Abstract

Historical architecture often features very detailed elements that are frequently characterized by complex ornamentation, such as capitals, vaulted arches, portals, mouldings etc. Modelling such highly detailed surfaces with traditional software packages can be a very difficult and time-consuming task. This poster discusses the combined use of two software applications to integrate traditional three-dimensional reconstructions of historical architecture and 3D models generated by semi-automatic photo-modelling. Two famous churches in Ravenna were used for the case studies: San Giovanni Evangelista and Spirito Santo. These churches are two outstanding examples of early Christian architecture in Ravenna; built between the 5th and the 6th centuries, they feature excellent examples of the key elements of religious architecture of late antiquity and the medieval period. The aim of the study was to document the modifications made to these churches through the centuries by means of a three-dimensional reconstruction that was chiefly created with the combined use of two open-source software programs: Blender was used to recreate the main structures such as walls, apses, roofs and windows, and Autodesk 123D Catch® was chosen to generate 3D textured models of the most detailed parts: capitals, portals, decorated columns and the ambo of Spirito Santo. The success of this technique demonstrates that the use of a hybrid workflow can simplify the generation of complex shapes, increase the level of detail, and speed up the whole modelling process.
