StereoGraphics is the worldwide leader in 3D stereo visualization products and prototyped the first flickerless field-sequential electro-stereoscopic display in 1981. CrystalEyes, introduced in 1989, were the first untethered liquid crystal 3D glasses. CrystalEyes are used extensively on workstations for molecular modeling, CAD, geographic information systems, corporate presentations and scientific visualization. SimulEyes VR is StereoGraphics' adaptation of this technology for the mass market. The StereoGraphics Developer Program provides information necessary to produce quality stereo-vision software applications including games, multimedia, molecular modeling, CAD/CAM, etc. through the Software Developer's Kit and the StereoGraphics Handbook (a guide to creating exceptional stereo images). Software developers can tap into the knowledge we've gained in our 16 years in the 3D visualization industry. Our program offers developers the support they'll need to produce 3D stereo-vision software with exceptional visual effects and realism. After all, we wrote the book on good stereo-literally. And that's information we pass on to our developers. StereoGraphics eyewear products do not require the user to open the PC, install circuit boards, set dip switches, interrupts or jumpers, or load device drivers. Installation is entirely external and so simple it takes only a few seconds. This simplicity results in a product that is truly plug and play. SimulEyes VR StereoGraphics Corp. SimulEyes VR shuttering LCD glasses provide true stereoscopic 3D viewing to multimedia and game users. The effect is amazing: The surface of the screen disappears and images occupy the true three-dimensional space. The PC user can experience true 3D on a PC for under $100 with SimulEyes VR. No other stereoscopic viewing device offers the comfort, resolution and ease of installation of SimulEyes VR, all at an affordable price. The video boards used in multimedia PCs conform to the IBM 8514 1024 by 768 standard, an interlaced format operating at approximately 90 fields per second. SimulEyes VR takes full advantage of this high field rate. Most products that operate at a lower field rate have noticeable flicker. At SimulEyes VR's high rate, flicker is practically imperceptible. And for non-interlaced DOS games, page swapping offers an excellent fast action mode at 70Hz and 80Hz. Converting and developing code for SimulEyes VR is surprisingly straightforward. Since 3D stereo emulates the way your eyes work, it requires two perspectives , one for the right eye and one for the left. To differentiate the left and right images, a line is inserted on the last pixel row (a short line indicates the left image, and a long line indicates the right eye view), a method called the "White Line Code". The White Line Code then triggers the eyewear shutters so that the appropriate shutter opens for the appropriate eye while the opposite shutter is closed. A logic circuit ensures that only bona fide code will trigger the eyewear. CrystalEyes StereoGraphics lightweight CrystalEyes eyewear are designed for untethered 3D Stereo visualization on computer monitors, displays and large-screen projection systems. CrystalEyes provide high-resolution, realistic and flicker-free stereo viewing for scientific visualization, CAD, molecular modeling, corporate presentations, GIS, virtual environments and many other applications. CrystalEyes incorporate liquid crystal shutters that alternate between transparent and opaque at 120 frames per second, synchronized with a 120 Hz stereo-ready monitor using an infrared signal. When the left image is displayed, the left lens of the eyewear opens while the right lens closes-displaying the correct image to the correct eye. The result is a non-flickering, full-color, true stereo 3D image, replicating the way people view their surroundings in the real world. Because CrystalEyes glasses are sycronized with the displayed 3D stereo image via an infrared signal, any number of users can simultaneously view the display with complete freedom of movement. CrystalEyes are available with or for most major stereo-ready workstations and personal computers. Platforms include Silicon Graphics, Sun, Digital and Hewlett Packard. It also runs on IBM-compatible PCs, Macintosh and NEC. And all the major monitor manufacturers produce stereo-ready monitors. Crystaleyes Software Development CrystalEyes development on workstation platforms is a straightforward process. Nearly all SGI hardware systems built in the last five years (and all systems currently shipping) include built-in hardware support for CrystalEyes. Many other workstations also include CrystalEyes support right out of the box. Using industry standard Open GL, a developer can take advantage of special extension functions to create stereoscopic applications. These functions enable the developer to check whether the hardware is stereo-ready, easily switch into and out of stereoscopic display mode, and draw to either or both of the eye buffers. And platforms that don't use Open GL generally have their own set of built-in stereo functionality. |
