[00:00.43] The Titanic lies nearly 4,000 metres down in the Atlantic, but she's so huge that in the gloom, cameras can only show tantalising snapshots of the decaying ship – never the whole thing.

[00:11.95] This new full-sized scan reveals the wreck in its entirety.

[00:16.48] Using submersibles, the deep-sea mapping company Magellan, and the documentary makers Atlantic Productions, have created an unprecedented 3D view of the Titanic, enabling the liner to be seen as if the water had been drained away.

[00:40.26] Minute details can be seen, including individual rivets and the serial number on a propeller.

[00:45.86] The team hopes the scan will reveal more about the Titanic and how she sank.
