Experimentation of a Web Database for Augmented Reality Apps. The case study of ruled geometries

The growing field of Augmented Reality Apps is an indication of greater interest, by private markets and public institutions, towards immersive visualization and those tools that can enhance cultural content through user involvement. An often underrated feature of this digitalization lies in the smart language with which the notions are shown, in quick synthesis based on schemes, slides, lists, images, and comparisons. But the continuous input of data in an app can cause various problems, both on the hardware and software front: from the obvious weight gain, not negligible for pocket devices, to the continuous updating of scientific knowledge, that risks leaving behind all those theoretical contents that are not controlled or renewed. To this is added the problem of the constant maintenance of mobile devices for what concerns software, operating systems, security protocols, and systems for decoding existing data, especially for AR Apps that use audio and video devices. With this in mind, and in order to optimize the performance of mobile tools, a digital archive in the form of an open-source site is useful, providing centralized and pre-cataloged data specifically for use in the AR App. In this way, qualified users can contribute to the knowledge presented through a client-server upload system on the site, properly filtered by semi-automatic security checks. The experimentation of the contribution investigates the advantages and possibilities of such a structured system, setting the case study on the theory of ruled geometries, and the architectures corresponding to them

Il Motel Agip di Mario Ridolfi. Dall’analisi grafica alla rappresentazione parametrica e immersiva

The research aims to describe the process of generation and growth of the architectural form of an unrealized project by Mario Ridolfi, the Agip Motel in Settebagni, through the aid of graphic analysis, geometric and parametric modeling and virtual reality . Versatile architect, with a vast production, well documented by the sources, of completed and unrealized projects, the latter little studied, especially from the point of view of geometry. The abundant presence of design documentation has made it possible to identify and reconstruct the geometric layout on which the motel tower is based: a decagonal matrix plan with star-shaped vertices, in a progression of floors defined by a cylindrical helix. This polycentric trend of the elevation is manifested in a torsion of the building, and in a continuous irregularity of the internal plans, which therefore requires the project a considerable commitment to adapt. Starting from the graphic reconstruction, a 3D model of the plan and a parametric script of the envelope were created, which controls the various functions of the torsion and the different perimeters. Finally, at the end of the restitution, it was decided to reproduce the discrete parametric model in an augmented reality system, with an interactive mechanism for scrolling through the planes of the model and effectively visualizing the evolution of the heights

Chapter Digi Skills Bsc – Revising Graphic Literacy in Bsc Architectural Design Education through a Software-Based Pedagogic Approach. A Shared Pilot Experience at the Politecnico di Milano

The 43rd UID conference, held in Genova, takes up the theme of ‘Dialogues’ as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with ‘others’, which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, “dialogue” as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title ‘translated’ into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences
