In my opinion, one of the most important aspects of creating three dimensional models and animations for the legal industry is that the more accurate the visuals are the more effective the presentation is. Creating a fair and accurate presentation is the only way to enable the visuals to be admissible into evidence for a trial. There is no room for error, unlike a mediation where visual aids are more persuasive and not bound by legal rules. If the presentation is not fair and accurate during a trial when the animator has to testify on the stand, they will be torn apart by the opposing side of the case. This could cause a completely different outcome resulting in a benefit to them instead of your side.
The first stage in the accuracy process is to collect all the photographs and as much data and measurements as possible. Even if this requires going back to the scene of where the incident took place after the majority of the data has been collected from the clients and experts. The more measurements the better, and all of the additional details help.
If all this is done in the very beginning, not only does it help ensure that everything in the digital world matches up with the real world, but it also makes things easier in the building process. Having all this vital information speeds up the production time astronomically because of not having to go back and find bits and pieces of missing data. For instance if you only have the height and depth of an object but not the width, it causes you to not only risk admissibility but also makes the production time much longer than necessary.
When the virtual world is being presented in a trial, and is fair and accurate, it can be extremely helpful to the side it's being used for. The jury can now see multiple angles of an incident they would never have been able to see before with the use of 3D animation. New levels of detail can be noticed in close up camera shots and a better understanding of the incident as a whole can now be perceived.
