In 3D modeling, the term "mesh" refers to a network of interconnected vertices, edges, and faces that forms the structural framework of a 3D object, defining its shape, surface details, and volume in digital space.
- **Core components**: It consists of vertices (points), edges (lines connecting vertices), and faces (polygons formed by edges), which collectively build the object’s structure. - **Common polygons**: Most meshes use triangles or quads (four-sided polygons) as basic units, ensuring smooth rendering and editable geometry. - **Key role**: As the foundational building block, meshes enable detailed 3D design, animation, and physical realization via 3D printing.
In short, a mesh is the essential framework that brings 3D objects to life in digital and physical contexts.
