|History||the compilation of different sources of information available (Arenberg map 1609, remarkable reference books, expert consultation, etc.) for a solid interpretation of our model|
|Architecture||the synthesis of knowledge in medieval fortifications and all its elements of passive or active defenses.|
|Archeology||the synthesis with all the adequate precision of the recorded traces of the past.|
|Géography||a first control of the use of satellite images|
|data processing||the use of a range of tools ranging from computer model design to satellite data processing, rendering and animation software, image processing, etc.|
|Mathematics||a good view in space and good notions of descriptive geometry for the re-construction of the model in 3D|
|Arts||a judicious approach creating an atmosphere and not a "dry" computer reconstruction.|
|1. Data acquisition.||
The data will be of different types: archaeological, bibliographic or investigative. Arenberg's map of 1609 with Neufchâteau and its provost is the cornerstone of the exercise. Without this great oil painting the reconstruction of the city would be impossible. A second document from the past is a drawing of Lieutenant Louis de Frahan in 1657 entitled "Castrum Desolationis". These documents will be completed by the magnificent book "Histoire du Pays de Neufchâteau. La ville. La seigneurie. Le Ban de Mellier" de A. Geubel et L. Gourdet, 1956. Some interesting studies of Mr H. Gratia, the book of synthesis of Mr Kellen and the periodic bulletins of the "Terre de Neufchâteau" club are also very useful for the reconstruction. The information will be complemented by the results of excavations as well as reference works on medieval architecture.
|2. 3D geometric construction.||
After data collection follows the implementation. Each piece of data must be transcribed into geometric information in a 3D environment. The configuration of the ground with its mesh will be obtained after satellite image processing available to the general public. The location of the buildings will be inspired by the in-depth analysis of Mr Geubel and Mr Gourdet. This study of 1956 is undeniably robust after the confirmation of excavations almost fifty later! If the plan view suffers little uncertainty after the recent excavations it is quite different from the view in elevation where some university textbooks will prove necessary for the construction of a realistic 3D model.
|3. Definition of materials and textures.||
Little information has come to us to ensure the materials used. The ruins of the castle are today bare stone masonry while the map of Arenberg shows a castle in white. What about habitat? Probably a mix of hard buildings and other more modest mud and thatch houses. Nature was also somewhat different: no big spruce forests, some modest side roads ... There will be many assumptions about this environment.
|4. Static rendering.||
After the implementation of the 3D model and the application of surfaces and textures the photographic part can begin with the static rendering of some particular views to give a general impression of the castle and its village. These views will be used to compare the configuration of the Middle Ages with that of today.
|5. 3D Animation.||
The static view leaves only a very partial impression. The volumes and the relative dispositions of the buildings are badly perceived. A large number of photographs are necessary to have a complete understanding of the environment. This perception in space can very quickly become a difficult task. 3D animation with the help of a moving camera solves this problem. A small video throughout this space reveals the layout of the buildings and the layout of the field in a relaxing and pleasant way. The addition of everyday characters will make this mural more vivid.
|6. Immersion - Virtual Reality.||
Recent technology of the last decade, virtual reality allows immersion in the environment with the help of a helmet designed for this purpose. We are an integral part of the decor. The environment absorbs us entirely. Virtual reality is the ultimate stage of 3D modeling. This will end this project with the ambitious goal of walking the streets of Neufchâteau in the sixteenth century !
