3-DVG Home Page

This site will expose you to a novel 2-D to 3-D visual display process that creates a surprising and stunning 3-D stereoscopic display from ordinary two-dimensional color photographs printed in any magazine. The fun part about this process, called the 3-DVG effect, is that a major portion of it, once learned, can be implemented using only your fingers. And the super good new is that you are possibly no more than fifteen minutes away from actually experiencing this new visual phenomenon.

The 3-DVG effect has been routinely called, "unbelievable", "incredible", and basically, " must be seen to be believed". And remember, we are talking about any color picture from any magazine although scenic pictures from National Geographic magazine work best because of their size and overall quality.

		Using only your fingers and a bit of practice, the 3-DVG effect will produce a perfect 3-D stereoscopic image, only miniature in size because you are standing four feet away or greater from the picture.
		Using the advanced 3-DVG optical device with variable pinholes and matched optical frames, the 3-DVG effect will produce a 3-D image that rivals a View Master, in spite of limited actual stereopsis and a less than ideal field of view.
		A properly adjusted advanced 3-DVG device can give a person the momentary but distinct impression that they are looking out of a window at the actual scene depicted in a magazine picture.

The invention itself, called the 3-DVG, or Three-dimensional Viewing Glasses (U. S. Patent 4,810,057), consists of simple pinhole devices that implement the 3-DVG method of generating 3-D (i.e., stereopsis). The 3-DVG effect was discovered by Kenneth J. Dunkley in 1985 and recognized as a unique visual phenomenon, i.e., the Dunkley Effect, by Professor Bela Julesz in 1989. The discovery of the 3-DVG effect grew out of a study of the differences between pictures and holograms..

The 3-DVG invention was highlighted in the March/April 93 of Stereo World magazine and again in the Nov./Dec. 1994 issue. The SPIE Proceedings also hosted a paper on the device in 1993.

The 3-DVG Visual Self Test [Dividing Line Image]

Take the 10 minute Visual Self Test to see if you can detect the 3-DVG phenomenon. Once detected and learned, the 3-DVG effect allows you to make any magazine photo appear in stereoscopic 3-D using only your fingers. Good luck on the test!

If you like what you see in the visual self test, the 3-DVG Initiation Model, utilizing optical quality metal pinholes, is now available. These units demonstrably improve the visual results and your chances of detecting the effect. See the Product & Ordering Information page.

The visual self test illustrated above uses holes made in ordinary business cards

How does the 3-DVG work? [Dividing Line Image]

The 3-DVG is a patented process that allow the integration of four previously known but heretofore unrelated 2-D to 3-D effects. The effects are (1) the pinhole effect, (2) the Ames effect, (3) pinhole generated chromostereopsis, and (4) illocal framing.

For vision science experimentalists The 3-DVG Resource Document is a collection of articles and references on the 3-DVG and other 2D to 3-D effects. The resource document explains the 3-DVG effect in gory detail and then goes on to show how all pictures can be perceived "in-depth" using only your normal natural vision. The information in this document can lead to a complete revision of your visual concepts regarding pictures.
