Cultural Heritage 3D modeling view in Real time: the Forum of Nerva in Rome in the time of Imperial Rome and Medieval Ages

One of the Cultural Heritage application is the possibility to reconstruct past places and environments that appears today as archaeological sites. 3D modeling and the possibility of navigation/view reconstrucions in "real time", allows both scholars and to those who do not have an in-depth scientific knowledge, to be able to understand what was the real shape of an archaeological site in the past. The opportunity is offered by the use of software designed for other areas of interest, such as video games, using tools developed specifically for the video game industry. Procedures coming from the world of video games are transposed in the field of historical reconstruction and 3D modeling. In order to ensure a smooth navigation is necessary to realize 3D models where is good the balance between solid modeling and surfaces modeling with the use of specific texture of historical reconstruction. It is also important to be able to use appropriate algorithms, which allow the simplification o

It is also important to be able to use appropriate algorithms, which allow the simplification of the calculation of the shadows. As a case study is proposed the reconstruction and 3D visualization in "real time" of the Forum of Nerva (in the imperial archaeological center of Rome), so far subject of little interest and study from this point of view, obtained by the game engine of an application open source like Blender. Thanks to the assistance of archaeologists and historians from the point of view of content, and the ability to govern the modeling tools in 3D, by the representative, it is for the first time assumed a reconstruction and exploration of the Forum of Nerva in Imperial Rome and Medieval periods. The most interesting and innovative goal is the ability to switch from the reconstruction of the period of Imperial Rome to the Medieval age, through the use of the "space bar" on the computer keyboard, allowing the "navigator" to make a time leap into the past with a "subjective" view. The displacements in the 3D model can be carried out both with the mode that uses the four letters "W - A - S - D" on the keyboard of the computer, respectively, to go forward, left, back and right, both with the use of a joypad or a pad bluetooth. The application is complete and running .exe file for both Windows and iOS devices, that does not require a previous installation of Blender.
