Unprecedented 3D Scans Reveal New Insights into Titanic Shipwreck.

Researchers have completed the first full-size digital scan of the Titanic, using two remotely operated submersibles to map the whole shipwreck and the surrounding 3-mile debris field, where personal belongings of the ocean liner's passengers were scattered. The resulting data, including 715,000 images, is 10 times larger than any underwater 3D model ever attempted before. A documentary on the project is expected to come out next year, and the new technology will help researchers work out details of how the Titanic met its fate and allow people to interact with history in a fresh way.
