  • 摘要:The problem of the quality of architectural representation, in a dynamic use finalized in web or database publication, represents the main theme of the current debate regarding the ways in which to share knowledge between different disciplinary fields. Starting with the surveying operations with the laser scanner technology, it is possible to obtain complex three-dimensional models that, through the three-dimensional photogrammetry and UV mapping systems, are integrated in a useful model for various studies. The numeric models, however, that are characterized by a high level of detail cannot be used in web navigation; the restitution of formal, dimensional and chromatic data explain a communication problem linked by the expansion of it's users and the quality of the information transmitted. Therefore, the construction of a web site that organizes the acquired and elaborated materials require two different categories of models: one linked by immediate web navigation and one in high detail that is capable of accurately describing the studied object. In such a system, the three-dimensional models become instruments of immediate visual communication, providing many links for in-depth examination. The diminishing of geometric information is substituted with maps that represent detailed and embossed maps. The normal-map are capable of increasing the perceptive quality of the low-poly models because it can substitute the normals of the model with the one obtained by RGB bitmaps that associate the components of the normal vector to the faces of the detailed numeric model with these three canals. The synergy use of the PHP language, database MySQL and VRML allows for the creation of a web site that gives the user the opportunity to study the object differently, visualizing the outcomes in real time
