L’espressività del rilievo digitale: possibilità di rappresentazione grafica

Modern technologies used for architectural survey base their operation on the massive acquisition of measurements that are transmitted as point clouds; the development of the instruments allows to obtain a great density of information, such as to provide a realistic visualization of the architectures through the acquired database. The ability to navigate the survey in real time and capture it with images or video reproductions allows you to tell the objects of the measurements with tools similar to those used for the representation of the projects. Analyzing the expressive capacities of the different acquisition systems is more important if we mention the development of technologies in which different data, photographic and laser, are combined into a single database. Within the disciplines of design, the development of digital surveys has offered new possibilities of expression; the research addressed in the paper aims to analyze the evolution of the expressiveness of point clouds, paying particular attention to rapid development of photography.
