3D model

A 3D model is a digital three-dimensional representation of an object, structure, or environment. It consists of geometry, such as points, lines, surfaces, and volumes, that defines the shape, scale, and spatial relationships of the represented entity.

3D models are used extensively in architecture, engineering, product design, the gaming industry, and animation. They enable detailed visualisation, simulation, analysis, and communication of designs before physical implementation.

3D models can be generated manually with CAD tools or automatically through methods like laser scanning or photogrammetry. They serve as the foundation for digital twins, virtual prototyping, and immersive technologies such as AR and VR.
