Working with 3D

A single projector can display 3D images as described below. Such images require a 3D-capable source as well
as additional hardware and cabling to correctly display and interpret in a typical stereo 3D viewing
environment. Images generated from a 3D-cinema source consist of a series of images (frames or fields) that
alternate quickly between two slightly different viewpoints corresponding to the physical separation of our left
and right eyes (called parallax). When these frames are displayed with enough speed and viewed with special
glasses synchronized with the left/right (L/R) frame sequencing, the resulting "single" perceived image
appears with much the same depth and perspective we sense in the real world. The new full resolution triple
flash hardware (Brilliant3D) includes an FPGA Formatter Interface Board (FFIB) which allows for full 2K
resolution using a 6:2 frame rate multiplication (Triple Flash). Triple Flash 3D is reference to a frame rate that
is of a high enough frequency to eliminate flicker as noticeable by the eye. The standard frame rate for most
2D D-Cinema content is 24 frames per second (FPS) as it is for film. For 3D, the server splits the 3D content
(video signal) into 2 interleaved signals of 24 FPS each by the server, for a total of 48 FPS input into the
projector. The projector's frame rate multiplication is set to 6:2, meaning the input frame rate is multiplied by 3
(Triple) for a total frame rate of 144 frames per second (Hz or FPS). For the Brilliant3D hardware, the TI DLP
version 13.1 or higher is required.
After connecting signals to the projector, use the web user interface Channel: 3D Control menu to define and
control the signal processing, synchronizing and output for devices used in your stereographic 3D display.
Refer to Section 3: Operation of the CP2000-ZX User Manual (020-100006-xx). These settings ensure
critical ordering and timing of the incoming left/right frames so they merge correctly into a convincing artifact-
free 3D display without cross-talk, ghosting or other artifacts.

3.6.1 Requirements for 3D

To display 3D, the CP2000-ZX requires a 3D capable SMPTE source and a few special hardware / software
setups as described below:
• CP2000-ZX projector (includes all standard 3D components)
• Two HD-SDI cinema signals (left and right) connected to the projector's SMPTE ports 292-A and 292-B.
NOTE: Use of a single input consisting of both left and right data is not currently supported.
• Sync output device:
• IR emitter for controlling the L/R gating (switching) of active glasses
OR
• Pi-Cell polarizer for controlling a screen that has a silver polarization-preserving surface for use
with passive glasses
OR
• Filter Wheel for controlling the spectrum of light for use with passive glasses
• Custom 3D sync output cable (GPIO) such as available from RealD:
• For routing the projector's output sync to your sync output device (connect from the projector's
GPIO to the emitter, filter wheel controller or polarizer). NOTE: The GPIO connector can be
accessed from the right side of the projector. Refer to Appendix C: GPIO of the CP2000-ZX User
Manual (020-100006-xx) for GPIO pinout information.
• Power supply for your sync output device, typically wired with the custom GPIO cable.
• Proper 3D configuration defined in the Channel: 3D Control menu. Use an internal test pattern for best
results.
