The scanning process and following reconstruction of the scan data produces a 3-d dataset. Essentially, for every point in space in the object we scan, we get a number that can represent a colour. Using some excellent free software called Drishti – we can turn this data into an explorable computer model. This lets us do fun things like fly though a scroll.
Aside from being a fun video, it is a great way to present the possibilities of our work to archivists, conservators and the general public. You can’t read the ink that is between layers in the video, but you can see hints of its existence and this may provide enough clues to identify the item, or to determine how to further process or conserve the object.
