This week Nick presented at Digital Past 2017 in Newport, Wales. The paper focussed on the digital surveying and subsequent analysis of the fourteenth century medieval vaults in the chancel and north transept of Nantwich St Mary’s Church, Cheshire. This produced two distinct discussions; the first investigating the chancel, which offered an opportunity to hypothesise the medieval design process of the in-situ vaults using reverse engineering. The second, the north transept, contains an incomplete (or possibly destroyed) vault and therefore a series of simulations were developed to postulate the design process, and how the vaults may have looked if completed. 3D digital models of the postulated designs for the north transept can be found on the Nantwich vaults page.
The conference presented numerous exciting and innovative digital heritage projects in Wales and beyond, such as Nick Hannon’s investigations into the Antonine Wall, as well as the Welsh Chapels project which is using games engines as a way of educating the public about heritage.
On the vaults page we have started a map which locates significant Medieval vaults in the British Isles. So far we have included sites already visited and scanned as well as sites we intend to visit. We have also located some initial vaults of interest which may be documented as the project progresses. Please contact us with suggestions of sites to add!
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.
