Member Function Documentation

computePoint()

Coordinate luciad::BezierCurve::computePoint ( double  parameter ) const

overridevirtual

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.

Implements luciad::Curve.

getBounds()

Bounds luciad::BezierCurve::getBounds ( ) const

overridevirtual

Returns the bounds for the geometry object.
