The Shroud image encodes 3D information that reflects the distance between the cloth and the body it wrapped — the same principle of extracting topographic data from image density that NASA applies to map planetary surfaces. The image maintains consistent color throughout, with lighter areas containing fewer pigment deposits per fiber and darker areas showing more concentrated deposits. This encoding technique, which allows conversion to a 3D relief map, was not reproducible by known medieval artistic methods and was not duplicated until the 20th century.
Shroud Image Encodes 3D Information Like NASA Topography

Key facts
- The Shroud image encodes 3D information in the same way NASA maps planetary topography
- The image uses the same color throughout, with density variation creating light and dark areas
- Lighter areas have fewer pigment dots per fabric space; darker areas have more concentrated dots
- NASA uses this same principle to encode 3D topography from images of distant planets
- The image can theoretically be converted into a 3D representation
- This technique is not possible with basic photography
