would issue a sequence of rapidly alternating left–right movement commands to the console, producing a kind of "wiggle stereoscopy" effect additionally aided by the wired LC shutter glasses which worked in sync with these movements. The kit arrived too late in the product cycle of the console when it was effectively replaced by the PlayStation 3, and only a few games were supported, so it was largely ignored by gamers. The USB-based Nvidia 3D Vision kit released in 2008 supports CRT monitors capable of 100, 110, or 120 Hz refresh rates, as well as 120 Hz LCD monitors. Hardware Active shutter 3D system providers There are many sources of low-cost 3D glasses. IO glasses are the most common glasses in this category. XpanD 3D is a manufacturer of shutter glasses, with over 1000 cinemas currently using XpanD glasses. With the release of this technology to the home-viewer market as of 2009, many other manufacturers are now developing their own LC shutter glasses, such as Unipolar International Limited, Accupix Co., Ltd, Panasonic, Samsung, and Sony. The M-3DI Standard, announced by Panasonic Corporation together with XPAND 3D in March 2011, aims to provide industry-wide compatibility and standardization of LC (Active) Shutter Glasses. Samsung has developed active 3D glasses that are and utilize lens and frame technology pioneered by Silhouette, who creates glasses for NASA. Nvidia makes a 3D Vision kit for the PC; it comes with 3D shutter glasses, a transmitter, and special graphics driver software. While regular LCD monitors run at 60 Hz, a 120 Hz monitor is required to use 3D Vision. Other well known providers of active 3D glasses include EStar America and Optoma. Both companies produce 3D Glasses compatible with a variety of technologies, including RF, DLP Link and Bluetooth. DLP 3D In 2007, Texas Instruments introduced stereo 3D capable DLP solutions to its OEMs, Samsung and Mitsubishi then introduced the first 3D ready DLP televisions, and DLP 3D projectors came later. These solutions utilize the inherent speed advantage of the Digital Micro-mirror Device (DMD) to sequentially generate a high refresh rate for the left and right views required for stereoscopic imaging. DLP 3D technology uses the SmoothPicture wobulation algorithm and relies on the properties of modern 1080p60 DMD imagers. It effectively compacts two L/R views into a single frame by using a checkerboard pattern, only requiring a standard 1080p60 resolution for stereoscopic transmission to the TV. The
