LG Helping YouTube Go 3D
According to PCWorld, "That video can be directly uploaded to YouTube via a dedicated YouTube 3D video application." YouTube, for its part, has actually been playing in the 3D space for some time. Google's video hub began offering a place for 3D video back in July 2009 at the YouTube 3D Gallery, and has sold special 3D glasses ever since.
Per VentureBeat, the glasses-free 3D screen on the Optimus 3D was made with an "applied parallax barrier technology," which puts a series of slits on the front of the LCD screen that block light in a way that ensures a user's left and right eye see different images in order to creating the illusion of depth.
