A mesh is by definition a group of triangles ranging in numbers
from 2 to many thousands or millions. They are commonly used
to make complex shapes that spheres and other pov shapes either
can't make in combinations or would be prohibitavly difficult to
make. Objects that are a good candidate for meshes are car bodies,
faces, animals, etc. Unfortuantly it nearly impossible to model
by hand with triangles but there are many external modeling programs
that will allow you to model a shape and then export to a Pov mesh
object. Triangles used to use a union for this but the memory usage
was very ineffecient and even more so if more than 1 union of the
same object was used. The programmers optimizes the program to allow
you to declare one mesh of objects, place several in a scene, and use
only as much memory as you would for one. There is a bit more because
textures for each object add to it but it is not as much memory used
as unions of triangles consumed.

Got it ?
