Function P = perpoffset(p,u,v,o)
P = perpoffset(p,pp,o)
returns points P after offsetting the input points p,
with a distance o, perpendicularily to the plane defined
by vectors u and v. Instead of input of u and
v directly, points pp may be given, from which is
calculated:
u = pp(2,:) - pp(1,:),
v = pp(end,:) - pp(1,:).
Input variable p has 3 columns and a row for each point;
the same applies to output variable P.
Input variables u and v are arrays of 1 row and 3 columns.
Input variable pp has at least 2 rows, and has 3 columns.
The validity of the input is not checked!
