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.
