How are Forensic Computer Animations Created?

Animations are created with a scientific accuracy based on compiling a lot of data, and physical evidence.

We are relying on evidence like tire marks, debris, scratch patterns, vehicle damage in cases of motor vehicle accidents.  We take all the engineering evidence and use that evidence to provide a foundation for the animation.  This foundation and the scientific method used is one of the fundamental criteria’s used by a judge to decide whether or not that animation is accepted by the courts.  It’s not just somebody else’s vision of the accident.  It is this scientific reliable data which is the foundation and base for the animation.  We use sophisticated, validated engineering programs such as PC Crash that will find the motion of the vehicles before the accident, during the accident, and after the accident.  There is a lot of science that goes into that.
