A 3D Model is a digital representation of a three-dimensional object or environment constructed from vertices, edges, faces, and materials, encoded in standard formats such as glTF, OBJ, FBX, or USD, and used as a foundational asset in spatial computing, simulation, gaming, and metaverse applications.

Overview
3D Models form the visual foundation of immersive experiences, ranging from simple geometric primitives to complex character rigs with hundreds of thousands of polygons. Each model is composed of geometric data (mesh), material properties, and optional skeletal rigging for animation.
Components
-
Geometry: Vertices and faces forming the visible shape
-
Materials: Surface properties including colour, roughness, and metallic values
-
Textures: 2D images applied to surfaces for visual detail
-
Rigging: Skeletal structure enabling animation and deformation
-
LOD Variants: Multiple detail levels for performance optimisation
