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.

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 ...
