Speaking of archaeological VR, the London Charter is worth consideration. Its objectives are below (I think the last one on the list is especially important), but there’s a lot of material to mull over…
The London Charter seeks to establish principles for the use of 3d visualisation methods and outcomes in the research and communication of cultural heritage in order to:
Provide a benchmark having widespread recognition among stakeholders.
Promote intellectual and technical rigour in such uses.
Enable appropriate evaluative criteria and methods to be determined and applied.
Stimulate debate on methodological issues.
Offer a robust foundation upon which specialist subject communities can build detailed standards and guides.
Ensure appropriate access and sustainability strategies to be determined and applied.
Enable 3d visualisation authoritatively to contribute to the study, interpretation and management of cultural heritage assets.
