Simple Method on How to View 3D, Stereographic Images Using the Cross-eyed Method. |

Using this method may help
relieve eye strain that causes some people to feel queasy when using the cross-eye method
to view Stereographic images without the use of a mechanical viewer. Per the diagram below, take a sheet of 8.5 x 11 inch paper (A4) and cut it in half so the you have two pieces of paper, each measuring 8.5 x 5.5 (210 x 148.5 mm). Facing the monitor that is displaying the dual image for cross-eyed viewing, hold the two pieces of paper vertically, one in each hand, in front of your face, about 5.5 inches (14 cm) from your eyes. Each piece of paper should be separated by about an inch and a quarter (3 cm). Look at the inside edge of the paper in your right hand. Most likely it will be out of focus. Now, ever so slightly, shift you vision to the image on the monitor. You should see the two image combined into a 3D one. You may have to adjust the open distance between the two pieces of paper so the you see just the 3D image. Henceforth this will be refereed to as the "Dipapyri Method" for viewing cross-eyed stereographic images. |
