To move the light position in the interactive RTI, make sure the lightbulb icon in the bottom right corner is highlighted rather than dark then click and drag across the viewer.
To pan around the image, turn the lightbulb icon off, and click and drag across the viewer.
Use the layers icon to enable enhanced views of the RTI, including diffuse and specular (mathematical enhancements that remove colour and increase contrast), and normals (a false-coloured static view of the surface profile).
Having a better view of the many complex textures of this densely decorated pot reveal numerous insights into its construction, such as the incised decoration and the horizontal striations that suggest it was thrown on a wheel. Being able to view the texture without the colour using the specular, diffuse and normals layers also makes it easier to distinguish colour patterns from textures, which can be difficult to interpret using conventional photographs.
This is part of a teaching collection used by the University Department of Archaeology and History. The RTI was created as part of a joint project between the Department and the Digital Humanities Lab to digitise artefacts from these collections to enable students to study them more easily.
