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  ) 

TerrainTechnique* osgTerrain::TerrainTile::getTerrainTechnique (  )  [inline]

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.
