Abstract

This paper describes the combination of visualization techniques with animation to visualize geometrical and temporal engineering data created as part of a two vehicle accident investigation. The exemplar case discussed involved recreating the collision between an airborne motorcycle having jumped a hill and a three wheeled all terrain vehicle approaching the hill from the side opposite that of the motorcycle. Potential visibility of the all terrain vehicle's safety flag was critical to a litigation. The paper discusses the visualization of the recreated collision as viewed from a number of vantage points, including the motorcycle operator's perspective. Photogrammetry and conventional surveying techniques were employed to generate a three dimensional geometrical computer model of the hill. The hill had been leveled prior to the accident investigation. Matching photographs of the site taken at the time of the accident to images generated by the computer was necessary to validate the computer model. This process is discussed. Motion data for the two vehicles were generated based on eye witness reports and traditional accident investigation techniques. These data were visualized in a computer generated recreation of the accident.
