What component of a GameObject does a mesh represent?

A mesh represents the geometric data of a GameObject, including vertices, normals, and potentially other attributes such as UV coordinates. This geometric data defines the shape and structure of the object within the 3D space of your game, allowing the rendering engine to draw it accurately. When you manipulate a mesh, you're working directly with the fundamental outline of the model, which is critical for how it interacts visually and physically within the game environment. The mesh does not account for textures, sounds, or scripts associated with the GameObject; those are handled by separate components that contribute to how the mesh is visually rendered and how it behaves within the game. Hence, understanding that a mesh primarily concerns the 3D geometry is essential for grasping the overall structure of GameObjects in Unity.
