What is 3D mesh in 3D modeling 3D generation?

In 3D modeling and generation, a 3D mesh is a framework of vertices, edges, and faces that defines the shape of a 3D object. - Vertices: Individual points in 3D space—they’re the basic building blocks. - Edges: Lines connecting vertices, forming the mesh’s “skeleton.” - Faces: Surfaces (usually triangles or quadrilaterals) that fill gaps between edges to create a visible shape, used for game assets, animations, or 3D prints. For beginners, editing a simple mesh in tools like Blender (e.g., moving vertices or adding faces) makes how meshes form 3D objects tangible.
