Outils numériques pour le relevé architectural et la restitution archéologique

Abstract : This thesis studies the process that leads from digital 3D acquisition to the creation of virtual models intended for architecture and archaeology. It begins with the study of 3D acquisition techniques used, the lasergrammetry and architectural photogrammetry, and follows with a detailed comparative analysis of these devices, based on multiple experiments carried out during collaborations between the MAP-CRAI and the MAP-PAGE . Then, a study on architectural morphology is approached around its typological and architectonic alternatives, followed by the theoretical questions raised by 3D modeling and more specifically architectural modeling. Various experiments are then presented, which form the basis for a study of the development of digital tools intended to facilitate architectural geometrical modeling. The principal contribution of this thesis is the association of this empirical study with an analytical approach based on our theoretical knowledge in architecture, which leads to the identification of constrained geometrical primitives, mouldings. The digital tools developed this way in a CAD software define these adjustable geometrical primitives of which the initial field of application, specific to the classical architecture, will be extended to Khmer architecture. Finally, a more advanced proposal corresponding to the teleology of this thesis to obtain in an effective way a result complying with the requirements of architectural and archaeological modeling , is integrated in a CG program.
