La rappresentazione basata sulla visualizzazio-ne della realtà acquisita mediante sensori attivi e passivi ha permesso di ripensare il tradiziona-le iter conoscitivo e comunicativo. L’approccio di vitruviana memoria è stato sostituito dalla vi-sualizzazione discreta di grandi quantità di punti-immagine. Le coordinate image-/ range-based permettono di superare i limiti del disegno o dell’immagine fotografica, configurando un mo-dello 3D esplorabile in ogni direzione e dettaglio anche da remoto. Procedure automatiche e semi-automatiche gestiscono le informazioni per pas-sare al controllo numerico dei modelli. Innumerevoli articoli scientifici trattano dell’at-tendibilità certificata dei dati o dell’ottimizzazio-ne dei modelli. Diversi sono i saggi che discutono dell’avanzamento delle istruzioni programmate per automatizzare il riconoscimento “intelligen-te” delle componenti nei flussi di lavoro Building Information Modeling (BIM) e Heritage Building Information Modelling (H-BIM). Invece, sono an- cora poche le trattazioni sul valore euristico in-dotto dall’impiego dei percorsi speditivi. Le fasi di acquisizione, elaborazione, sintesi critica e comu-nicazione delle elaborazioni sono oggi comprese in un’unica filiera che vede al centro l’uso delle Information and Communication Technologies (ICT) per rilevare e trasferire il palinsesto d’infor-mazioni da archiviare. Questo processo di fusione è ricaduto sulle modalità della ricerca e della di-dattica, ma anche inerenti al modo di divulgare e coinvolgere i cittadini per attrarre consensi e con essi le risorse necessarie alla gestione politica dei beni ereditati. Da queste considerazioni ci è sembrato opportu-no ricontestualizzare un processo che non si limiti alla valorizzazione di operazioni rapide e semplifi-cate, in alternativa a calcoli congruenti con le fina-lità del progetto o del rilievo. Con la “chiamata” a questo numero, si è infatti voluto proporre e solle-citare una più ampia riflessione sulle tendenze di ricerca in atto, favorendo la discussione sui limiti e sulle potenzialità dei processi di automazione avanzata in relazione al confronto fra prassi con-solidate e innovative. La consapevolezza maturata con il linguaggio di-gitale mostra il diffuso recupero della logica geo-metrica. Una realtà evidente nei testi che trattano della rappresentazione digitale dei sistemi voltati complessi o delle soluzioni progettuali basate sul-la rivisitazione del concetto vitruviano di sceno-grafia. Meno evidenti, ma non per questo meno di-rimenti, sono le argomentazioni geometriche che sostengono soluzioni quad-dominant remeshing o di retopology secondo il lessico della computer graphics. Anche nei procedimenti di reverse modelling si riscontrano raffinate soluzioni geometriche per migliorare l’analisi e i dettagli applicabili a “copie fedeli” del prodotto ricostruito virtualmente per controllare il cambiamento del duale stato fisico. Parallelamente, l’evoluzione del linguaggio digi-tale con i servizi offerti dalla rete, valorizzano l’e- ISSN 1828-5961 Modelli Digitali 3D / Accessibilità e Fruizione Inclusiva sperienza fisica, ibridandola con l’ausilio di conte-nuti virtuali per orientare esperienze significative. In questa duplice prospettiva il titolo del volume allude al percorso, ciclico e interattivo, che uni-sce senza confondere, la costruzione di modelli image- e range-based per mediare al loro interno spazi di collaborazione adatti alla divulgazione at-tiva delle conoscenze.

Abstract
Representation based on the visualization of real-ity, acquired through active and passive sensors, has allowed a rethinking of the traditional cog-nitive and communicative process. The Vitruvian approach has been replaced by the discrete visu-alization of large number of point-images. Image-or range-based coordinates allow to overcome the limitations of the drawing or photographic image, configuring a 3D model that can be ex-plored in any direction and detail, even remote-ly. Automatic and semi-automatic procedures manage the information to be conveyed to the numerical control of the models. Many scientific papers deal with the certified reliability of the data or the optimization of the models; several papers discuss the development of programmed instructions to automate the “in-telligent” recognition of components in Building Information Modeling (BIM) and Heritage Build-ing Information Modeling (H-BIM) workflows. However, few discussions focus on the heuristic value of using time-saving procedures. The phas-es of acquisition, processing, critical synthesis, and communication of results are now included in a single workflow centered on the use of Infor-mation and Communication Technologies (ICT) to capture and transfer the archived information framework. This unified process has affected re-search and teaching methods, as well as the way in which information is disseminated and citizens are involved, in order to obtain the approval and thus the resources needed for the political man-agement of heritage. Starting from these considerations, it seemed ap-propriate to recontextualize a process that is not limited to the improvement of fast and simplified operations, as an alternative to calculations con-gruent with the purpose of the project or survey. Indeed, the call for this issue was intended to propose and encourage a broader reflection of current research trends and to stimulate discus-sion on the limits and potentials of advanced au-tomation processes in relation to the comparison of established and innovative practices. The awareness gained from digital language shows the widespread reconsideration of ge-ometric logic. A trend that can be clearly seen in the papers dealing with the digital representation of complex vaulted systems or design solutions based on the reinterpretation of the Vitruvian concept of scenography.
