A mesh is basically a whole bunch of triangles (known as "facets" iirc). Each
edge of each triangle is shared by another triangle. When you see a figure in a
pov image, you can pretty much bet that it's a mesh, probably consisting of
several thousand triangles.

It's rare to use them for inorganic shapes, since, by and large, such shapes can
be modelled more effectively using primitives and CSG, but trying to model
something like a horse or human using standard pov primitives would be a
nightmare.

Generally, users don't write their own meshes, but will convert them from, for
example, exported poser figures. (poser can't export a mesh directly, but it can
export intermediary formats for which converters exist - iirc there is now a
converter that can handle poser format files directly).
