The HMS Royal Oak was a Revenge-class battleship of the British Royal Navy, the first battleship sunk in the Second World War whilst she was anchored in the Scapa Flow, off the coast of Orkney, Scotland. She was torpedoed by a German U-47 submarine on October 14, 1939, and lost 833 of her crew. In 2006, the Salvage & Marine Operations unit of the UK Ministry of Defence commissioned Archaeological Diving Unit Surveys (ADUS), a collaboration between St Andrews University and Dundee University, to provide sonar images of the Royal Oak. ADUS contacted Holoxica to see if it was possible to put the sonar scan into a 3D hologram. Holoxica took the 1.1M point cloud dataset and managed to convert it into a horizontal format hologram which can be laid flat and it's possible to walk 360 degrees around it, or view it from all sides by mounting it on a turntable.
