The building blocks of a polygon mesh in 3D models are vertices, edges, and faces—these three core elements form the mesh’s fundamental structure.
Vertices: Individual 3D coordinate points (x, y, z) that act as the mesh’s anchor, defining its position in 3D space.
Edges: Straight lines connecting two vertices, serving as boundaries between faces and providing structural framework.
Faces: Closed polygons (most commonly triangles or quads) formed by connecting three or more edges, which create the mesh’s surface and visible shape. Together, these components shape the mesh’s geometry and detail.
