ANALYSE is a program
intended for the creation and analysis of vehicle motion
paths. Its general application lies in the generation of
motion paths for use in 3D computer graphic animation,
and in particular the reconstruction of vehicle
trajectories for forensic studies.

The ANALYSE program defines
a motion path in terms of various types of legs
(acceleration, constant velocity turn,
decelerating turn, etc). It can then process
these legs at a user-defined time increment
(frame rate) to create an overall motion path.
Performance data at each time increment is stored
for further analysis, and the data generated can
also be used to automatically produce a motion
path within a 3D animation program.
The primary aim of the ANALYSE program is to
permit the generation of motion data rapidly and
reliably, and avoid the need for laborous hand
calculations. It also permits the creation of 3D
animated motion paths with a high degree of
control over those motion paths created.
ANALYSE can provide results using both metric and
imperial units, and currently generates animation
data at any user-defined frame rate between 1 and
100 frames per second. Each successive motion leg
uses the end conditions from the previous leg as
the starting condition for that new leg, thereby
guaranteeing a continuous, seamless motion path.
Where a straight path leg follows a curved path
leg, that leg will be at a true tangent to the
last frame position on the curved leg. There can
be an unlimited number of legs defined, with the
ending conditions of one leg (velocity, distance
travelled, time) become the starting conditions
for the next leg.

ANALYSE uses 3DLINX by Global Majic to
implement the real-time motion path replay
functionality contained within the program.
The background to the development of
this program is as follows. We were originally approached
in early 1999 by a Forensic Analysis specialising in car
accident investigation. We were requested to create the
vehicle motion paths for a particular vehicle accident,
for use in a computer-animated recreation of that
The motion path calculations were done manually, which
proved to be a long and tedious operation. After the
motion paths were completed, the legal advisers involved
in this case requested a number of additional paths be
modelled and the existing ones altered, within a very
short time frame. It became clearly apparent that not
only was the manual creation process tedious, but also
time consuming, inflexible and prone to the introduction
of calculation errors.
ANALYSE was originally conceived as a temporary program,
intended to automate some of the more basic and
repetitious calculations involved in determining vehicle
motions. It grew from that point to become a more
complete solution to the definition of vehicle motion
paths for computer animation.
Beyond the requirements of computer animation, the
definition and calculation of motion paths can also yield
useful physical data about the performance of the
vehicles themselves, such as distances, velocities and
accelerations at any point along the specified motion
path. ANALYSE will output time histories of all these
The time savings and control of calculation errors which
can arise during manual determination of vehicle motion
paths should mean ANALYSE would pay for itself, just in
the labour saved, in its first commercial application.
ANALYSE draws on techniques acquired during our several
years of experience working in the field of computer
simulation of military aircraft (fast jet) performance
prediction and flight testing.
