About OpenRTI
OpenRTI is an open-access platform for publishing, examining and citing RTI datasets of cultural heritage objects.
Publications usually reproduce only a few still images chosen by the author; the datasets behind them stay unpublished, so a proposed reading cannot be checked under other lighting. OpenRTI makes these datasets openly accessible for examination, comparison and citation, guided by the FAIR principles (findable, accessible, interoperable, reusable).
About the project →What RTI shows
Beyond a single photograph
Enhancements computed from RTI data make fine detail and overall shape easier to see: some separate relief from colour, others show the estimated orientation of each point on the surface.
