What is 3D accident simulation? How is it different from animation?
3D simulation offers you the most accurate way to know what really happened before, during, and after an accident. It may be the only way to sort out the often confusing evidence and conflicting witness statements.
Traditionally, reconstruction analysis has been performed manually with relatively little sophistication. Rather than a few pages of simple calculations, simulations perform thousands of calculations and account for phenomenon that can not be studied any other way. We can say the results show what happened based on the law of physics. Animations display anything the animator has in mind. Even though it may look realistic it may be physically impossible.
Because the analysis is three-dimensional, the results an be viewed from any angle or perspective as a real time movie. The inherent complexities of a reconstruction suddenly become easy for the jury to see and understand.
