An unprecedented two-year scanning project has produced the first-ever "digital twin" of the Titanic wreckage, offering new insights into the 1912 disaster.

New details about the sinking of the famed ocean liner, RMS Titanic, in 1912 have been revealed by a 3D virtual replica created by British deep-sea mapping company, Magellan Limited. The model features in a newly released National Geographic documentary,

The project, led by National Geographic and Atlantic Productions for a new documentary titled Titanic: The Digital Resurrection, marks the first time the entire wreck has been mapped in such detail

A new documentary explores the tragic final night of the RMS Titanic with the most detailed digital reconstruction of the ship ever created.

The scan provides a new view of a boiler room, confirming eye-witness accounts that engineers worked right to the end to keep the ship's lights on. And a computer simulation also suggests that punctures in the hull the size of A4 pieces of paper led to the ship's demise.

Now our understanding of how the Titanic sank could be transformed thanks to the creation of a digital twin of the wreckage based on 3D scans (see our pick of the best 3D scanners if you want to scan somewhat smaller objects).
