Ruthwell Cross 2D/3D scan (April 2012)

The original plan
in the beginning, we envisioned an edition of the two standing crosses and of The Dream of the Rood
separate editions with links between 3D objects and poetic texts
navigation within a single web site, different UI for different objects
this plan proved inadequate, both because new objects were added, and above all for methodological reasons
specific technical problems also related with multidisciplinary issues

1. Heterogeneous material
an edition of Anglo-Saxon texts together with the manuscript scans is not a particular problem (http://vbd.humnet.unipi.it/beta/)in the case of the Visionary Cross project, though, we have to deal with very different objects:
standing crosses → 3D modelsBrussels Cross → photos, 3D modelVercelli Book → manuscript scansrunic inscriptions → 3D, but also text (TEI XML)poetic texts → TEI XML
needed: a flexible environment to integrate the separate components and expose all the connections
critical feature: navigation, inter-object linking

2. A single version for the edition?
a problem faced as soon as we had a working prototype
crucial question: who are our users? what are they going to do with the edition?
two extremes:
a simple 3D viewer based on the SpiderGL library (http://spidergl.org/)
Meshlab (http://meshlab.sourceforge.net/)
User Interface and navigation problems
different features available for different types of users? Is a unified UI going to work?

Roadmap to the edition(s)
first step: “teaching edition” of RC
to be followed by a “research edition”, richer in functionality and with an adjusted UI → same code base, different widget offer/layout
a virtual environment on three levels:
outside church (Google Earth)
inside church (UDK)
single object (3D Viewer)
user testing: currently finishing a first trial, feedback is very important to us

full 2D/3D integration, flexible UI
an open edition:
expansible framework
unnegotiated access to our data
a social edition:
local community
extended community
a distributed edition:
framework on different servers
MESA network (http://mesa-medieval.org/)

Conclusion
our roadmap may look … tentative
in our experience, though, it’s the only suitable path allowing us to build both the technical and methodological tools to deploy the edition
we will need quite a lot of experimenting and of user testing to refine the UI
all the more so when we will start to combine the different editions together (→ Bewcastle Cross scan)
