This file is a stereogram. Stereograms are stereoscopic images or animations which combine left and right frames showing slightly different visual angles to allow for 3D perception.
The stereogram uses the side-by-side method. It has not been indicated which frame shows which eye's respective angle. It is either unknown or the image is made to be usable with both parallel and cross viewing. (If the image is not intentionally reversible, please correct this template by changing the first/method parameter to either "parallel" or "cross".) It might be possible to view this image without a viewing device by either diverging or crossing your eyes to visually combine the frames, or a stereoscope may be used. |

Summary
[edit]
| Description |
English: Stereogram panels for testing stereoacuity. An improved version of the Stereo Snellen chart created by wikipedia user Gwestheimer. In this chart, each line has one letter closer in depth and another further in depth. The magnitude of the disparity decreases from top to bottom (top being the largest differences in depth). The "correct" differences when viewed with parallel free fusing (p) or cross-eyed free fusing (x) are:
Row 1 (top row): O (p: further, x: closer), T (p: closer, x: further) Row 2: P (p: further, x: closer), L (p: closer, x: further) Row 3: K (p: further, x: closer), E (p: closer, x: further) Row 4: R (p: further, x: closer), T (p: closer, x: further) Row 5 (bottom row): C (p: further, x: closer), B (p: closer, x: further) |
