  49. 49. Stereo
  50. 50. Stereo and timeline The two paralel fields can contain now and then images, and down there can be a timeline (see the next image) The different landmarks of Lisbon (rebuilt or not) can be identified as in the guided tour or in the game designed as seen in the example (own application). The timeline can thus identify the temporal layers (as done also in the Lisbon pre 1755 earthquake project) The map can be the 3D image

  73. 73. Bucharest destructured zone
  74. 74. Conclusions A concept of the development of an application to visualise the impact of the 1755 earthquake on Lisbon has been developed Following existing approaches this can be done in a real time 3D application (modelling of the landmarks) combined with the 3D features of the same application for identifying the various effects on the monuments and the layers in the urban development
  75. 75. Conclusions (continued) The concept can be exported to Bucharest The research can be continued building digital databases on features of the rebuild of Lisbon and their employment given the today's development (green walls) – future collaboration The implementation of the concept in the software is subject of future collaboration as well Comparisons are open from Lisbon to Bucharest and l'Aquila (the later to were subject of the doctorate)
