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 aLinearRing
