stereografií

Stereografií is a Czech term that translates to stereography. Stereography is a general term for any technique used to create the illusion of three-dimensional depth from two-dimensional images. This is most commonly achieved by presenting slightly different images to each eye, mimicking the way our natural vision works. The brain then combines these two images to perceive depth.

The most well-known application of stereography is in stereoscopic photography, also known as 3D photography. This involves capturing two images of the same scene from slightly different viewpoints, simulating the parallax between the left and right eyes. These images can then be viewed using various methods. Popular stereoscopic viewers, like those used in early 3D movies or simple cardboard glasses with colored filters (anaglyph 3D), separate the images for each eye. More advanced methods, such as lenticular printing or autostereoscopic displays, allow for 3D viewing without special glasses.

Beyond photography, stereographic principles are applied in fields like cartography, where stereographic projection is a method of mapping a sphere onto a plane. In computer graphics and virtual reality, stereography is fundamental to creating immersive three-dimensional environments. The core concept remains the same: presenting slightly altered perspectives to simulate depth and create a sense of volume. The term "stereografií" encompasses all these diverse applications of stereoscopic principles.
