Detailed Description

1-dimensional geometric primitive, representing the continuous image of a line.

One-dimensional geometries may be composed of simple curve segments where for adjacent curve segments the end and start point fall together to form a continuous geometry. A curve may be composed of curve segments that each have a different interpolation type. The most common use for curves is to have curve segments with the same interpolation type (e.g. polyline).

Member Function Documentation

computePoint()

virtual Coordinate luciad::Curve::computePoint ( double  parameter ) const

pure virtual

Computes a point of the curve, defined by the given parameter.

1. At parameter 0, the point is the start point of the curve.
2. At parameter 1, the point is the end point of the curve.

Parameters

parameter

the parameter value, within [0,1], to compute the point location for.

Returns

the computed point location.

Exceptions

luciad::InvalidArgumentException

if parameter is not within [0,1], or if the point could not be computed. For example, when the curve is defined by invalid points.

Implemented in luciad::ArcBand, luciad::BezierCurve, luciad::CircleBy3Points, luciad::CircleByCenterPoint, luciad::CircularArcBy3Points, luciad::CircularArcByBulge, luciad::CircularArcByCenterPoint, luciad::CompositeCurve, luciad::CompositeRing, luciad::Ellipse, luciad::EllipticalArc, luciad::Line, luciad::Polyline, and luciad::PolylineRing.

getLength2D()

virtual double luciad::Curve::getLength2D ( ) const

pure virtual

Returns the length of the curve.

Returns

the length of the curve.

Exceptions

luciad::InvalidArgumentException

if the length could not be computed. For example, when the curve is defined by invalid points.

Implemented in luciad::ArcBand, luciad::BezierCurve, luciad::CircleBy3Points, luciad::CircleByCenterPoint, luciad::CircularArcBy3Points, luciad::CircularArcByBulge, luciad::CircularArcByCenterPoint, luciad::CompositeCurve, luciad::CompositeRing, luciad::Ellipse, luciad::EllipticalArc, luciad::Line, luciad::Polyline, and luciad::PolylineRing.
