Artificial Intelligence Alternatives for the Digitisation of Cultural Heritage, 3D Rendering Processes of the Sala Basile in Villa Igiea

The technology integrated with Artificial Intelligence functionality allows the acquisition of real spaces in an increasingly expeditious manner, giving the possibility of digitally configuring complex environments and experimenting with new digital surveying methodologies that differ from the established image/range-based techniques. In recent years, substantial advancements in the fields of computer graphics and computer vision have led to the emergence of innovative approaches, such as Gaussian Splatting, which have revolutionized 3D scene reconstruction and rendering processes. These methods offer remarkable improvements in both realism and computational efficiency. Moreover, in the digital age, the demand for accessible and user-friendly applications is constantly growing, and research is increasingly focused on solutions that offer essential functionality at cost-effective prices. These objectives are mainly pursued by exploiting open-source frameworks, cloud services, and simple methodologies to keep development costs low. The paper aims to validate the results of two Gaussian Splatting processes generated by accessible and user-friendly applications, as well as using simple data as a starting point, such as videos recorded with 360-degree cameras. In this way, the work seeks to evaluate the effectiveness of these innovative techniques in producing high-quality 3D reconstructions, considering the simplicity of the process for users and the associated costs.
