Dual Projector, Page Flipped 3D Guide

Microsoft's Flight Simulator X projected on a 10 foot wide panoramic wall screen. 3D glasses not shown in this photo.

Invented at 3D Flight Simulation Company

The world's first dual-DLP projector stereoscopic system was demonstrated on July 19, 2006 at the 3D Flight Simulation Company in Tinley Park, Illinois. 3D hobbiests around the world have since built numerous dual projector 3D systems using the design. Some pioneering gamers have even stretched the technology to build triple projector 3D platforms!

Many PC video games give excellent video on this 2048 X 768 pixel projection. The dual projector 3D system has been tested with Microsoft's Flight Simulator X, Aces High II, Combat FS3, Call of Duty, Trainz and Condor Competition Soaring.

Alternative Methods

With the introduction of 3D-Ready high definition televisions an alternative to DLP projection 3D is now available. One of the largest 3D-HDTV's on the market is the Mitsubishi WD-82737 (82 inches diagonal, or nearly 6 feet across). But at $3300 or more for this Mitsubishi gamers may still want to consider the dual projector design.

PARTS LIST

in this Dual-Projector 3D game room
 3DFlightSim is researching 3D-projector gaming for currently available PC hardware. For now the only guaranteed Dual-Projector 3D system uses older video technology. You will need:
  • A single core or dual core Windows XP gaming computer
  • An Nvidia 7950 or 7900 graphics card - or earlier model (for example, 6800 XT, etc.)
  • 3D-Compatible DLP projectors (See Andrew Woods List)
  • Nvidia V93.81 Stereo Driver (FREE from Guru3D)
  • Matrox DualHead2Go supporting Analog (VGA) monitors
  • Wireless 3D glasses and emitter kit
  • A PC 3D-Video Adapter AKA: PC "Dongle" (cheap!). Available Here
  • 3DFlightSim's Model 3D-1001 VESA booster/inverter
  • Stable and adjustable mounting for your 2 projectors
  • A BIG blank wall (or screen)!

Connection List

Cabling for Dual-Projector 3D

  1. PC "Dongle" - connects to Video Card VGA socket
  2. 3DFlighSim's model 3D-1001 Inverter
  3. Wireless IR Emitter for 3D Glasses
  4. Matrox DualHead2Go
  5. VGA cables, one for each DLP projector
(not shown: power supply for Matrox box)

Alignment

Aligning the two projector images to create a single panoramic image is not difficult. The seam between images is nearly unnoticeable. In addition, there is a very large space between beams where multiple viewers can sit without blocking the projector. This space proves to be much larger than you might expect.
