Computational tools for modelling masonry domes

As part of a funded research project on Neapolitan domes, we developed MaDoMa (Masonry Domes Maker), a parametric model for generating different types of domes. The aim was to test MaDoMa in various contexts, making it accessible also to non-expert users through a userfriendly interface. From a methodological point of view, the research was based on the semantic decomposition of the dome macro-element and the mapping of Neapolitan domes. From a methodological point of view, the research was based on the semantic decomposition of the dome macro-element and the mapping of Neapolitan domes. Thus, the reference parameters and geometric rules were defined to build an adaptive algorithmic model in VPL (Visual Programming Language). Testing the algorithm on several real cases allows the tool to be refined, improving its adaptability. The tool makes it possible to generate approximate models of existing domes according to the shape grammar principle, with user-customisable levels of detail. In the research, the integration of the VPL model into BIM systems will be experimented with, comparing the level of detail and modification of the domes produced with those obtainable through object-oriented parametric tools typical of BIM software. At the same time, intuitive interfaces will be developed to facilitate use by non-expert users. MaDoMa allows rapid and customisable generation of 3D models adaptable to different architectural configurations. The expected results aim to demonstrate the effectiveness of the parametric model in ensuring speed and accuracy for expeditious surveys and the creation of communicative artefacts for the enhancement of cultural heritage.
