3D Roof Scan
We are delighted to share with you an example model of St Alfege Church roof void with the chamber above the chancel and the organ loft. These scans were conducted by Simon Withers, who teaches architecture at the University of Greenwich and is leading on a 3D scanning project which forms part of the Heart of Greenwich project (supported by the National Lottery Heritage Fund). Talking about how the 3D scanning works, Withers explains: "It's a laser that spins horizontally and vertically, operating in a sphere and collecting data on everything it hits. It collects a million points of data per second and builds an accurate model, meaning that you can display buildings in a way that has never been done before.”
Various different parts of the church both internally and externally have been scanned in detail over a two-year period and turned into 3D models which will be accessible for visitors via a heritage touchscreen installed in the church in 2020.
Operating instructions to help you explore this test model are as outlined below.
