    Digital Workflow for Creating 3D Puzzles to Engage Audiences in the Interpretation of Archaeological Artefacts
    (The Eurographics Association, 2018) Echavarria, Karina Rodriguez; Samaroudi, Myrsini; Sablatnig, Robert and Wimmer, Michael
    3D physical puzzles are typically used to engage audiences in the interpretation of archaeological artefacts in a museum exhibition. The reason for this is that a puzzle can be seen as a game but also as a complex activity that archaeologists undertake to re-assemble fragments. The contribution of this paper is a novel digital worfklow for the design and fabrication of 3D heritage puzzles. The input to the workflow is an authentic artefact from a heritage collection, which is then digitised using technologies such as 3D scanning and 3D modelling. Thereafter, a puzzle generator produces the 3D puzzle pieces using a cell fracture algorithm and generates a set of puzzle pieces (female) and a single core piece (male) for fabrication. Finally, the pieces are fabricated using 3D printing technology and post-processed to facilitate the puzzle assembly. To demonstrate the workflow, we deploy the proposed method to create a 3D puzzle of an artefact, the Saltdean urn, for the Archaeological Gallery of the Brighton Museum and Art Gallery. The significance of this research is that it eases the task of creating puzzle-like activities and maintaining them within a busy museum gallery.

    VR-assisted Architectural Design in a Heritage Site: the Sagrada Família Case Study
    (The Eurographics Association, 2018) Andujar, Carlos; Brunet, Pere; Buxareu, Jerónimo; Fons, Joan; Laguarda, Narcís; Pascual, Jordi; Pelechano, Nuria; Sablatnig, Robert and Wimmer, Michael
    Virtual Reality (VR) simulations have long been proposed to allow users to explore both yet-to-built buildings in architectural design, and ancient, remote or disappeared buildings in cultural heritage. In this paper we describe an on-going VR project on an UNESCO World Heritage Site that simultaneously addresses both scenarios: supporting architects in the task of designing the remaining parts of a large unfinished building, and simulating existing parts that define the environment that new designs must conform to. The main challenge for the team of architects is to advance towards the project completion being faithful to the original Gaudí's project, since many plans, drawings and plaster models were lost. We analyze the main requirements for collaborative architectural design in such a unique scenario, describe the main technical challenges, and discuss the lessons learned after one year of use of the system.
