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

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.
