Abstract
Abstract. The 3D reconstruction of cultural heritage artefacts plays a crucial role in documentation, conservation and dissemination. While recent advances in photogrammetry, laser scanning and neural rendering techniques have significantly improved the geometric accuracy and visual realism of digitised assets, the reconstruction of transparent and reflective materials - typical in museal collections - remains a major challenge. Materials such as glass, glazes and varnishes exhibit complex optical behaviours, leading to incomplete or inaccurate 3D models. Recent developments in Gaussian Splatting (GS) offer a potential alternative by enabling efficient, high-fidelity scene representation without explicit surface modelling. However, their application to non-Lambertian and transparent heritage objects remains largely unexplored. This paper presents a study on GS methods for the 3D digitisation of transparent cultural heritage artefacts. Through a series of experimental reconstructions, the work investigates the potential and limitations of GS, highlight the opportunities of hybrid pipelines for addressing long-standing challenges in the digitisation of non-collaborative materials.
A Distortion-Aware Ray Sampling Neural Radiance Field (DARS-NeRF) framework that integrates distortion-aware ray sampling with structure–material–lighting decoupled modeling is proposed, providing an effective paradigm for virtual museums, digital preservation, remote education, and high-fidelity intelligent visual sen...
Cultural heritage documentation increasingly relies on image-based 3D surface reconstruction, with photogrammetry software making such workflows accessible to archaeologists, conservators, and heritage technicians. These tools have been successful for conventional multi-view acquisition, but they do not routinely explo...

Experimental results demonstrate that combining feature enhancement with opacity control improves the visibility of internal depth relationships and point-density variations in complex wooden architecture, thereby supporting structural understanding that is difficult to achieve with conventional rendering.

Physical inspections in various contexts (industrial, operational, medical, etc.) often require surface analysis, but how is it possible to review or improve past inspections retrospectively, even when the object under investigation is no longer available? Classical photogrammetry enables 3D reconstructions but oft...

The 3D geometric documentation of cultural heritage monuments requires spatial datasets that are accurate, complete and suitable for conservation, monitoring, visualization and heritage management. However, complex geometries, occlusions, limited accessibility, vegetation and other field-acquisition constraints often p...
