TECHNIQUES

Step By Step The following list outlines the step by step process we take in developing and producing each computer visualization we create. Based on the needs and complexity of the case, this process can take from two weeks to two months.

  • All available case material is analyzed by each team member on the project.
  • A meeting is held with attorney and/or experts to determine the scope of the simulation - i.e. the number of points of view, the number of scenarios, the number of motion paths, etc.
  • Storyboards of the proposed simulation are developed and created.
  • Foundation material is collected, analyzed, and verified.
  • Scenes and models are built to scale based on the established foundation.
  • Objects are animated according to motion paths provided by counsel's accident reconstructionist.
  • Titles, time lines, distance counters, diagrams, and any other presentation needs are added.
  • The final simulation is recorded to a VHS tape or CD-ROM and delivered to our client.

Foundational Accuracy Visual Forensics maintains rigorous engineering and scientific standards for assessing visual elements, in both the field and in the computer lab, ensuring foundational accuracy for the simulations we produce. Depictions of events are based on data from police investigation reports, professional survey data, high resolution aerial photography, scene photographs and video, reconstructionist measurements and motion path data/analysis, meteorological reports and expert analysis.

At the completion of each project, the Visual Forensics team on the job produces a comprehensive foundational report detailing the source of every critical element of the simulation. In addition to these reports, we use a multitude of techniques in the simulations themselves to show all litigation participants how our accuracy is achieved.

For example, whenever possible we fade from actual pictures of the objects and/or vehicles involved in the incident to the models we build in the simulation to demonstrate strict adherence to the evidence available.

The images above are an example of how we fade from an actual photograph of a train to the computer model created for the simulation. See the Fades section in our online portfolio for more examples of this technique.

If video is available, we can create a split screen with the computer simulation running in unison along side of the video reenactment. This technique is very helpful in demonstrating how the computer simulation adheres to the reality of the factors and/or conditions in the case such as traction and skidding as seen in the example below.

Tools Of The Trade Visual Forensics applies a variety of technical tools and multimedia resources to produce scientifically sound, visually compelling computer simulations. In addition to the case foundation data, our modelers and animators use state of the art computer workstations and graphic programs to build the 3D environments in which the incident is recreated.
