Other systems can only display stereo in the front of the dome. E&S' exclusive technology and partnerships provide show producers with powerful software to create pre-rendered 3D scenes that jump off the screen in every direction, for an unforgettable experience. Supported 3D Display Methods Anaglyph This method for displaying 3D imagery on the dome uses a single set of projectors. The projected image contains a composite of left eye and right eye information overlayed together. The left eye image is tinted one color and the right eye image is tinted another color. Using inexpensive glasses with color filters, the left filter cancels the right image only allowing this eye to see the left eye information and vice versa. In this way both eyes combine to see 3D; however the color palette is greatly reduced and brightness drops by over 50%. %. Every Digistar system is capable of presenting Anaglyph stereo with real-time computer graphics: all that is needed is a number of inexpensive cardboard glasses to see this stereo effect. It is a great way to show investors the potential of fulldome stereo without going to the expense of purchasing a theater-quality stereo fulldome system. INFITEC 3D This method uses two sets of projectors to display the 3D image. One set of projectors displays the left eye image and the other displays the right eye image. Using a set of filters in the projectors, the left eye image shows the lower frequencies of the RGB colors and the right eye image shows the upper frequencies of the RGB colors. Filters in the passive (non-electronic) glasses cancel the right image in the left eye and vice versa. The combined images re-join both halves of the RGB colors, providing full color fidelity and the full brightness of a single set of projectors. This method allows a minimum number of blends between projectors in the dome, since the two stereo projectors in the back of the theater are overlayed to cover the entire front half of the dome, and the stereo projectors in the front of the theater are overlayed to cover the entire back half of the dome. This creates one blend between both sets of projectors across the top of the dome. Active Stereo This method uses one set of projectors to display video that runs at over twice the normal frame rate. Left and right eye imagery is either interleaved on every other frame and displayed in one video stream, or combined from two separate (left and right) video streams. Glasses with LCD shutters that are timed to the frame rate of the video, blank one eye at a time with refresh rates up to 120 Hz to produce stereo imagery. This technique offers full color fidelity at about 50% brightness. A second set of projectors can be added for even higher brightness, or high brightness projectors can be selected so that a second set of projectors is unnecessary. Glasses contain electronics and batteries but still can be machine washed. There are a number of ways to present active 3D stereo in the dome. One way to do it is to have 60 fps video with interleaved stereo imagery in the video stream (every other frame is left/right); this results in 30 fps for each eye. This technique will produce a stereo image, but there is a bit of visual strobing, and can cause eye strain in some people. This technique works best using JVC or DLP projectors. Certain DLP projectors (both 2K and 4K resolution) can run at 120 Hz active stereo for a full 60 fps per eye. This is the ideal and preferred way to present active 3D stereo in the dome. Technical Considerations Spherical 3D® realtime processing capability is included with every Digistar. Digistar software natively supports all listed stereo display methods. Anaglyph Stereo and Active Stereo require only one set of video projectors. Refresh rate of active stereo may be limited by video projectors. INFITEC 3D Stereo requires a second set of video projectors. Micoy 3D is pre-rendered into fulldome video, and must be prepared specifically for Anaglyph, INFITEC 3D, or Active Stereo presentation. Please specify the desired display system format when licensing 3D shows. Anaglyph glasses are available in inexpensive cardboard frames with plastic lenses, or in plastic frames that can be machine washed INFITEC glasses use passive technology. They are machine washable and are available in a variety of lens sizes in plastic frames. Active Stereo glasses are available in plastic frames with electronic components built into the glasses themselves. These glasses are also machine washable. Because 3D glasses reduce image brightness, CRT projectors may be too dim for 3D effects to display properly. These specifications are subject to change as new technology becomes available.
