History of the 3-DVG Invention

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.

Complementary 3-DVG initiation training devices were provided to interested persons in the visual sciences and details on how to implement the 3-DVG visual process using "two ordinary business cards" were provided freely on the Web from 1998 to 2008.
