Detailed Description

An ElevationCurveData for road elevation profiles.

Predefined types for roads.

Used for drawing and managing roads.

Enumerator:

ROAD	Basic road.
UNKNOWN	Undefined.
BRIDGE	Bridge linking 2 roads, passing on top of another.

proland::RoadElevationLayer::RoadElevationCurveData::RoadElevationCurveData	(	CurveId	id,
		CurvePtr	flattenCurve,
		ptr< TileProducer >	elevations
	)

Parameters:

	id	the id of the curve for which we need to store the data.
	flattenCurve	the flattened version of the curve for which we need to store the data.
	elevations	the producer used to compute raw terrain elevations, themselves used to compute the elevation profile.

proland::RoadElevationLayer::RoadElevationCurveData::~RoadElevationCurveData ( )

virtual float proland::RoadElevationLayer::RoadElevationCurveData::getAltitude ( float s ) [virtual]

Returns the height corresponding to the given s coordinate.

Parameters:

s

a pseudo curvilinear coordinate (see Curve::Vertex::s).

virtual float proland::RoadElevationLayer::RoadElevationCurveData::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.
	path	the Curve to compute the cap length from. Must contain p & q.

Reimplemented from proland::CurveData.

virtual float proland::RoadElevationLayer::RoadElevationCurveData::getEndHeight ( ) [virtual]

Returns the height of the ending point of the curve.

virtual float proland::RoadElevationLayer::RoadElevationCurveData::getStartHeight ( ) [virtual]

Returns the height of the starting point of the curve.
