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).
This view of a pot sherd was taken using a RTI dome and a basic DSLR camera on a horizontal-arm tripod. The result provides an interactive view of the sherd, allowing better study of its decoration and how the sand, mud and water of the river Thames has altered its surface texture.
