Welcome to the 3-DVG Home Page
Dear Visitor
This site will expose you to a novel 2-D to 3-D visual
display process that creates a surprising 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.
3-DVG Initiation Model in use
The 3-DVG effect has been routinely called, "unbelievable", "incredible", and basically, " must be seen to be believed". See the Customer Comment page.
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 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.
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

For vision science experimenters, the 3-DVG Resource Document is a collection of articles and references on the 3-DVG and other 2D to 3-D effects. The document argues that the 3-DVG effect is the visual summation of four independent 2D to 3D visual effects that include the pinhole effect, the Ames effect, pinhole generated chromostereopsis, and illocal framing. The resource document 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.
