[Note]
：
dVd
is
defined
as
the
height
of
the
second
point
minus
the
height
of
the
first
point.
Due
to
this
reason
dVd
can
be
negative.
dSd
is
defined
as
the
length
of
the
missing
line.
dHd
is
defined
as
the
length
of
the
projected
missing
line
in
the
horizontal
plane.
dSd
and
dHd
are
always
positive.
