Linking Evidence with Heritage Visualization Using a Large Scale Collaborative Interface

This paper discusses semantic annotation of digital reconstructions of heritage sites. The process of recreating sites of historical interest using computer modelling is now commonplace within archaeology. These approaches allow researchers to explore sites that have been damaged or destroyed in an immersive manner. This research explores methods of semantically annotating graphical elements within the scene so that researchers can explore, document and analyse digital reconstructions and their evidence. The research builds on a complex 3D digital resource linking the 3D scene of the British Empire Exhibition directly with the evidence on which the model was based and providing a customisable toolkit for the spatialised, collaborative annotation of 3D scenes. The project combined an extensible, interoperable ontology (CIDOC-CRM) and technical innovation in the optimisation of data for real-time use and its transfer from a proprietary, non-realtime format to OpenSceneGraph, as well as in new modes of simultaneous, real-time user engagement and interaction via tablet computers within a large-scale 3D environment. The research was funded as an AHRC follow-up scheme to maximise impact and engagement with data. Researchers and members of the public are able to view and interact with the model, either in true, full-scale 3D at the DDS visualisation laboratory in Glasgow, or through a free downloadable application. It is a subject of considerable public interest and showcased DDS visualization facilities to researchers and members of the public.

Paul Chapman was a joint author on this paper that came out of a collaborative research project. Chapman directed the research and provided the 3D visualisation context and guidance for the graphics research and programming elements.
