First of all, what is a stereogram? A stereogram is a 2D picture, which hides a 3D image behind it.

There are three main steps in the process of stereograms' creation:

■ Step 1 - creating or importing of a depth map. Usually the depth map is a grey-scale picture of the 3D object, that shows how deep each part of the scene is (dark shades - distant areas, lighter shades - nearer areas).

■ Step 2 - creating or importing a texture. The texture is a repeating pattern, used for "covering" the real picture behind a mosaic.

■ Step 3 - creating the stereogram (also known as SIRDS, SIS etc.).

This website contains information about how the stereograms are made and offers you the opportunity to make them yourself using the resources from the Downloads section.

You also may learn how to see the stereograms, and may train you eyes visiting our large gallery of 3D images.

ENJOY!
