Constructor & Destructor Documentation

proland::CPUElevationProducer::CPUElevationProducer	(	ptr< TileCache >	cache,
		ptr< TileProducer >	residualTiles
	)

Creates a new CPUElevationProducer.

Parameters:

	cache	the cache to store the produced tiles. The underlying storage must be a CPUTileStorage of float type.
	residualTiles	the producer producing the residual tiles. This producer should produce its tiles in a CPUTileStorage of float type. The size of the residual tiles (without borders) must be a multiple of the size of the elevation tiles (without borders).

virtual proland::CPUElevationProducer::~CPUElevationProducer

(

)

[virtual]

Deletes this CPUElevationProducer.

proland::CPUElevationProducer::CPUElevationProducer

(

)

[protected]

Creates an uninitialized CPUElevationProducer.

Member Function Documentation

static float proland::CPUElevationProducer::getHeight	(	ptr< TileProducer >	producer,
		int	level,
		float	x,
		float	y
	)			[static]

Returns the terrain altitude at a given point, at a given level.

The corresponding tile must be in cache before calling this method.

Parameters:

	producer	a CPUElevationProducer or an equivalent (i.e. a % producer using an underlying CPUTileStorage of float type).
	level	level at which we want to get the altitude.
	x	physical x coordinate of the point to get (in meters from the terrain center).
	y	physical y coordinate of the point to get (in meters from the terrain center).

void proland::CPUElevationProducer::init	(	ptr< TileCache >	cache,
		ptr< TileProducer >	residualTiles
	)			[protected]

Initializes this CPUElevationProducer.

Parameters:

	cache	the cache to store the produced tiles. The underlying storage must be a CPUTileStorage of float type.
	residualTiles	the producer producing the residual tiles. This producer should produce its tiles in a CPUTileStorage of float type. The size of the residual tiles (without borders) must be a multiple of the size of the elevation tiles (without borders).

Member Data Documentation

ptr<TileProducer> proland::CPUElevationProducer::residualTiles [private]

The producer producing the residual tiles.

This producer should produce its tiles in a CPUTileStorage of float type. The size of the residual tiles (without borders) must be a multiple of the size of the elevation tiles (without borders).
