Gravitate overview

  1. 1. Discovering relationships between artefacts using 3D and semantic data June 2015 – May 2018

  3. 3. © Copyright University of Southampton IT Innovation Centre and other GRAVITATE partners, 2015-2016 We can all do this jigsaw
  4. 4. © Copyright University of Southampton IT Innovation Centre and other GRAVITATE partners, 2015-2016 What if lots of pieces were missing?
  5. 5. © Copyright University of Southampton IT Innovation Centre and other GRAVITATE partners, 2015-2016 What if it was in 3D?
  6. 6. Front Back Faded Cracked Eroded © Copyright University of Southampton IT Innovation Centre and other GRAVITATE partners, 2015-2016 What if the pieces were 2500 years old, were all faded, cracked and with the edges worn away so that they didn’t actually fit together any more?
  7. 7. British Museum Cyprus Museum Ashmolean Museum Fitzwilliam Museum © Copyright University of Southampton IT Innovation Centre and other GRAVITATE partners, 2015-2016 What if the pieces were in 4 different museums?
  8. 8. Jigsaws in 3D most pieces missing all the edges worn off many puzzles jumbled together pieces spread across many countries © Copyright University of Southampton IT Innovation Centre and other GRAVITATE partners, 2015-2016

  10. 10. Re-Assembly You have some (eroded) pieces. The computer fits them together. This is hard in 2 dimensions, never mind in 3D!
