Abstract
StereoGraphics Corporation has over a decade of experience providing stereoscopic display products for use with UNIX workstations and has become the leading vendor in that marketplace. To achieve this kind of marketplace acceptance, the company had to go to great lengths to solve a myriad of interface issues that arose because of a lack of standardization. More recently, the company developed and marketed a PC product that operates under DOS and Win95. This product specifically solves the problem of using shuttering eyewear for a flickerfree result when used in conjunction with non-stereo-ready video boards, i.e., those that do not operate at a high field rate. With the growing acceptance of WinNT workstations in applications such as mechanical CAD, a design effort was undertaken to create a new family of products that would prove ease of interface with this new workstation infrastructure. This paper describes the development of StereoGraphics products designed specifically for the WinNT workstation. The interface task is greatly simplified for machines employing video boards which include quad buffering, operate at a high field rate and use the VESA Standard Connector for Stereoscopic Display Hardware. The new products include: An infra-red emitter compatible with CrystalEyes, low cost wired shuttering eyewear of high optical quality,an d an emitter that will work with non-stereo-ready video boards. In addition, the company's polarization modulator, the ZScreen, which uses passive eyewear, also interfaces with the new NT infrastructure.
