Death-crash case sets a legal precedent.
A jury reached a unanimous verdict of not guilty on Mr Shaun Ore, aged 33, of Allerton Lane, Hateley Heath, West Bromwich, who had denied causing the death of Mr Kenneth Stevens by dangerous driving.
Computer animation was used for the first time in a court in the UK to show a reconstruction of the fatal road accident in Portland Road, Edgbaston, on August 31 last year.
But the jury rejected the prosecution's version of the accident shown in the two-minute colour video.
Mr Ore, who was on mobile patrol for security firm Elite, based in Acocks Green, claimed he approached the junction with Gillott Road at 40mph.
He said he did not see Mr Stevens in a Triumph Herald car and when he hit it he put on the brakes.
The prosecution claimed Mr Ore, who was driving a Land Rover Defender, was driving too fast at more than 57mph in a 30mph limit in wet conditions.
But Mr Robert Juckes, prosecuting, accepted Mr Stevens had been drinking and had been at fault over the accident by pulling out in front of Mr Ore.
The events leading up to the accident were recreated using new computer software, called Autodesk 3D Studio Max.
The two-minute sequence, developed by traffic officers in West Midlands Police, was designed to bring to life detailed drawings and crash scene photographs.
The officer who has spent six years developing the computer software and produced the video said he was not disappointed by the jury's decision.
Pc Mike Doyle said after the verdict: "The jury has come to a result and we respect that decision. We put evidence forward. Whether it is accepted or not is a matter for the jury.
"The 3D animation was accurate in as much as the information put into it was correct. The mathematics were spot on."
