So, faces? Well, just the one. Edges? Zero. Vertices? None. Oh dear! Oh well. The spheres are disappointed and one is angry. 3D shapes have faces (sides), edges and vertices (corners). Faces - A ...

or collections of vertices (points in 3D space), edges (lines between two vertices), and faces (polygons made of edges) to define an object. We can start building our thing by making a cylinder mesh.
