tridimensionnelles

Tridimensionnelles is the feminine plural form of tridimensionnel, meaning "three-dimensional" in French. It designates objects, representations or analyses that possess three spatial dimensions: length, width and height (depth). The term comes from tri- (three) and dimension, from Latin roots.

In geometry and mathematics, tridimensionnelles describes solids and figures in space, such as cubes, spheres or pyramids. In common usage, it denotes anything with depth or with depth cues in a visual context, including three-dimensional images and models.

In technology, design and industry, the expression applies to three-dimensional modeling, rendering, computer graphics, architecture, product design and manufacturing. Three-dimensional models, digital sculpting, virtual environments and three-dimensional printing all rely on tridimensionnelles representations to guide fabrication or visualization.

In imaging and medicine, imagerie tridimensionnelle refers to 3D reconstructions from CT, MRI or ultrasound data, providing volumetric views of anatomy or structures.

In art and sculpture, tridimensionnelles works emphasize mass, volume and space, contrasting with flat two-dimensional surfaces. The term is common in technical contexts as well as in popular language to describe objects or scenes that convey depth.
