How Trojan Horses Work

One of the most enduring stories of the Trojan War, the most important conflict in Greek mythology, is the tale of the Trojan horse. Trying to find a way into the city of Troy, the great warrior Odysseus ordered his men to build a massive wooden horse, one big enough for several Greek soldiers to fit in. Once the structure was finished, he and several other warriors climbed inside, while the rest of the Greeks sailed away from Troy. One man named Sinon, however, stayed behind in order to deceive the Trojans, convincing them that his fellow Greeks had betrayed him and fled from the city. The wooden horse, he told the Trojans, was safe and would bring them luck.

After some discussion over the matter, the Trojans agreed to wheel the horse through their gates, unknowingly giving the Greek enemy access to the city. After proclaiming victory and partying all night, the citizens of Troy went to sleep -- it was then that Odysseus and his men crept out of the Trojan horse and wreaked havoc on the city.

­Although you've probably heard of the Trojan horse from Greek mythology, chances are you've also heard of Trojan horses in reference to computers. Trojan horses are common but dangerous programs that hide within other seemingly harmless programs. They work the same way the ancient Trojan horse did: Once they're installed, the program will infect other files throughout your system and potentially wreak havoc on your computer. They can even send important information from your computer over the Internet to the developer of the virus. The developer can then essentially control your computer, slowing your system's activity or causing your machine to crash.

­Though they're not actually viruses, they're referred to as "Trojan horse viruses," "Trojan viruses," "Trojan horses" or just plain "Trojans." Regardless of what people call them, they all mean same thing. But what happened? How did you let this Trojan horse into your computer in the first place? And what can you do stop one from getting in?

Amazing New Motion Capture Tech Makes Games Look Like Films


Check out this amazing new video on YouTube.  It's a short clip on the making of the upcoming video game, L.A. Noire.  Specifically, it focuses on a new motion capture technology called MotionScan, which creates the most lifelike scenes yet.



Brendan McNamara, lead developer  for L A Noire, has said that “We’re definitely blurring the lines now. I want this game to be the flashpoint where people start to think of games and film as being on the same level, because I’m confident they already are.”  It's hard to argue after seeing the footage.  The company behind MotionScan is depth Analysis, based in Sydney, Australia. Depth Analysis announced the innovation earlier this year, and gave a few hints about how it works.

"MotionScan uses 32 High Definition cameras to capture true-to-life three-dimensional performances at up to 30 frames per second," the company revealed. "Capable of capturing up to 50 minutes of final footage and processing up to 20 minutes of facial animation automatically per day, the technology revolutionizes traditional motion-capture and post-production animation. MotionScan records every emotional detail, mannerism, and facial nuance accurately frame by frame as 3D models.  No markers or phosphorescent paint needs to be applied to the actors at the time of recording, and no manpower is required to clean up data and animate the finer details by hand after the shoot. For directors and cinematographers, an additional advantage of MotionScan is the ability to view an actor’s performance from any angle and re-light in any way from one take without the need for multiple camera and lighting setups that quickly drain production time and budgets."

This comes at a momentous time for motion-capture innovation.  Microsoft, of course, recently rolled out the Kinect motion-sensing camera for the Xbox 360.  The Kinect is sort of the DIY version of MotionScan, letting gamers transport themselves into the action.  It'll be interesting to see how this increased realism impacts game development in the coming year.  Perhaps most significantly, it may lead more A-List Hollywood actors into games.   After all, as one can see by the LA Noire footage (which features an actor from the hit show Mad Men) there's more "acting" that can actually come through now given the mocap precision.

LA Noire, which is made by Rockstar Games, will likely be a breakthrough title, ushering in a new era of cinematic game play.  With so much attention focused now on smaller, social games like Farmville, cinematic epics are primed for reinvention.   I have no doubt that while gamers may be spending more time on iPhones, there's always an appetite for big brash immersive epics like LA Noire.
