- Circular interpolation controls two or
more axes so that the start point and
the end point (target position) are
connected with circular arc.
- As there are innumerable number of
arc locus connecting two points, an
auxiliary point, the arc radius, the
center or the direction should be
specified in addition to the start point
and the end point to determine the
circular arc.
