Vehicle Accidents

Vehicle accidents are dynamic by nature - typically, one or more of the objects of interest were moving at the time of the accident. 3D animation is the ideal tool for analysis and presentation of evidence concerning dynamic events - by definition, animation involves moving objects over time. Using the 3D Working Model, the expert can determine what happened and the results of this analysis can be presented in a clear, compelling format via real-time animation.

Vehicle accident animations are crated in three parts:

1. Creating the scale 3D model of the scene. This can be done using existing plans and survey data or by capturing the information through Laser Scanning Steve Note:Perhaps show a picture of existing plan data and a pic of a Laser Scan...
   
   
2. Creating the scale models of the objects of interest such as passenger vehicles, tractor trailer, heavy equiomet or pedestrian. As in creating the scene, the object models can be based upon existing dimensional data or from laser scan data capture
   
   
3. Once the models are completed and verified for dimensional accuracy, the motion is imparted. Generally, the expert witness provides motion data to the animator, describing the Position (x,y,& z) and Rotation (roll, pitch & yaw) of each object over time. The process of moving the 3D objects in accordance to the expert's analyses is called keyframing. PSI's animations are keyframed at time intervals as fine as 1/4800th of a second, providing the ultimate in engineering fidelity.
