Abstract
Abstract. The current 3D hype creates a lot of interest in 3D. People go to 3D movies, but are we ready to use 3D in our homes, in our offices, in our communication? Are we ready to deliver real 3D to a general public and use interactive 3D in a meaningful way to enjoy, learn, communicate? The CARARE project is realising this for the moment in the domain of monuments and archaeology, so that real 3D of archaeological sites and European monuments will be available to the general public by 2012. There are several aspects to this endeavour. First of all is the technical aspect of flawlessly delivering 3D content over all platforms and operating systems, without installing software. We have currently a working solution in PDF, but HTML5 will probably be the future. Secondly, there is still little knowledge on how to create 3D learning objects, 3D tourist information or 3D scholarly communication. We are still in a prototype phase when it comes to integrate 3D objects in physical or virtual museums. Nevertheless, Europeana has a tremendous potential as a multi-facetted virtual museum. Finally, 3D has a large potential to act as a hub of information, linking to related 2D imagery, texts, video, sound. We describe how to create such rich, explorable 3D objects that can be used intuitively by the generic Europeana user and what metadata is needed to support the semantic linking.
Highlights
Europeana is the European Digital Library for Culture
By using a metadata standard (EDM) for all European organisations that contribute to Europeana, this portal allows to search for cultural resources over all collections in Europe
PRC can be used as internal format as PRC compression does not harm the vertex colours. Another important technical aspect is the resolution of the ‘professional 3D file’, which can be too high for use by the general public, as it exceeds their requirements and the capabilities of their computers and becomes too large to be transferred over internet
Summary
Europeana is the European Digital Library for Culture. It is structured as a portal with the content itself residing on national servers. For meeting the goals of CARARE and Europeana, we are convinced that the focus of 3D should be on resource exploration, just like with the other formats (text, images, video and sound) that are currently available This means that we consider the linking of information to the 3D model as most. We are convinced that the possibilities of the approach, as we outline here in this text, are far richer and potent than will be used in the CARARE project itself They will be taken into account for inclusion in workflow descriptions to allow deploying this extra functionality in the near future by any cultural heritage organisation that wants to publish 3D resources in Europeana. This means that we need to come up with a solution that is to a certain extent standardised and uniform on all national resource servers, so that the user does not get confused or bored
