“…Recently, Kelly & Wonka (2011), introduced a methodology where the concept of a generalized extrusion is applied on a building through a set of profiles. Once the extrusion has been applied, the result is a complete mass model for a new building, which can be enhanced with elements such as windows and doors.…”

Abstract:With the rise of available computing capabilities, structural analysis has recently become a key tool for building assessment usually managed by art historians, curators, and other specialist related to the study and preservation of ancient buildings. On the other hand, the flourishing field of procedural modeling has provided some exciting breakthroughs for the recreation of lost buildings and urban structures. However, there is a surprising lack of literature to enable the production of procedural-based buildings taking into account structural analysis, which has proven to be a crucial element for the recreation of faithful masonry structures. In order to perform an in-depth study of the advances in this type of analysis for cultural heritage buildings, we performed a study focused on procedural modeling that make use of structural analysis methods, especially in its application to historic masonry buildings such as churches and cathedrals. Moreover, with the aim of improving the knowledge about structural analysis of procedurally-recreated historical buildings, we have taken a geometric structure, added a set of procedural walls structured in masonry bricks, and studied its behavior in a generic, freely-available simulation tool, thus showing the feasibility of its analysis with nonspecialized tools. This not only has allowed us to understand and learn how the different parameter values of a masonry structure can affect the results of the simulation, but also has proven that this kind of simulations can be easily integrated in an off-the-shelf procedural modeling tool, enabling this kind of analysis for a wide variety of historical studies, or restoration and preservation actions.Key words: procedural modeling, virtual historical buildings, masonry structures, stable structures Resumen:Con el creciente aumento de las capacidades computacionales, el análisis estructural se ha convertido en una herramienta clave para la evaluación del estudio y conservación de edificios antiguos por parte de los historiadores del arte, curadores y otros especialistas. Por otro lado, el floreciente campo del modelado procedural ha proporcionado avances interesantes para la reconstrucción de edificios y estructuras urbanas no accesibles. Sin embargo, hay una sorprendente falta de métodos que permiten la generación de edificios procedurales, teniendo en cuenta el análisis estructural, los cuales han demostrado ser un elemento crucial para la concepción de estructuras de mampostería. Con el fin de realizar un estudio en profundidad de los avances en este tipo de análisis para edificios del patrimonio cultural, se realizó un estudio centrado en el rol del modelado procedural que realizan métodos de análisis estructural, especialmente en su aplicación a los edificios históricos de albañilería, tales como iglesias y catedrales. Por otra parte, con el objetivo de mejorar el conocimiento sobre el análisis estructural de los edificios históricos concebidos proceduralmente, hemos tomado una estructura geométrica de un atrículo, a...

“…As this information is generally given in an architect paper plan, it will require the production of simple tools in order to ease its capture. Some propositions have been made to generate 3D buildings from footprints with smart extrusions [46], and the surveyor just has to capture the building footprint in the plan and choose the right parameters to produce the roof. In the case where a digital model is attached to the permit request, the model has to be integrated into the dataset.…”

Abstract:The Right to Build is defined by textual elements that determine what an owner can build on a parcel. Such regulations contain elements that can influence the development of territories. Expressed through legal texts, their effects on the territory are difficult to assess because of the documents' complexity and of the diversity of urban configurations. In this paper, we present a generic and extendable model to represent such regulations. This model is based on (1) a representation of geographical concepts (attributes, features and relations) mentioned in regulations and (2) rules formalized with Object Constraints Language (OCL). We also propose an implementation that allows the handling of formalized rules in order to check if a building configuration proposal respects urban regulations. Many applications are possible in order to assist in the conception of such regulations, land acquisition strategy or territorial evolution studies, in this article, we notably describe a future application dedicated to assist building permit surveyors.

“…It is an important topic in computer graphics and GIS, and there have been several initiatives to develop procedural engines for modelling urban features. For instance, buildings (Wonka et al, 2003, Müller et al, 2006, Kelly and Wonka, 2011, Besuievsky and Patow, 2013a, landmarks (Rodrigues et al, 2010), roads (Beneš et al, 2014), plants (Lintermann and Deussen, 1999), monuments (Koehl and Roussel, 2015), and land parcels (Vanegas et al, 2012). For a comprehensive list see the overview in (Smelik et al, 2014).…”

ABSTRACT:The production and dissemination of semantic 3D city models is rapidly increasing benefiting a growing number of use cases. However, their availability in multiple LODs and in the CityGML format is still problematic in practice. This hinders applications and experiments where multi-LOD datasets are required as input, for instance, to determine the performance of different LODs in a spatial analysis. An alternative approach to obtain 3D city models is to generate them with procedural modelling, which is-as we discuss in this paperwell suited as a method to source multi-LOD datasets useful for a number of applications. However, procedural modelling has not yet been employed for this purpose. Therefore, we have developed RANDOM3DCITY, an experimental procedural modelling engine for generating synthetic datasets of buildings and other urban features. The engine is designed to produce models in CityGML and does so in multiple LODs. Besides the generation of multiple geometric LODs, we implement the realisation of multiple levels of spatiosemantic coherence, geometric reference variants, and indoor representations. As a result of their permutations, each building can be generated in 392 different CityGML representations, an unprecedented number of modelling variants of the same feature. The datasets produced by RANDOM3DCITY are suited for several applications, as we show in this paper with documented uses. The developed engine is available under an open-source licence at Github at http://github.com/tudelft3d/Random3Dcity.
