Subjective and objective assessment of 3D textured and non-textured Cultural Heritage Artefacts.

Abstract

—The core mission of museums and cultural institutions is the preservation, study and presentation of cultural heritage content. As public expectation for more open access to information and innovative digital media increases, this is being met in cultural heritage with the creation of 3D digital artefacts using methods such as non-contact laser scanning. However, many issues need to be addressed including how the visual quality of presented dataset to the public affects their perceptual experience with the artefact. The results presented in this paper demonstrate the importance of the relationship between texture and polygonal resolution and how this can affect the perceived visual experience of a visitor. It also finds that there is an acceptable cost to texture and polygonal resolution to offer the best perceptual experience with 3D digital cultural heritage artefacts.
