Stereoscopic 3D imaging was first developed in 1838 to demonstrate how the human brain processes the images received from the eyes. Each eye takes an individual snapshot from their respective viewpoints and the brain stitches this information together into a single image. The final image that we see contains information about perspective, object occlusion, color and size, allowing us to place individual objects in the context of its environment. Stereoscopic 3d imaging is merely an enhancement of the illusion of depth that we perceive when we look at everyday things. Describing stereoscopy as a "trick" is technically inaccurate, since the final image our brain sees is a processed composite from our binocular vision, whether the source is a regular 2D photograph or a stereoscopic image.
Although the idea behind 3D sounds quite simple, implementing an effective stereoscopic 3D video gaming solution is another matter entirely. It requires sufficiently mature advancement in display technologies and an equally robust video driver that is updated frequently. Thankfully, after several years, LCD technology has caught up with the 60Hz-per-eye requirement of shutter-glass stereo optics that Nvidia has been pioneering for home use. With a dedicated, in-house 3D driver team, Nvidia is able to provide constant updates to over 400 3D Vision compatible game titles, including the newest and most popular games, like Call of Duty and StarCraft II.
Official 3D Vision support for StarCraft II came with the 1.1.0 patch. This update includes numerous bug fixes to the 3D Vision game play, as well as a stereoscopic 3D panel in the StarCraft II options menu (F10). Even before the official patch went live (and even when StarCraft II was still in the beta testing stages), stereoscopic 3D support using Nvidia 3D Vision was already surprisingly functional, despite the absence of any 3D Vision profiles. With the 1.1.0 patch, the 3D Vision rating is upgraded from “unrated” to “good,” improving 3D game play elements, like 3D rendered cursors and health bars, and fixed 3D portraits.
