Visualization of architectural works by photogrammetry: a compromise between measurement and representation

Architectural works are carefully planned before they are erected. They are the result of an elaborated and logical process. The survey of a building is thus a singular problem compared to the contingent constitution of the rural survey. Architectural modeling can therefore be enriched beyond its dimensional knowledge by adding to it the architectural knowledge that permitted its construction. The virtual model of an element of architecture is significant when it becomes displayable. 3D visualization is however a translation of information provided by a model. The result obtained is a communication tool, not a vehicle for knowledge. The data used for its construction is transformed in order to satisfy the illusion. The geometry and textures are adjusted together. The visualization mission of the Promenade du Peyrou is an occasion for us to apply our principles of analysis to the remote acquisition survey.
