Member Function Documentation

virtual float proland::CurveData::getCapLength	(	NodePtr	p,
		vec2d	q
	)			[protected, virtual]

Computes the cap length at a given extremity.

Parameters:

	p	the Node from which to compute the cap length.
	q	a point determining the direction of the cap length.

Reimplemented in proland::RoadElevationLayer::RoadElevationCurveData, and proland::WaterElevationLayer::WaterElevationCurveData.

float proland::CurveData::getCurvilinearCoordinate	(	float	l,
		vec2d *	p = NULL,
		vec2d *	n = NULL
	)

Computes the pseudo curvilinear coordinate corresponding to the given l coordinate.

Parameters:

	l	a curvilinear coordinate (see Curve::Vertex::l).
	p	where to store the x,y coordinates corresponding to l, or NULL if these coordinates are not needed.
	n	where to store the normal to the curve at l, or NULL if this normal is not needed.

float proland::CurveData::getCurvilinearLength	(	float	s,
		vec2d *	p = NULL,
