Think you meant to say vertical instead of horizontal as in hf aspects.
Perpendicular to the plane of the heightfield in other words. And I
believe you may be right about the unsmooth quality of such. Smoothing
goes from one pixel square to the next *across* the face of the hf, so the
vertical or perpendicular surfaces are always potentially a large distance
from each other the sharper the edge is.
Hmmm, and now that I've done said that... smoothing will go parallel to
the plane of the hf at least.
