GRAVITATE A platform for the Re-Unification, Re-Association and Re-Assembly of Cultural Heritage artefacts
The structure of the presentation
• How was the project born and what problems does Gravitate address?
• How does the platform work and what can you do with it?
• 3D data quality - 3D models for advanced computing
Introducing the issues - the case study of Salamis
• Accessibility
• Quantity of data to be studied
• Fragmentation
Re-Unification Re-Association Re-Assembly

Re-Unification - a virtual repository Physically separated objects can be re-unified digitally in a repository comprising semantic AND geometric data
Data enrichment
• Calculation of geometric properties (e.g. facets, average thickness, 2D and 3D patterns, curvature, colour etc.)
• Semantic enrichment through Natural Language Processing (NLP)
Re-Association – search / visualization / analysis
The Web – Client : semantic and geometric search
The Web – Client : semantic and geometric search
Similarity by: • Colour • Curvature • 2D and 3D pattern • Shape • Thickness • Rugosity
The Desktop-Client : Visualization and Comparison of fragments and their properties
Re-Association – search / visualization / analysis
The Desktop-Client : Visualization and Comparison of fragments and their properties -
Curvature, colour distribution, facets,…
Annotations with a fixed vocabulary that feed the metadata
Re-Association – search / visualization / analysis
Re-Assembly – semi automatic reassembly and template
Work projects and documenting the process
3D data quality – 3D models for advanced computing
This looks like a nice model, but…
It has: • 150 Self-Intersections • 2 Non-Manifold Edges • 2 Small Holes • 207 Shells
3D acquisition and post-processing – a GRAVITATE experience
• 3D data capture – scanning versus structure from motion
• Post-processing – MeshLab versus Geomagic Wrap
Thank you for your attention
