◆ computePoint()
Computes a point of the curve, defined by the given parameter.
- At parameter 0, the point is the start point of the curve.
- 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. |
Implements luciad::Curve.

Returns the length of the semi-major axis of the elliptical arc.
If the coordinate reference is a geodetic reference, this is expressed in meters. Otherwise the unit of the reference is used.
- Returns
- the length of the semi-major axis of the elliptical arc.
◆ getB()

const |
Returns the length of the semi-minor axis of the elliptical arc.
If the coordinate reference is a geodetic reference, this is expressed in meters. Otherwise the unit of the reference is used.
- Returns
- the length of the semi-minor axis of the elliptical arc.
