3.10 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 in order to be displayed and interpreted correctly in a typical stereo 3D
viewing environment.
3.10.1 3D Description
In simple terms, 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).

3.10.2 What Do I Need for 3D?

The CP2000-SB requires a 3D-capable SMPTE source and a few special hardware/software setups described
here. Essentially you will connect two signals (one left eye, one right eye) to the projector, then use the TPC's
Custom: 3D Control menu options to define and control the signal processing, synchronizing and output for
devices used in your stereographic 3D display. These settings ensures critical ordering and timing of the
incoming L/R frames so that they merge correctly into a convincing artifact-free 3D display without cross-talk,
ghosting or other artifacts.

System Requirements

• CP2000-SB projector. Includes all standard 3D components:
• FFIB (FPGA Formatter Interface Board):
• TPC software v2.3c or higher
• Main projector software v8.0 or higher
• Two HD-SDI cinema signals (left and right) connected to the projector's SMPTE ports A and 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
• 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
(Accessed from within the pedestal-refer to
