January 12, 2009 Today's 3D games are already programmed to take depth of field into account as part of their game world graphics rendering. Your graphics card already knows exactly how far away the objects it's crunching are. So it's really only display and driver restraints that have prevented us from seeing our existing 3D games in a truly immersive stereoscopic 3D format. Vegas CES 2009 has shown us some extremely promising, and already affordable, stereoscopic 3D display technologies that work with the majority of recent release 3D games and take a big step forward towards the ultimate goal of virtual reality home gaming. We'll take a look at NVIDIA's 3D Vision system and iZ3D's stereoscopic monitors, which approach the task from different angles and give us a glimpse of what we can expect when 3D technologies flood the mainstream in years to come.
