A mesh is a collection of vertices (points in 3D space), edges (lines connecting two vertices), and faces (polygons formed by three or more edges, typically triangles or quads). Meshes are the most commonly used object type in Blender and serve as the basis for 3D modeling, animation, and rendering. They are versatile and can represent a wide range of objects and surfaces by manipulating their geometry.
