Diseworth Parish Church Point-Cloud Animation

We have been looking carefully at the laser scan data from one of the surveys we did for our Community Heritage partners the Diseworth Heritage Trust to see the degree to which we can visualize the structural distortion in some of the walls of their parish church, St Michael and All Angels Parish Church in Diseworth, West Leicestershire. This is a very old building – some parts of which are possibly pre-Norman ( before 1066 AD) and our investigation is part of our recent Arts & Humanities Research Council (AHRC) funded Connected Communities initiative in conjunction with the Trust’s Heritage Lottery Fund “All Our Stories” project called “A Thousand Years of History – Diseworth Parish Church from Mercia to Modern Times.” We’ve blogged about it before some time ago here but we thought we’d better show some more up-to-date development images. Animating the point cloud data and exploring it interactively can form a useful way of gaining an overview not only of the building’s external context but also it’s internal arrangement by using a digital “clipping box” to slice the point cloud data of the building up, to  look inside and create sections which gives a real insight into what is going on with the structure of the building. The ability to record internal arrangements of furniture and fittings as well as the fabric of the building means that if the data set is properly curated a very accurate digital record of the 3D form and the visual appearance (in colour) of the building can be maintained. This can be invaluable when Restoration, for whatever reason is required. To demonstrate these two techniques we’ve uploaded a colour video fly-through of the point cloud data from the laser scan of  St Michael and All Angels in Diseworth (see above) which shows the roof removed to we can look inside and we’ve also uploaded some low resolution “clipped” sections and plans (see below) which in the last section clearly shows the displacement of the wall heads outwards caused by the downward and outward thrust of roof trusses. The ability to measure these distortions very accurately (to about a millimeter in this instance) means that small movements in the wall, if any, can be detected in subsequent surveys and appropriate measures can be taken if necessary. However our main purpose in carrying out laser scanning on this building was to get accurate plans and sections in order to create a series of simplified but accurate series of 3D digital models showing the developmental sequence of the church through a number of phases during the last 1000 years. These will be used by the Trust to help to tell the story of the church as it is understood now.
