For this next phase of the project, the virtual reconstruction of the eastern side of the Lisbon’s Royal Courtyard (Terreiro do Paço) just before it was destroyed by the 1755 earthquake was updated, as new research corrected the earlier sketches.
The façades of the Opera House were redone, as well as the Palace Gardens. The Clock Tower by Canevari was more accurately modelled. Thanks to a reasonably detailed blueprint for the Patriarchal Church, this whole area was done from scratch, with the western façades inspired by an existing engraving showing one of the remaining buildings. The blueprint also shows a far more precise layout of Capela Street in the decade before the earthquake, which implied a major change of the existing modelled street.
Thanks to a more advanced rendering engine developed by Linden Lab for their Second Life viewer, the new images and the video below are now able to display projected shadows. The underlying server technology was upgraded to OpenSimulator 0.6.6.
Developed for CHAIA (University of Évora) by Beta Technologies, the project was presented at the 15th International Conference on Virtual Systems and Multimedia (VSMM 2009), which took place in Vienna, Austria, 9-12 September, 2009.
