“…Se trata de las mallas 3D asociadas a los edificios escaneados de la ciudad medieval de Pietrabuona, en Italia. Estas mallas 3D han sido proporcionadas por el Dipartamento di Architettura de la Università degli Studi di Firenze a partir de un estudio de levantamiento completo realizado por profesores y doctorandos (Troiano et al, 2014).…”

“…El procedimiento desarrollado pretende ser un complemento directo para una la aplicación de ayuda en el proceso de anotación semántica en el levantamiento arquitectónico (Troiano et al, 2014). La técnica descrita, no obstante, también podría complementar sistemas BIM (Eastman, Teicholz, Sacks, & Liston, 2008), aplicados en el área del patrimonio cultural, donde se demuestra su eficacia sobre un caso real (Nieto & Moyano, 2014) o con el uso combinado de herramientas de código abierto (Logothetis & Stylianidis, 2016).…”

Lo más destacado:• Se propone un método de segmentación de mallas 3D enfocado a la representación de edificios históricos.• Se utiliza la teoría de grafos para modelar las características de las fachadas y poder encontrarlas automáticamente.• La metodología implementada es adecuada y puede utilizarse en técnicas de levantamiento arquitectónico 3D. Abstract:Advances in three-dimensional (3D) acquisition systems have introduced this technology to more fields of study, such as archaeology or architecture. In the architectural field, scanning a building is one of the first possible steps from which a 3D model can be obtained and can be later used for visualisation and/or feature analysis, thanks to computer-based pattern recognition tools. The automation of these tools allows for temporal savings and has become a strong aid for professionals, so that more and more methods are developed with this objective. In this article, a method for 3D mesh segmentation focused on the representation of historic buildings is proposed. This type of buildings is characterised by having singularities and features in façades, such as doors or windows. The main objective is to recognise these features, understanding them as those parts of the model that differ from the main structure of the building. The idea is to use a recognition algorithm for planar faces that allows users to create a graph showing the connectivity between them, therefore allowing the reflection of the shape of the 3D model. At a later step, this graph is matched against some pre-defined graphs that represent the patterns to look for. Each coincidence between both graphs indicate the position of one of the characteristics sought. The developed method has proved to be effective for feature detection and suitable for inclusion in architectural surveying applications.Keywords: segmentation; 3D meshes; graphs; pattern recognition; features Resumen:Los avances en los sistemas de adquisición tridimensionales (3D) han provocado que este tipo de tecnología se introduzca en cada vez más campos de estudio, como son la arqueología o la arquitectura. En el campo arquitectónico el escaneado de edificios constituye el primer paso con el que se obtienen modelos 3D que más tarde, pueden ser utilizados para la visualización y/o análisis de las características de los mismos edificios, gracias a herramientas informáticas de reconocimiento de patrones. La automatización de estas herramientas permite un ahorro temporal y supone una ayuda a los profesionales, por lo que cada vez más métodos se desarrollan con este objetivo. En este artículo se propone un método de segmentación de mallas 3D enfocado a la representación de edificios históricos. Este tipo de edificios se caracterizan por tener singularidades y elementos característicos en las fachadas, tales como puertas o ventanas. El objetivo principal consiste en reconocer estas características en los edificios, entendiéndose como tales aquellas partes del modelo que difieren de la estructura principal del mismo. La idea es utilizar un ...

“…In other words, "Knowledge of the city, the territory and the environment in the ICT era is a field in which major changes have been taking place for several years now. The digital world of communication is favouring the development of a new cognitive approach based on the realisation of digital models whose content, increasingly dense and articulated, derives from the integration of consolidated knowledge with information acquired with sensing technologies" [26][27][28].…”

The documentation of urban morphology is linked to the complex operation of representing the city, which over the centuries has been undertaken using different methodologies, instruments, and purposes. The “IT revolution” has expanded the possibility of overlapping and relating multiple pieces of information in connection to the urban organism on the same support and, on the other hand, has opened up new scenarios linked to the use of urban digital twins to support the analysis and urban planning. The 21st century has marked a momentous turning point compared to the recent past: the advent of artificial intelligence has in fact allowed the introduction, alongside Urban Information Systems, of ‘Predictive’ Systems, capable of formulating new scenarios on the basis of the elements available and pictured on 3D models. At the same time, the technical and technological acquisitions of the last century have contributed to evident experimentation on the metaverse, which, although it still exists in a de-emphasised form, is currently a whole universe under construction and expansion. Its rules are written with every passing day, in which the individual can recreate a reality similar to, or absolutely antithetical to, the one they experience on a daily basis, populating virtual cities that elude the established urban dynamics of physical structures.

In the field of Cultural Heritage there are many Serious Games applications. 3D models of cultural heritage objects created with 3D modelling methods preserving realism and detail can be a very useful tool for Serious Games if exploited correctly and suitably. In this paper a composite SG application is developed and presented using such realistic 3D models produced by Geomatics techniques. The construction of these 3D models is presented along with the application, which consists of three different options for the user: A virtual navigation to the site with some questions, a visit to the museum of a monument and an educational quiz game concerning the architectural reconstruction of this monument.
