Integrating wooden altarpieces into H-BIM: Geometric profiling, complex artworks, and digital heritage mapping

In the study and conservation of Cultural Heritage, various disciplines contribute to the research aimed at extracting information from both historical objects and heritage buildings. The contribution of this work is part of an interdisciplinary process to model, register, and evaluate complex models of knowledge. Evaluate a complex model, where there are works of art made of wood, painting, and sculpture. The results demonstrate a process of analysis and geometric characterisation of the shapes, in which most of the profiles are worked with a new methodology of the Best Fit Model (BFMP), and in which its analysis represents a deviation between a range of 7 and 9 mm. The development of low-relief models is based on the Poisson reconstruction equation, applied through a variable workflow using multiple software tools. Furthermore, an Entity Information Matrix (EIM) is introduced, enhancing the exchange and classification of architectural data. This study supports the integration of real-world 3D scans into BIM environments, providing a replicable model particularly suited for the digitization of altarpieces and façades. • The challenge of bringing altarpiece into BIM lies in structuring the work on geometry modelling and data acquisition techniques, and training operators to work BIM platforms. • The modelling and exporting of artworks as meshes into BIM is a complex challenge, requiring precision to ensure that these elements integrate properly with BIM software. • The Entity Information Matrix is a pioneering tool that classifies architectural structures for easier identification in BIM environments. • HBIM project models an altarpiece by Juan Martínez Montañés, incorporating geometric characterisation of the profile units woodwork, painting, and sculpture, to create new identities and spaces for future research.
