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::TerrainTile::TerrainTile

(

)

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

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osgTerrain::TerrainTile::~TerrainTile

(

)

[protected, virtual]

Member Function Documentation

osgTerrain::TerrainTile::META_Node	(	osgTerrain	,
		TerrainTile
	)

virtual void osgTerrain::TerrainTile::traverse

(

osg::NodeVisitor &

)

[virtual]

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

Reimplemented from osg::Group.

void osgTerrain::TerrainTile::init

(

)

Call init on any attached TerrainTechnique.

void osgTerrain::TerrainTile::setTerrain

(

Terrain *

ts

)

Set the Terrain that this Terrain tile is a member of.

Terrain* osgTerrain::TerrainTile::getTerrain

(

)

[inline]

Get the Terrain that this Terrain tile is a member of.

const Terrain* osgTerrain::TerrainTile::getTerrain

(

)

const [inline]

Get the const Terrain that this Terrain tile is a member of.

void osgTerrain::TerrainTile::setTileID

(

const TileID &

tileID

)

Set the TileID (layer, x,y) of the TerrainTile. The TileID is used so it can be located by its neighbours via the enclosing Terrain node that manages a map of TileID to TerraiTiles.

const TileID& osgTerrain::TerrainTile::getTileID

(

)

const [inline]

Get the TileID (layer, x,y) of the TerrainTile.

void osgTerrain::TerrainTile::setTerrainTechnique

(

TerrainTechnique *

TerrainTechnique

)

Set the TerrainTechnique

TerrainTechnique* osgTerrain::TerrainTile::getTerrainTechnique

(

)

[inline]

Get the TerrainTechnique

const TerrainTechnique* osgTerrain::TerrainTile::getTerrainTechnique

(

)

const [inline]

Get the const TerrainTechnique

void osgTerrain::TerrainTile::setLocator

(

Locator *

locator

)

[inline]

Set the coordinate frame locator of the terrain node. The locator takes non-dimensional s,t coordinates into the X,Y,Z world coords and back.

Locator* osgTerrain::TerrainTile::getLocator

(

)

[inline]

Get the coordinate frame locator of the terrain node.

const Locator* osgTerrain::TerrainTile::getLocator

(

)

const [inline]

Get the coordinate frame locator of the terrain node.

void osgTerrain::TerrainTile::setElevationLayer

(

Layer *

layer

)

Set the layer to use to define the elevations of the terrain.

Layer* osgTerrain::TerrainTile::getElevationLayer

(

)

[inline]

Get the layer to use to define the elevations of the terrain.

const Layer* osgTerrain::TerrainTile::getElevationLayer

(

)

const [inline]

Get the const layer to use to define the elevations of the terrain.

void osgTerrain::TerrainTile::setColorLayer	(	unsigned int	i,
		Layer *	layer
	)

Set a color layer with specified layer number.

Layer* osgTerrain::TerrainTile::getColorLayer

(

unsigned int

i

)

[inline]

Get color layer with specified layer number.

const Layer* osgTerrain::TerrainTile::getColorLayer

(

unsigned int

i

)

const [inline]

Set const color layer with specified layer number.

unsigned int osgTerrain::TerrainTile::getNumColorLayers

(

)

const [inline]

Get the number of colour layers.

void osgTerrain::TerrainTile::setRequiresNormals

(

bool

flag

)

[inline]

Set hint to whether the TerrainTechnique should create per vertex normals for lighting purposes.

bool osgTerrain::TerrainTile::getRequiresNormals

(

)

const [inline]

Get whether the TerrainTechnique should create per vertex normals for lighting purposes.

void osgTerrain::TerrainTile::setTreatBoundariesToValidDataAsDefaultValue

(

bool

flag

)

[inline]

Set the hint to whether the TerrainTechnique should treat the invalid Layer entries that at are neigbours to valid entries with the default value.

bool osgTerrain::TerrainTile::getTreatBoundariesToValidDataAsDefaultValue

(

)

const [inline]

Get whether the TeatBoundariesToValidDataAsDefaultValue hint.

virtual osg::BoundingSphere osgTerrain::TerrainTile::computeBound

(

)

const [virtual]

Compute the bounding volume of the terrain by computing the union of the bounding volumes of all layers.

Reimplemented from osg::Group.
