A bit more than that, here's the patent:

It's in 'patent' language but the concept is there :)

Hey Ahmidou !
Getting some neighbors and averaging ?

Yes exactly, but it's patented by AD, so
you'll need to roll you own

Makes sense ! That's what the "smoothed
surface" button compensate for in XSI ?

Hmm, I think that's to be expected. The
edges and points are generally closer to
the grid than the faces. Think of it as
you've started with a perfect sphere
made of wood, and you just sanded it
down to get those flat triangles. The
edges and points represent the places
that haven't been sanded down, so
therefore, generally, they're closer to
the grid than the flat surfaces.

The Attribute Transfer is nice to
prototype an idea, but it's rather slow
(unless they rebuild it since I used
it) compared to the execution speed of
a Vop Sop.
In Vop Sop, I use the PcOpen + Pc
Filter to mimic the Attribute Transfer
at God speed :)
While we're speaking of the xyz+PrimUV,
I found it has a weird behaviour
compared to the ClosestLocation of ice.
Here's a screen shot of what I have :

Basicaly a Grid emit some particles
with a Pop solver, I build a PopVop to
create a Velocity(v) that make the
particles going from their position
toward the closest UV location on the
Sphere.
If you look at the screenshot you can
see that the location has some
preferences for the points and edges
rather than the polygons area.
Have I missed something ?

Take a look at the "primuv" and
"xyzdist" VEX functions. They allow
you to get near identical behaviour
to closest point look ups. It's not
too much work to wrap them up into
reusable HDAs. (In fact, I'd
recommend doing it as a good way to
start getting your head around HDA
creation as a process.)

Strange thing you describe here.
I’ve found that most advice comes
in the from of using the Attribute
Transfer SOP.
