This video presents a walkthrough of a 3D reconstruction of Pompeii's House of the Faun, a structure which dates in its final architectural form to the first quarter of the first century B.C. The walkthrough follows the path from the fauces, across the atrium into the first peristyle, and finally, around the peristyle to the exedra which contained the famous mosaic depicting the Battle of Issus, where Alexander the Great defeated Darius. The sunlight is set to 12:30 PM, December 21, 85 B.C. and proceeds in a timelapse until sunset. The 3D model was created in Autodesk Maya 2008 and rendered with mentalray.
