Constructor & Destructor Documentation

proland::OrthoProducer::OrthoProducer	(	ptr< TileCache >	cache,
		ptr< TileProducer >	residualTiles,
		ptr< Texture2D >	orthoTexture,
		ptr< Texture2D >	residualTexture,
		ptr< Program >	upsample,
		vec4f	rootNoiseColor,
		vec4f	noiseColor,
		vector< float > &	noiseAmp,
		bool	noiseHsv,
		float	scale,
		int	maxLevel
	)

Creates a new OrthoProducer.

Parameters:

	cache	the cache to store the produced tiles. The underlying storage must be a GPUTileStorage.
	residualTiles	the producer producing the residual tiles. This producer should produce its tiles in a CPUTileStorage of unsigned ybte type. The size of the residual tiles (without borders) must be equal to the size of the produced tiles (without borders). The border sizes must be the same.
	orthoTexture	a texture used to produce the tiles. Its size must be equal to the produced tile size (including borders).
	residualTexture	a texture used to produce the tiles. Its size must be equal to the produced tile size (including borders).
	upsample	the Program to perform the upsampling and add procedure on GPU. See Ortho producer.
	scale	scaling factor used for residual values.
	maxLevel	maximum quadtree level, or -1 to allow any level.

virtual proland::OrthoProducer::~OrthoProducer

		Resource *	r,
		const string &	name,
		ptr< ResourceDescriptor >	desc,
		const TiXmlElement *	e = NULL
	)			[protected]

Initializes this OrthoProducer from a Resource.

Parameters:

	manager	the manager that will manage the created resource.
	r	the resource.
	name	the resource name.
	desc	the resource descriptor.
	e	an optional XML element providing contextual information (such as the XML element in which the resource descriptor was found).
