Modelado 3D de precisión en procesos de digitalización de escultura construida

Abstract

In contemporary sculpture there are many works that are difficult to digitize in three dimensions using both active and passive procedures. These procedures pose difficulties when applied to constructed sculpture, made from fragments, with thin sheet materials or objects with many cavities and overlaps. Given the impossibility of obtaining optimal results with this type of work, it is necessary to use new strategies that allow obtaining a digital model. For this, it is proposed, exemplified in an object of study, the implementation of precision 3D modeling techniques. Based on the point cloud obtained through active or passive 3D digitization systems, a virtual model is generated using modeling techniques with nurbs surfaces. The result is a 3D model useful for digital processes of cutting, reconstruction, as well as for cataloging or disseminating the work. Opening the possibility of virtual analysis in conservation and restoration processes.
