Editor's Notes

  1. Record material used to guide and evaluate the reconstruction process
  2. Cross sections calculated so as to form a basis for the sculptor to work on. The data was scaled by 1:5 and a plaster model was created for the sculptor to complete.
  3. The completed plaster model was scanned with a resolution of ~1mm. The acquired data of both heads were registered, scaled and integrated with the original surfaces.
  4. After the registration process, the results were analyzed so as to evaluate the alignment and most of the new data were found to be within 1cm of the original surface (green area) In yellow the deviations are up to 2cm and in the red areas the deviations are more than 2cm
  5. the final result was produced by rewrapping the areas of the new data. View of the final completed surface model.
