The dongle usually also drives a pair of LCS glasses. The video signal will then be an alternating sequence of left and right "frames". In the first frame it blacks out the odd numbered lines, and in the next frame it blacks out the even numbered lines, and this sequence then repeats. The dongle actively blacks out alternate lines of the video signal. A dongle plugs into the VGA port of the computer and the monitor plugs into the back of the dongle. you don't need a high speed video card to display flicker-free stereoscopic images.Ī row-interleaved 3D image is displayed by the video card in progressive-scan video mode (i.e.

software is relatively simple (apart from compatability with GUIs).

images need to be squashed vertically before writing to video memory.

Software needs to be smart to maintain compatibility with existing graphical user interfaces (like Windows).

With these images to allow you to see a 3D image. So again, there will be left and right images being displayedĪlternately (time sequentially).

Sync Doubling (or sub-fields) works by dividing your existing screen

very easy to display stereo images by using 3D interlaced images (such as appropriately generated gifs).

relatively simple software-wise to implement.

Some video cards won't switch to interlace mode.

Rate, each eye will see a different image. When viewed through LC shutter glasses synchronised with the field Then the left image will be displayed (left and right images willīe alternately displayed - time or field-sequentially).

Of odd lines from the right perspective image and the even linesįrom the left perspective image, the interlaced nature of theĭisplay will mean that first a right image will be displayed and On the screen (the odd field) and then the even lines of the imageĪre drawn on the screen (the even field). Interlacing means that first the odd lines of the image are drawn field-sequential DVDs and VHS video tapes available from various suppliers). Interlacing is probably the easiest method and is what is used in (PAL and NTSC) 3D video Row-Interleaved Image + Interlaced Display Glasses hardware can be relatively simple.Your video card memory will need to accommodate two images (the left and right) to allow the page flipping to occur.

Your video card needs to support page flipping in the BIOS, or you need a resident device driver to do the page flipping.

The result is a sequence of left perspective image and right perspective image frames.

The flipping can be performed by your video card's BIOS (the better solution) or a device driver could be installed which will watch the progress of the videoĬard generating the video signal. One 'page' will hold the left perspective image and the other 'page' will hold the right perspective image. Page flipping works by flipping between two pages of video memory (of the videoĬard) every time a new image (frame) is to be displayed. It is primarily used with non-interlaced (or progressive scan) displays (which display all the lines of the frame in one go, not half/half as in interlacing). Page flipping is the highest quality method of producing time-sequential stereoscopic display. Here's a quick tutorial if you are interested how these systems work:

There are four main techniques of achieving time-sequential display with PC systems. This is called variously time-sequential, field-sequential, frame-sequential, or image-sequential. LCS 3D glasses rely on a sequence of alternating left and right images displayed on a monitor. (NB: LCD monitors are generally not compatible with LCS glasses - see below). One common 3D viewing technique is to use a pair of Liquid Crystal Shutter (LCS) 3D Glasses in combination with a CRT monitor. A large range of hardware and software is available to allow you to view stereoscopic 3D images on a PC.
