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
Curvehas the coordinates of its points.A
Curveis defined as a one-dimensional geometry.A
Curveis simple if it does not pass through the same point twice.A
Curveis closed if its start point is equal to its endpoint.The boundary of a closed
Curveis empty.The boundary of a nonclosed
Curveconsists of its two endpoints.A
Curvethat is simple and closed is aLinearRing.
