Anaglyph is a term closely associated with 3D imagery and involves the combination of two separate images to create a stereoscopic effect. However, there are other synonyms that can be used to describe this effect, such as stereogram, stereo pair, and 3D image. Stereograms refers to a pair of images that are slightly offset and combined to make a 3D image. Similarly, stereo pairs involves using two separate images to create a greater sense of depth perception. Lastly, the term 3D image is simply the most general term used to describe any image that creates a three-dimensional effect. All of these terms ultimately refer to the same effect of creating a visual illusion of depth.
