3D Vision (previously GeForce 3D Vision) is a stereoscopic gaming kit from Nvidia which consists of LC shutter glasses and driver software which enables stereoscopic vision for any Direct3D game, with various degrees of compatibility. There have been many examples of shutter glasses over the past decade, but the NVIDIA 3D Vision gaming kit introduced in 2008 made this technology available for mainstream consumers and PC gamers.
The kit is specially designed for 120 Hz LCD monitors but is compatible with CRT monitors (some of which may work at 1024×768×120 Hz and even higher refresh rates), DLP-projectors, and others. It requires a compatible graphics card from Nvidia (GeForce 200 series or later).
The glasses use wireless IR protocol and can be charged from a USB cable, allowing around 60 hours of continuous use.
The wireless emitter connects to the USB port and interfaces with the underlying driver software. It also contains a VESA Stereo port for connecting supported DLP TV sets, although standalone operation without a PC with installed Nvidia 3D Vision driver is not allowed.
NVIDIA includes one pair of shutter glasses in their 3D Vision kit, SKU 942-10701-0003. Each lens operates at 60 Hz, and alternate to create a 120 Hz 3-dimensional experience.
This version of 3D Vision supports select 120 Hz monitors, 720p DLP projectors, and passive-polarized displays from Zalman.
The stereo driver software can perform automatic stereoscopic conversion by using the 3D models submitted by the application and rendering two stereoscopic views instead of the standard mono view. The automatic driver works in two modes: fully "automatic" mode, where 3D Vision driver controls screen depth (convergence) and stereo separation, and "explicit" mode, where control over screen depth, separation, and textures is performed by the game developer with the use of proprietary NVAPI.
