Say I have a regular surface like a box, is there an easy simple way to just
smooth and round off the edges?

Thanks

  Do you mean that you have a box as a *mesh*?

  If so, then I think this might be what you are looking for:

Thanks, I'll give it a go.

Not terribly useful in its present form.  I'm working on an update.
In any event, subdivision surfaces are not intended for smoothing
the edges of polyhedrons, but rather are for designing organic shapes.

Is it possible to use your algorithm for making smooth transition
from trunk to branch, from branch to twigs in mesh trees saved
from POV-Tree? I think the most difficult part is to find intersections
because for example branches and trunk are separate meshes.

The macros take a hull that has already been designed, and refines it
by replacing each face with a set of smaller faces.  The edges are
divided and the orginal points are moved slightly as well.  When this
is repeated a few times, the result is a curved surface.  With the
right hull, you can make almost anything.

For a tree macro, the macros should be fed a rough hull of the tree
(which is fairly easy to build); the marso would then make a smooth
tree.

John

A better word than "smoothing" in this case would probably be "bevelling".
If you're working with CSG, this one seems very useful:

If you're working with meshes, I suggest using a modeller because it gives
me much more flexibility than coding. Try Wings3D, it's freeware, powerful
and really user friendly:
