Detailed Description

An ElevationGraphLayer for road graphs.

Constructor & Destructor Documentation

proland::RoadElevationLayer::RoadElevationLayer	(	ptr< GraphProducer >	graphProducer,
		ptr< Program >	layerProgram,
		ptr< TileProducer >	elevations,
		int	displayLevel = 0,
		bool	quality = true,
		bool	deform = false
	)

Creates a new RoadElevationLayer.

Parameters:

	graphProducer	the GraphProducer that produces the Graph tiles that this layer must draw.
	layerProgram	the Program to be used to draw the roads in this layer.
	elevations	the producer used to compute raw terrain elevations, themselves used to compute ElevationCurveData objects.
	displayLevel	the tile level to start display. Tiles whole level is less than displayLevel are not drawn by this Layer, and graphProducer is not asked to produce the corresponding graph tiles.
	quality	enable or not the quality mode (better display).
	deform	whether we apply a spherical deformation on the layer or not.

virtual proland::RoadElevationLayer::~RoadElevationLayer

(

)

[virtual]

Deletes this RoadOrthoLayer.

proland::RoadElevationLayer::RoadElevationLayer

(

)

[protected]

Creates an uninitialized RoadOrthoLayer.

Member Function Documentation

void proland::RoadElevationLayer::init	(	ptr< GraphProducer >	graphProducer,
		ptr< Program >	layerProgram,
		ptr< TileProducer >	elevations,
		int	displayLevel = 0,
		bool	quality = true,
		bool	deform = false
	)			[protected]

Initializes this RoadElevationLayer.

Parameters:

	graphProducer	the GraphProducer that produces the Graph tiles that this layer must draw.
	layerProgram	the Program to be used to draw the graphs in this layer.
	elevations	the producer used to compute raw terrain elevations, themselves used to compute ElevationCurveData objects.
	displayLevel	the tile level to start display. Tiles whole level is less than displayLevel are not drawn by this Layer, and graphProducer is not asked to produce the corresponding graph tiles.
	quality	enable or not the quality mode (better display).
	deform	whether we apply a spherical deformation on the layer or not.

virtual CurveData* proland::RoadElevationLayer::newCurveData	(	CurveId	id,
		CurvePtr	flattenCurve
	)			[virtual]

Returns a new CurveData, whose type depends on the class that implements CurveDataFactory.

Parameters:

	id	the CurveId of the described Curve.
	flattenCurve	flattened version of the described Curve.

Reimplemented from proland::CurveDataFactory.

Member Data Documentation

ptr< Mesh<vec4f, unsigned int> > proland::RoadElevationLayer::meshuv [private]

The mesh used for drawing road elevation profiles.

Contains vertex positions and UV attributes. The position is set to the vertex x,y coordinates. The u attribute contains the vertex z coordinate, and the v attribute the signed distance to the road axis (divided by the road width).
