Mesh model

A mesh model is a type of 3D model that represents the shape and surface of an object using a collection of interconnected polygons, usually triangles or quadrilaterals. The mesh consists of vertices, edges, and faces that form a geometric network, allowing for detailed representation of complex forms and surfaces.

Mesh models are widely used in visualisation, simulation, animation, virtual reality, gaming, and 3D printing. They are especially useful for rendering photorealistic surfaces and organic shapes in digital environments.

Meshes can be created from scratch using CAD software, or generated from reality capture methods such as laser scanning or photogrammetry. In engineering and industrial contexts, mesh models support clash detection, virtual assembly, and real-time interaction with digital twins. Although mesh models are less structured than parametric or solid models, they are efficient for visual representation and performance in interactive applications.
