Javols Anderitum VR application

Here is a project created in collaboration with IGO ordered by a client.
The goal was to create a virtual city for in-game VR display. I didn't start from scratch because the ancient Roman city of Javols already had a 3D model and some illustrations as references to start. So to begin with, it was necessary to respect the rules of the client and of the scientific council in terms of historical coherence, the placement of the city, its buildings and of course the technical constraints linked to a city on a VR support. First, I isolated each unique building (forum, amphitheater, temple, ...) then I identified a number of house patterns to reproduce the city districts without too much repetition between the different houses. Once all these buildings were modeled and textured (modular system for houses, roofs, shutters / doors), I created their LODs, their MIP Maps for optimization and everything integrated into Unity. Then we had to place all the buildings to form the city in the 3D software, keeping the coordinates of each to use a script that creates a position map. This map generates the city of Javols in Unity from the city of the 3D software, in fact it places all the integrated buildings (containing their LODs, their shaders, etc.) previously in Unity, which allows you to have a less heavy and complete scene.
