Modelling Medieval Vaults – Call for Papers

Modelling Medieval Vaults symposium at the University of Liverpool in London, 14 July 2016.

Through the University of Liverpool’s Interdisciplinary Network Fund we are organising a symposium primarily exploring the use of digital techniques to analyse medieval vaults. The synopsis can be found below and on our events page.

The use of digital surveying and analysis techniques, such as laser scanning, photogrammetry, 3D reconstructions or reverse engineering offers the opportunity to re-examine historic works of architecture. In the context of medieval vaults, this has enabled new research into three-dimensional design processes, construction methods, structural engineering, building archaeology and relationships between buildings.

Recent research on Continental European and Central American vaults has established the significance of these techniques, however, as yet there has been little exploitation of digital technologies in the context of medieval vaults in the British Isles. This is despite international recognition of the importance of thirteenth and fourteenth-century English vault design to the history of Gothic architecture in an international context.

The aims of the present symposium are to present new research in this emerging field in order to establish appropriate methodologies using digital tools and identify significant questions for future research in the area.

Abstracts (500 words maximum) are invited for 20 minute papers on the following subjects:

  • Representation and analysis of medieval vaults using digital technologies.
  • Investigations of British tierceron, lierne or fan vaults.
  • Digital techniques used for the analysis of historic works of architecture applicable to gothic vaulted buildings.

Our intention is that proceedings will be published in a suitable journal.

Deadline for abstracts: Friday 13th May 2016

Enquiries and abstracts to be addressed to Nick Webb email.

Symposium date: Thursday 14th July 2016

Location: The University of Liverpool in London, Finsbury Square.

 

Digital Past 2016

On 10th and 11th February 2016 Nick attended Digital Past 2016, an annual conference organised by the Royal Commission on the Ancient Monuments of Wales focussing on the use of digital tools and techniques in the context of heritage assets.

Projects linked closely to the vaults research were particularly informative, for example Dr Maurice Murphy’s use of laser scan data in conjunction with Historic Building Information Modelling (HBIM) to serve as conservation and analysis documents. In the context of the vaults project, we are keen to investigate the use of HBIM to assist in our continuing analysis of the geometry of medieval vaults, which is very complex in terms of the amount of geometric data gathered. An Irish government funded project 3D-Icons was very revealing in terms of the processes required to create accessible digital models of significant monuments and buildings. For example, converting laser scan data to mesh models with rendered textures, and finally making these easily viewable to the public.

The conference presented a number of other intriguing projects, for example Professor Bob Stone’s use of drones and immersive virtual reality to inspire communities to engage with local histories, as well as the use of Gigapixel photography to document Welsh chapels and make available the interactive views online. The Cynefin project to digitise Tithe maps showed how Gigapixel photography can be used to copy large and delicate maps without damaging the original, and their consequent overlay with modern digital maps to provide a free resource for the public and researchers to use.

The conference was a great success and we look forward to returning next year, where we hope to present an update of the vaults project.

Scanning at Nantwich St Mary’s Church

On Friday 13th November 2015 we visited Nantwich St Mary’s to scan the medieval vaults in the choir, as well as the intriguing reconstructed vaults in the crossing by George Gilbert Scott. Below is a timelapse video showing the laser scanner in action in the choir operated by Nick, whilst J.R. records the vaults for photogrammetry purposes, and Alex provides a short guided tour of the sculpture on the misericords in the medieval choir stalls.

Even with the timelapse speed, the rotation of the scanner seems slow. The individual scan provides a point cloud model of the architecture immediately around it, which when combined with other scans, gives a highly detailed and accurate point cloud of the entire vaults in the choir. The next stage of the process will be to interpret the data using a number of digital modelling techniques in order to provide a better understanding of the underlying vault geometry.
