Stereopaari

Stereopaari is a term used in Estonian to describe a pair of stereoscopic images or a stereoscopic view. It refers to the principle of creating the illusion of depth from two slightly different perspectives, mimicking how human binocular vision works. This technique is commonly employed in various forms of media and technology to achieve a three-dimensional effect.

The creation of a stereopaari involves capturing two images of the same scene from slightly offset viewpoints. These viewpoints are typically separated by a distance similar to the interpupillary distance of a human eye. When these two images are presented to the viewer in a way that each eye sees only its corresponding image, the brain fuses them to perceive depth and a sense of three-dimensionality.

Stereopaari can be experienced through various methods. Traditional methods include anaglyph 3D, which uses color-filtered glasses (typically red and cyan), or parallel viewing and cross-eyed viewing techniques where the viewer's eyes are directed to converge or diverge in a specific way. More modern applications utilize polarized 3D glasses, often seen in cinemas, or active shutter 3D glasses used with compatible displays. The underlying principle remains the same: presenting two distinct images that, when viewed correctly, create a stereoscopic effect. This technology has applications in photography, filmmaking, virtual reality, and scientific visualization.
