Tridimensionali

Tridimensionali is the Italian term used as an adjective to describe objects, spaces or representations that possess three spatial dimensions—length, width and height.

The word derives from Latin tri- ('three') and dimensione ('dimension'), and follows the standard Italian inflection: tridimensionale (singular) and tridimensionali (plural). It is used with nouns of any gender, for example, oggetti tridimensionali, spazi tridimensionali, modelli tridimensionali.

In mathematics and physics, tridimensionalità refers to three-dimensional space, usually depicted with three coordinates (x, y, z) and related concepts such as volume and surface area. In geometry, the study of three-dimensional figures includes polyhedra and solids.

In modern technology and media, tridimensionali commonly describe three-dimensional computer graphics and models used in design, animation and videogames, as well as rendering, virtual reality and augmented reality environments. 3D printing creates tridimensionali models by additive manufacturing from digital files.

In visual perception, tridimensional cues such as stereopsis, perspective and shading allow observers to infer depth from two-dimensional images. The term also appears in architecture, medical imaging and product design, where accurate three-dimensional representations are essential.
