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.

virtual osgVolume::VolumeTile::~VolumeTile ( ) [protected, virtual]

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]

const Locator* osgVolume::VolumeTile::getLocator ( ) const [inline]

Locator* osgVolume::VolumeTile::getLocator ( ) [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.

const VolumeTechnique* osgVolume::VolumeTile::getVolumeTechnique ( ) const [inline]

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

VolumeTechnique* osgVolume::VolumeTile::getVolumeTechnique ( ) [inline]

Get the 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.
