simulators

Moving through real-life battlefields inevitably proves trickier than playing a game of Minesweeper, but Spanish researchers and army officers have converted the video game Panzer General into a simulator that can test troop maneuver algorithms based on ant colony behavior.

First-person-shooter video games have nothing on a new combat simulator by defense giant Raytheon. Fully rigged warfighters can roam freely in the real world and engage unseen virtual enemies through their VR goggles, tossing real flash-bang grenades and even shaking off the muscle-numbing effects of getting shot.

This simulator goes far beyond the olden days of the board game "Operation." Last month, for the first time, neurosurgeons rehearsed on a 3-D model of a patient's brain just hours before removing a brain tumor for real.

When I slipped behind the wheel of the traffic simulator at Israel's Ben Gurion University recently, it was less than two minutes before I was bumping into the virtual cars and swerving around pedestrians. Maneuvering through the tree-lined urban roads projected in dayglo colors on giant screens was tricky--and I wasn't even one of their hard-drinking or toking research subjects.

Passenger-car gasoline in Italy costs the equivalent of around nine bucks a gallon. Formula One racing fuel goes for several euros more. And at a (full-speed) fuel consumption rate of between three and four miles per gallon, Ferrari's F1 cars can burn through heaps of Italian green during track testing. That's one reason the company, along with a few other F1-entrenched firms, are betting on the latest virtualization tech to help shave a few Euros off the high cost of testing.
