摘要：In the last decade, the new technology of laser scanning has improved the architectural and archaeological survey. This instrument measures millions and millions of points in a short time. But the more interesting and above all more difficult goal is, up till now, the data processing. Using several procedures and testing some softwares it is possible to generate a 3D mesh with different resolution. It is useful when the single parts of the architectonic object present a variety of aspects. The triangles of the mesh can be decimated referring to planar surfaces without many details. On the contrary it will be necessary to refine the parts regarding decorations, bas- reliefs, statues and so on. This kind of procedures generates a 3D mesh easier to manage in the realization of a virtual reality scenario. Furthermore the textures applied at the same resolution too, allow to reconstruct the object faithfully and to explore it on the net on-line. The application regards a recent survey of the fa.ade of the Ancona Dome by Mensi GS100 Laser Scanning
