Computer animations are routinely developed in order to communicate complex sequences of events and/or display elements affected by the incident that may be invisible by any other means. 3D models provide a third dimensional view of the scene and allow the scene to be recreated from various viewpoints, including those of eyewitnesses, participants, and also from overhead perspectives. By superimposing computer-generated 3D models into actual photographic scenes, we are able to create animated reconstructions of accidents.
