The video is used to demonstrate how far from the intersection the vehicles were as they approached impact. Example animationĪn expert produces a video showing two vehicles approaching an intersection. As such, it may require some investigation to determine if a video comes from a computer simulation or just an animation. A computer simulation may also produce a video with the results of the simulation. In contrast, a computer simulation involves calculations that ultimately form part of the basis for the expert’s opinion. Therefore, an animation is just a demonstrative exhibit. An animation is usually a video demonstrating an expert’s opinion or a witness’s description of an incident. But this distinction is important for how the court will evaluate its acceptability. Animation or Computer Simulation?ĭetermining whether the opposing expert has created an animation or a computer simulation may not be initially obvious. If an opposing expert relies on a simulation, how do you know if it’s reliable? Here, I’m discussing how you can parse valid, scientific techniques in computer simulations from junk science that should be excluded before trial. But computer simulations can also be full of unrealistic assumptions and invalid techniques. This includes accident reconstruction and biomechanics to fire investigation and product design. Computer simulation can be a very powerful tool in a variety of fields.
