A Curve is a one-dimensional geometry, usually represented by a sequence of points. Particular subclasses of Curve define the type of interpolation between points. Curve is a noninstantiable class.
Curve Properties
A Curve has the coordinates of its points.
A Curve is defined as a one-dimensional geometry.
A Curve is simple if it does not pass through the same point twice, with the exception that a curve can still be simple if the start and end points are the same.
A 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 Curve consists of its two endpoints.
A Curve that is simple and closed is a LinearRing.
