Detailed Description

Terrain provides a framework for loosely coupling height field data with height rendering algorithms. This allows TerrainTechnique's to be plugged in at runtime.

Constructor & Destructor Documentation

osgTerrain::Terrain::Terrain ( )

osgTerrain::Terrain::Terrain	(	const Terrain &	,
		const osg::CopyOp &	copyop = `osg::CopyOp::SHALLOW_COPY`
	)

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osgTerrain::Terrain::~Terrain ( ) [protected, virtual]

Member Function Documentation

void osgTerrain::Terrain::dirtyRegisteredTiles ( ) [protected]

float osgTerrain::Terrain::getSampleRatio ( ) const [inline]

Get the sample ratio hint.

TerrainTechnique* osgTerrain::Terrain::getTerrainTechniquePrototype ( ) [inline]

Get the TerrainTechnique prototype

const TerrainTechnique* osgTerrain::Terrain::getTerrainTechniquePrototype ( ) const [inline]

Get the const TerrainTechnique protype

const TerrainTile* osgTerrain::Terrain::getTile ( const TileID & tileID ) const

Get the const TerrainTile for a given TileID.

TerrainTile* osgTerrain::Terrain::getTile ( const TileID & tileID )

Get the TerrainTile for a given TileID.

float osgTerrain::Terrain::getVerticalScale ( ) const [inline]

Get the vertical scale hint.

osgTerrain::Terrain::META_Node	(	osgTerrain	,
		Terrain
	)

void osgTerrain::Terrain::registerTerrainTile ( TerrainTile * tile ) [protected]

void osgTerrain::Terrain::setSampleRatio ( float ratio ) [inline]

Set the sample ratio hint that TerrainTile should use when building geometry. Defaults to 1.0, which means use all original sample points.

void osgTerrain::Terrain::setTerrainTechniquePrototype ( TerrainTechnique * technique ) [inline]

Set the TerrainTechnique prototype from which TerrainTiles can clone the techniques from.

void osgTerrain::Terrain::setVerticalScale ( float scale ) [inline]

Set the vertical scale hint.

virtual void osgTerrain::Terrain::traverse ( osg::NodeVisitor & ) [virtual]

Traverse downwards : calls children's accept method with NodeVisitor.

Reimplemented from osg::Group.

void osgTerrain::Terrain::unregisterTerrainTile ( TerrainTile * tile ) [protected]
