stereoscopisch

Stereoscopisch, in English stereoscopic, describes imagery or perception that yields depth by presenting two slightly different views to the eyes. The brain fuses these views into a single three‑dimensional percept, a phenomenon known as stereopsis. Stereoscopische content is produced by capturing left and right images with a horizontal offset roughly matching human interocular distance, or by computer rendering to deliver two viewpoints.

Common display methods include passive polarized 3D, active shutter glasses that alternate images, and anaglyph techniques that encode depth in color. More recently, autostereoscopic displays aim to provide depth without the need for glasses. In photography, cinema, and scientific visualization, stereoscopy has been used to convey realistic depth and spatial relationships since the 19th century, with early devices such as the Wheatstone stereoscope paving the way for later 3D cinema and virtual reality.

Applications span entertainment (3D films and games), medical imaging and diagnostics, scientific visualization, and industrial design. In research and industry, stereoscopic data help measure geometry and depth, while in virtual reality and simulation it contributes to immersion and spatial accuracy.

Technical considerations include calibration of parallax, convergence, and the interaction between convergence and accommodation, which can cause eye strain for some viewers. Image quality may be affected by misalignment, crosstalk, or color artifacts in certain 3D methods. Well-designed stereoscopic content balances depth cues with viewer comfort and accurate depth perception.
