  A mesh is a data structure containing vertex vectors, normal vectors and
index triplets which tell which vertices form triangles.
  From the point of view of the user, a mesh is a collection of free
triangles.
  A mesh is an object.

  A wireframe is a way of representing a surface (*any* surface) by using
line drawing.
  A mesh can be drawn easily as a wireframe (by drawing a line for each
edge of each triangle), but that doesn't make wireframes exclusive to
meshes. All surfaces can be represented as a wireframe (it's only a
question of how easy or difficult it is). Many other surfaces can also
be rather easily drawn as wireframes.
  A wireframe is basically an image, a visualization.
