    Insourcing, Outsourcing and Crowdsourcing 3D Collection Formation: Perspectives for Cultural Heritage Sites
    (The Eurographics Association, 2012) Kaminski, Jaime; Echavarria, Karina Rodriguez; Arnold, David; Palma, Gianpaolo; Scopigno, Roberto; Proesmans, Marc; Stevenson, James; David Arnold and Jaime Kaminski and Franco Niccolucci and Andre Stork
    This paper presents three different propositions for cultural heritage organisations on how to digitise objects in 3D. It is based on the practical evaluation of three different deployment experiments that use different methods and business models for mass 3D-acquisition. These models are: developing the skills of in-house staff within an organisation, the use of external professionals and using crowdsourcing as a mechanism for developing the 3D collection. Furthermore, the paper provides an analysis of these models, lessons learned and practical recommendations for cultural heritage organisations. The analysis includes considerations of issues such as strategy, size of the organisation, skills, equipment, object accessibility and complexity as well as the cost, time and quality of the 3D technology. The paper concludes that most organisations are able to develop 3D collections but variations in the result will be reflected by the strategic approach they place on innovative 3D technologies.

    Parametric 3D-fitted Frames for Packaging Heritage Artefacts
    (The Eurographics Association, 2012) Sá, Asla M.; Echavarria, Karina Rodriguez; Griffin, Martin; Covill, Derek; Kaminski, Jaime; Arnold, David; David Arnold and Jaime Kaminski and Franco Niccolucci and Andre Stork
    Packing fragile heritage artefacts is a challenge almost all heritage organisations have to deal with when faced with the task of transporting or storing the artefacts. The packaging solution requires fitting the artefact correctly in order to ensure the protection and safety of the item; but also to be easy and cost effective to produce. Different techniques have been traditionally used, such as double boxing, padding negative spaces and cushioning braces. However, the introduction of 3D technologies for documenting these artefacts enables innovative uses of this data for packaging purposes. Hence, this paper proposes the use of the generative modelling language in order to produce unique 3D-fitted containers for packaging heritage artefacts which fit tightly the artefact, and can be made to be reusable and more durable than traditional packaging solutions. We propose to adopt an octet lattice as a low density internal structure to the proposed container. By combining the parametric package design, 3D meshes acquisition and 3D printing techniques, we present a technology based solution to the traditional problem of protecting these valuable artefacts for transportation and/or storing purposes.

    Semantically Rich 3D Documentation for the Preservation of Tangible Heritage
    (The Eurographics Association, 2012) Echavarria, Karina Rodriguez; Theodoridou, Maria; Georgis, Christos; Arnold, David; Doerr, Martin; Stork, Andre; Serna, Sebastian Peña; David Arnold and Jaime Kaminski and Franco Niccolucci and Andre Stork
    Traditionally, 3D acquisition technologies have been used to record heritage artefacts and to support specific tasks such as conservation or provenance verification. These exercises are usually a one-off as the technology and resources required are cost intensive. However, there is a recent impetus on the creation of 3D collections to document heritage artefacts which are semantically enriched by using annotations. A requirement of these solutions is the ability to support several representations of a heritage artefact recorded through time. This paper will propose an infrastructure to systematically enrich 3D shapes in a collection by using propagated annotations. In addition, it will describe the mechanisms for annotating, propagating and structuring the annotations using the CIDOC-CRM ontology. The results of this research have the potential to support heritage organisations in making their semantically rich 3D content available to a wider audience of professionals.
