Last week, the BBC highlighted a 3D fly-through of the Mackintosh Building laser scan data that will be used to help with the building’s restoration and renovation. You can also catch a quick glimpse of the Visualisation lab at the DDS.
The Accord crew were on the road again this week and travelled back to Castlemilk where we met with Kenny Hunter, who is the artist responsible for ‘King of the Castle, and – we can proudly boast- a GSA alumni! Since it was erected in 1999, the artwork has enjoyed a rich and varied life – sometimes a proud Rangers supporter and other days a committed Celtic fan!! This rascal is much loved by the local community, and was chosen by the local ‘How Old Are Yew’ history group to be modelled in 3D. You can find a work-in-progress PDF of our 3D model in the attachment.
Jean Devlin, a member of the ‘How Old Are Yew’ group did a wee bit of extra research and wrote on the Castlemilk History facebook page:
The King of the Castle has had a wee restoration done on him just recently …
After further research by the Castlemilk History Group today, we found out that this was the caption which was on the original coating at the foot of “The King of The Castle”… “Somewhere in the distance is my Future”… It was written by a member of the Castlemilk writer’s group at the time, of which Des Dillon was the writer in residence …
CyArk is an international non-profit organization which is aiming to create a free, 3D online library of the world’s cultural heritage sites before they are lost to natural disasters, destroyed by human aggression or ravaged by the passage of time.
The DDS, along with Historic Scotland through the CDDV partnership has been contributing to CyArk through The Scottish Ten project – digitising heritage sites here in Scotland and internationally.
This week, with help from Microsoft, CyArk relaunched their website with fantastic interactive views of many of the world heritage sites already digitised. The new site looks fantastic, and being able to browse many of the heritage sites in 3D right in the web-browser is a very nice touch. Also fantastic that all three projects featured on the home page are from The Scottish Ten – Mount Rushmore, Rani Ki Vav and the Sydney Opera House.
Browsing the projects, you’ll also find other Scottish Ten sites – Scottish sites including Stirling Castle, St. Kilda, neolithic Orkney. and a further international site – The Eastern Qing tombs in China.
The ACCORD project is working with communities all across Scotland to co-produce 3D models of their heritage using digital technologies. We also have our own blog, here!
ACCORD makes its debut at the V&A!
We were thrilled to have our prints featured at the Digital Design Weekend at the Victoria and Albert Museum, in London from 20-21 September (an event organized as part of the London Design Festival). We are very proud of the work our community groups have achieved and delighted that their heritage has been brought to the world stage through participation in the Victoria and Albert museum’s fantastic weekend of digital culture celebrating co-design!
Natural beauty in breathtaking Camas nan Geall
This is the stunning stretch of coastline where we had the privilege to spend a beautiful August weekend working with the dedicated members of the Ardnamurchan Community Archaeology Group. For a closer look at this pristine slice of Scottish coast, take a virtual peek at Kilchoan Village http://kilchoan.blogspot.co.uk
We explored an 18th century burial aisle in the heart of Camas nan Geall. Check out the wonders of RTI (or Reflectance Transformation Imaging in full) and see how an eroded skull and cross bones on a headstone, supposedly belonging to a Campbell, takes shape, made together with the Ardnamurchan Community Archaeology Group.
The Scientific explanation/RTI for rocket scientists… RTI is a computational photographic method that captures a subject’s surface shape and colour and enables the interactive re-lighting of the subject from any direction. RTI also permits the mathematical enhancement of the subject’s surface shape and colour attributes….
The no-nonsense explanation/RTI for humans… basically, get a £4 shiny black snooker ball, a tripod, and a light… using the movement of the light across the surface of the object the light bounces off the ball and the clever software combines the images to produce these amazing illuminated results – Eureka!
The Rhynie Woman group bring the Pictish Craw Stane to digital life!

The Grimsay Wheelhouse, North Uist
In August 2014, ACCORD sallied forth to the Uists in the Outer Hebrides in order to immortalize in 3D this spectacular example of an Iron Age Wheelhouse dwelling. Together with the Access Archaeology community group, we first recorded the site with photos from the ground and the air using photogrammetry and then with a little help from Agisoft software we produced this awe-inspiring visualization!
And we didn’t just stop there … our next step was to bring the Grimsay Wheelhouse to life in the form of a 3D print – an exact 3D photogrammetric model of the Grimsay Wheelhouse replica to have and to hold!
Working with Hidden Heritage and local community volunteers, Clara was interested in particular in methods accessible at low cost to local community groups that would be strong enough to support the digitization of gravestone and yet be powerful and accurate enough to help uncover hidden detail and support long term archive and conservation projects.
Her results were little short of breath-taking – for example, some of the stones are very badly weathered leaving almost none of the original inscriptions visible to the eye. This can be a significant challenge for heritage groups trying to identify the individuals buried below. Stone 28 at BallyHennan is one of the more badly weathered stones:
Using a method known as RTI (one of two methods Clara used in her project), using around 100 photos and a few hours of additional computer processing significant parts of the inscription suddenly appear:
Last term, students on the DDS’ MSc International Heritage Visualisation course worked as a team to scan the Blacader Aisle at Glasgow Cathedral (access arranged with thanks to Historic Scotland) and the surrounding area. 3D laser scanning (using a Leica C10) was performed over a few days, along with a lot of photography to try to obtain some high quality images for use for texture in the final visualisation.
Students then worked in smaller groups to produce visualisations – this video highlights part of one interactive visualisation running in Unity3D. As well as being able to view the Aisle from different viewpoints, users can also interact with the visualisation to learn more about the windows and the carvings above them.
The aisle (and cathedral) building is incredibly irregular. For example, each window is unique – while all have a similar shape, no two have the same dimensions. The skirt of the aisle likewise has many complex forms. By building this visualisation from data acquired with a 3D laser scanner, we are able to verify the detail to high degree of accuracy – which then has potential to allow models like this to find additional uses in conservation and preservation.
