Vehicle Motion Path Creation and Analysis
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.

Simple Input of Motion Path data
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.

3DLINX Web Site

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 accident.

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 parameters.

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.
