Frequently Asked Questions

How does a standard DLP work?

For more information, visit the Texas Instruments DLP Technology website.

Do I have to use a ViSaGe or Bits# with the DepthQ 360?

No. You can use almost any computer graphics system in any computer. The graphics systems needs to be about to produce analogue RGB video: 1280x720 @ 120Hz. Most graphics cards still have a VGA or DVI-I output so you just need an apropriate cable. If you have a pure digital HDMI or DisplayPort output then you will need an active converter to produce analogue video on an HD15 VGA conector.

Why might I want to use a ViSaGe or Bits# with the DepthQ 360?

If you need to produce accurate stimulus synchonous TTL-compatible triggers or switch active shutter goggles in alternate frame stereoscopy (or other binocular vision experiments) then the ViSaGe and Bits# hardware have special features which will allow you to output the control signals at the appropriate times (e.g. at the onset of each sub-frame, within the 100 microsecond dark period).

Do I need special software to format my video frames for use with the DepthQ 360?

No. The greyscale encoding system is simple and easy to understand. Instead of creating bitmap frames by thinking of three colour channels, one each for the Red, Green and Blue values for each pixel, just think of the Red channel as encoding sub-frame A, the Green channel as encoding sub-frame B and the Blue channel as encoding sub-frame C. All three channels/sub-frames are sent to the projector as normal, but they are output individually at three times the usual rate.

Can you provide any demo software?

Yes. We have coded an example rotating wedge stimulus using the Psychtoolbox-3 extensions for MATLAB.
