shared Heritage (DISPLAYS). DISPLAYS is concerned with creating tools and services to implement a digital library system, which allows the heritage community and museum professionals alike to create, interpret and use digital heritage content in visualization and interaction environments using web technologies based on social networking. In particular, this thesis presents a specific implementation of DISPLAYS called the Reanimating Cultural Heritage system, which is modelled on the five main functionalities or services defined in the DISPLAYS architecture, content creation, archival, exposition, presentation and interaction, for handling digital heritage objects.
The main focus of this thesis is the design of the Reanimating Cultural Heritage system's social networking functionality that provides an innovative solution for integrating community access and interaction with the Sierra Leone digital heritage repository composed of collections from the British Museum, Glasgow Museums and Brighton Museum and Art Gallery. The novel use of Web 2.0 mashups in this digital heritage repository also allows the seamless integration of these museum collections to be merged with user or community generated content, while preserving the quality of museum collections data.
Finally, this thesis tests and evaluates the usability of the Reanimating Cultural Heritage social networking system, in particular the suitability of the digital technology solution deployed. Testing is performed with a user group composed of several users, and the results obtained are presented
Share - Publish - Store - Preserve. Methodologies, Tools and Challenges for 3D Use in Social Sciences and Humanities
Through this White Paper, which gathers contributions from experts of 3D data as well as professionals concerned with the interoperability and sustainability of 3D research data, the PARTHENOS project aims at highlighting some of the current issues they have to face, with possible specific points according to the discipline, and potential practices and methodologies to deal with these issues. During the workshop, several tools to deal with these issues have been introduced and confronted with the participants experiences, this White Paper now intends to go further by also integrating participants feedbacks and suggestions of potential improvements. Therefore, even if the focus is put on specific tools, the main goal is to contribute to the development of standardized good practices related to the sharing, publication, storage and long-term preservation of 3D data
A WebGL application based on BIM IFC
Dissertação apresentada à Universidade Fernando Pessoa como partes dos requisitos para a obtenção do grau de Mestre em Engenharia Informåtica, ramo de Computação MóvelThe possibility of displaying high performance 3D accelerated graphics in the browser
is seen as an obstacle to the conversion of applications to the web. The release of
WebGL made Web3D gain new strength to overcome that obstacle. Architecture,
Engineering and Construction (AEC) tools are a type of applications that could benefit
with this advance. In the AEC industry, there is a standard candidate for Building
Information Modelling (BIM), called Industry Foundation Classes (IFC). This data
model promotes interoperability between AEC tools, giving a common format to the
applications.
This work comes from the need of redesigning a legacy application that allows the user
to design, display and calculate building structures. Focusing on the displaying of
building structures, this work merges IFC and WebGL into an application, to replicate in
a modern way the legacy application capabilities.
This is done by developing a server module that processes the IFC data model and a
client module that displays that model in a WebGL environment.
The result is a prototype web application capable of displaying 3D IFC building models
in the browser without plug-ins. A possibilidade de visualização de gråficos acelerados 3D de alto desempenho no
navegador ainda é visto como um obståculo na migração de aplicaçÔes para a web. O
lançamento do WebGL fez o Web3D ganhar uma nova força para superar esse obståculo.
As ferramentas de Arquitetura, Engenharia e Construção (AEC) são um tipo de
aplicaçÔes que podem beneficiar com este avanço. Na indĂșstria AEC, hĂĄ um candidato a
padrĂŁo para Building Information Modelling (BIM), chamado de Industry Foundation
Classes (IFC). Este modelo de dados promove a interoperabilidade entre as ferramentas
de AEC, fornecendo um formato comum às aplicaçÔes.
Este trabalho surge da necessidade de redesenhar uma aplicação legada que permite ao
o utilizador projetar, visualizar e calcular estruturas de edifĂcios. Focando na
visualização de estruturas de edifĂcios, este trabalho funde o IFC e o WebGL numa
aplicação, para replicar de forma moderna as capacidades da aplicação legada.
Isto é feito através do desenvolvimento de um módulo de servidor que processa o
modelo de dados IFC e um mĂłdulo de cliente que mostra esse modelo num ambiente
WebGL.
O resultado é um protótipo duma aplicação web capaz de visualizar modelos 3D de
edifĂcios em formato IFC no browser sem plug-ins
Analysis of Visualisation and Interaction Tools Authors
This document provides an in-depth analysis of visualization and interaction tools employed in the context of Virtual Museum. This analysis is required to identify and design the tools and the different components that will be part of the Common Implementation Framework (CIF). The CIF will be the base of the web-based services and tools to support the development of Virtual Museums with particular attention to online Virtual Museum.The main goal is to provide to the stakeholders and developers an useful platform to support and help them in the development of their projects, despite the nature of the project itself. The design of the Common Implementation Framework (CIF) is based on an analysis of the typical workflow ofthe V-MUST partners and their perceived limitations of current technologies. This document is based also on the results of the V-MUST technical questionnaire (presented in the Deliverable 4.1). Based on these two source of information, we have selected some important tools (mainly visualization tools) and services and we elaborate some first guidelines and ideas for the design and development of the CIF, that shall provide a technological foundation for the V-MUST Platform, together with the V-MUST repository/repositories and the additional services defined in the WP4. Two state of the art reports, one about user interface design and another one about visualization technologies have been also provided in this document
Three-dimensional interactive model of lumbar spinal structures
The application of three-dimensional software to pre-operative magnĂštic resonance imaging (MRI) data [1] enables 3D models to be reconstructed and embedded in Portable Document Format (PDF) files [2, 3]. We wish to bring readers' attention to a free resource for 3D MRI images that might be useful for interactive demonstration of lumbosacral structures, specifically relevant to neuraxial blockade: http://diposit.ub.edu/dspace/handle/2445/44844?locale=en (English translation top right of screen)..
