stereoforms

Stereoforms are three-dimensional forms designed to be perceived with depth when viewed through stereo or binocular viewing methods. The concept emphasizes how form, perspective, and perception interact to convey volume and space, often leveraging binocular disparity and parallax. The term is used in several disciplines but lacks a universal definition or formal theory.

In sculpture and installation, stereoforms are commonly constructed so that two nearly identical viewpoints combine to yield a coherent depth impression when viewed with a stereo pair, anaglyph glasses, polarized projection, or other depth-enhancing methods. They may appear as complementary halves, as single objects designed for stereo viewing, or as arrangements that exploit shadows and translucency to reinforce depth cues.

In digital contexts, stereoforms refer to 3D models or scenes prepared for stereo displays such as VR headsets or autostereoscopic screens. Designers render two offset perspectives and manage occlusion and parallax to maintain depth without visual discomfort. The term is more often used descriptively in contemporary design discourse rather than as a formal technical category.
