Abstract: Given a smoothly embedded 2-manifold in
$\Rspace^3$, we define the elevation of a
point as the height difference to a
canonically defined second point on the same
manifold.
Our definition is invariant under rigid
motions and can be used to define features
such as lines of discontinuous or continuous
but non-smooth elevation.
We give an algorithm for finding points of
locally maximum elevation, which we suggest
mark cavities and protrusions and are useful
in matching shapes as for example in protein
docking.
