There seems to be many preconceived notions about forensic animations and their overall use in litigation. Many times, lawyers or accident reconstructionists will say that "An animation can show whatever the animator wants" or "Animations are difficult to admit in a court of law". However, to a forensic animator, this is also like saying, that your accountant can "fix your books". In reality, it is far from the truth.

Perhaps it is the fact that so much of what we see on television and in films is altered with lifelike special effects that we tend to associate anything with 3D visualization with more than a hint of skepticism. Ironically, much of the same software used to animate films such as "Spiderman" or "Lord of the rings" is also less known to be used in scientific visualization, research and forensic animations. People may associate the fact that an experienced special effects animator is capable of creating surreal, yet realistic looking effects. Therefore, it must not be accurate.

The greatest difference between a forensic animation and just any other type of animation is the "forensic" part. This implies that there is a large effort in understanding the details of what is being animated and that there is a large emphasis ensuring a high level of accuracy. An animator can spend more than 70% of his time on activities related to the verification of data and ensuring accuracy in the animation.

An experienced and qualified forensic animator would tell you that a large effort goes into building and checking each step of the animation process to the correct and accurate dimensions. In fact, very little is left to the imagination since most recreations are based on accurate data typically provided by the expert witness. A simple example is the terrain data of a particular scene. This can be obtained by means of a total station along with the positions of important features such as signs, traffic lights, debris or tire marks on the roadway.

Even the animation and motion of objects in a 3D recreation is typically based on information or data provided by the expert witness. This data is often obtained through careful calculations or through the use of simulation software. In the case of simulation software, the data can be directly converted or imported directly into the 3D animation software, leaving little room for error.

There may be cases where the forensic animator is provided with less than ideal information, however, even in these rare instances, an experienced forensic animator will have enough knowledge to ensure that the basic rules of geometry and physics (i.e. motion) are applied and adhered to.
