Detailed Description

Terrain provides a framework for loosely coupling height field data with height rendering algorithms.

This allows TerrainTechniques to be plugged in at runtime.

Member Function Documentation

virtual osgTerrain::Terrain* osgTerrain::Terrain::asTerrain ( )
inlinevirtual

Convert 'this' into a Transform pointer if Node is a Terrain, otherwise return 0.

Equivalent to dynamic_cast<Terrrain*>(this).

Reimplemented from osg::Node.

virtual const osgTerrain::Terrain* osgTerrain::Terrain::asTerrain ( ) const
inlinevirtual

convert 'const this' into a const Terrain pointer if Node is a Terrain, otherwise return 0.

Equivalent to dynamic_cast<const Terrain*>(this).

Reimplemented from osg::Node.

void osgTerrain::Terrain::dirtyRegisteredTiles ( int  dirtyMask = TerrainTile::ALL_DIRTY)
protected
TerrainTile::BlendingPolicy osgTerrain::Terrain::getBlendingPolicy ( ) const
inline

Get the default policy to use when deciding whether to enable/disable blending and use of transparent bin.

bool osgTerrain::Terrain::getEqualizeBoundaries ( ) const
inline

If true the boundaries between adjacent tiles will be equalized.

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.

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

Get the TerrainTile for a given TileID.

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

Get the const TerrainTile for a given TileID.

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

Get the vertical scale hint.

Terrain   
)
void osgTerrain::Terrain::registerTerrainTile ( TerrainTile tile)
protected
void osgTerrain::Terrain::setBlendingPolicy ( TerrainTile::BlendingPolicy  policy)

Set the default policy to use when deciding whether to enable/disable blending and use of transparent bin.

Note, the Terrain::BlendingPolicy value only sets the value for the TerrainTiles it encloses for the TerrainTile's that have their policy set to INHERIT. INHERIT is the default BlendingPolicy for both Terrain and TerrainTile, and if both are left to INERHIT then the policy used is ENABLE_BLENDING_WHEN_ALPHA_PRESENT.

void osgTerrain::Terrain::setEqualizeBoundaries ( bool  equalizeBoundaries)

If set to true the boundaries between adjacent tiles should be equalized.

Note, it is only possible to equalizae boundaries when the TerrainTile's contain properly assigned TileID's, databases built with VirtualPlanetBuilder-0.9.11 and older do not set the TileID, so databases must be built with later versions of VirtualPlanetBuilder to take advantage of boundary equalization.

void osgTerrain::Terrain::setSampleRatio ( float  ratio)

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)

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
void osgTerrain::Terrain::updateTerrainTileOnNextFrame ( TerrainTile terrainTile)

Tell the Terrain node to call the terrainTile's TerrainTechnique on the next update traversal.
