The process is a beautiful fusion of mathematics, photography, and computer graphics. Photogrammetry is the process of shooting and analyzing hundreds of photographs of a given subject and processing/calculating the images into an extremely accurate, textured, 3D digital model. By offering a virtual reality through the synthesizing of digital imaging, cultural heritage sites continue to support research and become place-based learning environments.Īrc/k actively promotes, teaches and shares photogrammetry to empower citizen scientists, volunteers, cultural heritage organizations and indigenous communities to document and archive their own cultural heritage in new and powerful ways, while adhering to ethical practices. With photogrammetry, Arc/k is able to make hyper-accurate 3D digital archives, creating an authentic snapshot in time as well as a baseline for future renovation, repair, and preservation. While Arc/k remains open to any type of technology that can be used to digitally archive culture, we do believe that photogrammetry is a particularly unique fusion of mathematics, photography and computer graphics which lends itself well to the citizen scientist model that Arc/k has been promulgating. 3D digital archives can be used in both virtual and augmented reality for a variety of uses in educational, academic, and general settings. Arc/k aims to move the field forward with approaches to using technology which facilitate access, expand resources, and/or increase archiving productivity. The technique won't get a wide range of use when there are only so many ancient scrolls to go around, but it hints that even the most fragile pieces of written history are no longer off-limits.The Arc/k Project is an early-adopter and innovator in technology to digitally preserve cultural heritage in 3D and Virtual Reality. However, the results were worth it in this case: the researchers discovered that this is the earliest known copy of a Pentateuchal book from the Bible (Leviticus) to be found in a Holy Ark, dating back "at least" 1,500 years. The process is slow, as you have to piece together segments and reconstruct lines of text that have been lost to the ages. The team used a high-resolution volumetric scan to create a 3D model of the scroll, looked for bright pixels in the model (a sign of where the ink would be) and virtually flattened the scroll to make text segments readable. Researchers in Israel and the US have conducted the first "virtual unwrapping" of a heavily damaged scroll, the En-Gedi scroll, to read its contents without destroying what's left. The scientific world is developing a knack for reading texts without opening them.
