Abstract
Abstract. In recent years, an increase in international investment in hardware and software technology to support programs that adopt algorithms for photomodeling or data management from laser scanners significantly reduced the costs of operations in support of Augmented Reality and Virtual Reality, designed to generate real-time explorable digital environments integrated to virtual stereoscopic headset. The research analyzes transversal methodologies related to the acquisition of these technologies in order to intervene directly on the phenomenon of acquiring the current VR tools within a specific workflow, in light of any issues related to the intensive use of such devices , outlining a quick overview of the possible "virtual migration" phenomenon, assuming a possible integration with the new internet hyper-speed systems, capable of triggering a massive cyberspace colonization process that paradoxically would also affect the everyday life and more in general, on human space perception. The contribution aims at analyzing the application systems used for low cost 3d photogrammetry by means of a precise pipeline, clarifying how a 3d model is generated, automatically retopologized, textured by color painting or photo-cloning techniques, and optimized for parametric insertion on virtual exploration platforms. Workflow analysis will follow some case studies related to photomodeling, digital retopology and "virtual 3d transfer" of some small archaeological artifacts and an architectural compartment corresponding to the pronaus of Aurum, a building designed in the 1940s by Michelucci. All operations will be conducted on cheap or free licensed software that today offer almost the same performance as their paid counterparts, progressively improving in the data processing speed and management.
Highlights
The evolution of the spatial concept in the virtual sense coincides more and more with a substantial transformation of the perception of contemporary spaces, linked to factors specific to Information Technology
We witness a multiplication of more and more user friendly programs that adopting algorithms acts to Photomodelling, or management of data from recovery systems Laser scanner, functional to generate a three-dimensional copy of elements directly cultured from reality and in functional parallel to interactive and virtual design, in order to generate easy real-time explorable digital environments (RTR) on ever widespread virtual platforms such as Unreal engine or Unity, integrated progressively with interactive hardware such as VR Homido V2 or Google Daydream View, optical viewers similar to the famous Oculus Rift, which can accommodate all kinds of iOS and Android smartphones
The reduction of production costs and of the commercial product favored the gradual emergence of new three-dimensional data acquisition criteria and the subsequent transfer to immersive scenario editing platforms by the active use of HMD virtual devices, triggering an technical and instrumental upgrading process of the world of work, and in particular of architectural design, museum teaching, medical field and video gaming entertainment, thanks to the results achieved in a better empathic link between virtual visitor and reconfigured spaces digitally, surpassing in fluidity of execution and ease of use, any other system of interaction with the simulated environments
Summary
The evolution of the spatial concept in the virtual sense coincides more and more with a substantial transformation of the perception of contemporary spaces, linked to factors specific to Information Technology.
