Detailed Description

VolumeTile provides a framework for loosely coupling 3d image data with rendering algorithms. This allows TerrainTechnique's to be plugged in at runtime.

Constructor & Destructor Documentation

osgVolume::VolumeTile::VolumeTile

(

)

osgVolume::VolumeTile::VolumeTile	(	const VolumeTile &	,
		const osg::CopyOp &	copyop = osg::CopyOp::SHALLOW_COPY
	)

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

virtual osg::BoundingSphere osgVolume::VolumeTile::computeBound ( ) const

virtual

Compute the bounding sphere around Node's geometry or children. This method is automatically called by getBound() when the bounding sphere has been marked dirty via dirtyBound().

Reimplemented from osg::Group.

bool osgVolume::VolumeTile::getDirty ( ) const

inline

return true if the tile is dirty and needs to be updated,

Layer* osgVolume::VolumeTile::getLayer ( )

inline

const Layer* osgVolume::VolumeTile::getLayer ( ) const

inline

Locator* osgVolume::VolumeTile::getLocator ( )

inline

const Locator* osgVolume::VolumeTile::getLocator ( ) const

inline

const TileID& osgVolume::VolumeTile::getTileID ( ) const

inline

Get the TileID (layer, x,y,z) of the VolumeTile.

Volume* osgVolume::VolumeTile::getVolume ( )

inline

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

const Volume* osgVolume::VolumeTile::getVolume ( ) const

inline

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

VolumeTechnique* osgVolume::VolumeTile::getVolumeTechnique ( )

inline

Get the VolumeTechnique that will be used to render this tile.

const VolumeTechnique* osgVolume::VolumeTile::getVolumeTechnique ( ) const

inline

Get the const VolumeTechnique that will be used to render this tile.

void osgVolume::VolumeTile::init

(

)

Call init on any attached TerrainTechnique.

osgVolume::VolumeTile::META_Node	(	osgVolume	,
		VolumeTile
	)

void osgVolume::VolumeTile::setDirty

(

bool

dirty

)

Set the dirty flag on/off.

void osgVolume::VolumeTile::setLayer

(

Layer *

layer

)

void osgVolume::VolumeTile::setLocator ( Locator *  locator )

inline

void osgVolume::VolumeTile::setTileID

(

const TileID &

tileID

)

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

void osgVolume::VolumeTile::setVolume

(

Volume *

ts

)

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

void osgVolume::VolumeTile::setVolumeTechnique

(

VolumeTechnique *

VolumeTechnique

)

Set the VolumeTechnique that will be used to render this tile.

virtual void osgVolume::VolumeTile::traverse ( osg::NodeVisitor &  )

virtual

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

Reimplemented from osg::Group.
