Virtual Stonehenge
IDIA Lab has developed a simulation of Stonehenge in Unity 3D which illustrates the various stages of construction and celestial alignments in an interactive virtual simulator. The project incorporates IDIA Lab’s CelestialEngine which uses NASA JPL data to accurately position the sun, moon and visible planets – correcting for changes in time in the Earth’s rotation and other forces – allowing for accurate observations of the night sky as they would have appeared thousands of years ago at Stonehenge.
The History Channel’s television series featured this project on their Universe series. http://www.history.com/shows/the-universe/episodes
