Curve is a one-dimensional geometry,
usually represented by a sequence of points. Particular
Curve define the type of
interpolation between points.

Curve is defined as a one-dimensional
Curve is simple if it does not pass
through the same point twice.
Curve is closed if its start point is
equal to its endpoint.
The boundary of a closed
Curve is empty.
The boundary of a nonclosed
consists of its two endpoints.
Curve that is simple and closed is a
