18.2.4. Class Curve

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 non-instantiable 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.

  • 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 non-closed Curve consists of its two endpoints.

  • A Curve that is simple and closed is a LinearRing.
