Constructor & Destructor Documentation

DtTerrainAltitudeTable::DtTerrainAltitudeTable	(	const osgEarth::Map *	map,
		unsigned	lod,
		double	bias = 30000,
		double	factor = 2
	)

Create from map.

DtTerrainAltitudeTable::DtTerrainAltitudeTable ( const osgEarth::TileKey &  tilekey, const osgEarth::Map *  map, unsigned  lod, MAKVRinTerra::DtProj::CPtr  , double  bias, double  factor  )

protected

Create from map and specific tilekey.

DtTerrainAltitudeTable::DtTerrainAltitudeTable ( const osgEarth::TileKey &  tilekey, const osg::HeightField *  field, unsigned  xmin, unsigned  xmax, unsigned  ymin, unsigned  ymax, MAKVRinTerra::DtProj::CPtr  , double  bias, double  factor  )

protected

Create from a section of a heightfield.

Member Function Documentation

void DtTerrainAltitudeTable::breakUpChord	(	const MAKVRinTerra::DtProj &	proj,
		DtChord	,
		ChordVector &	chords
	)

void DtTerrainAltitudeTable::removeSegments ( const DtChord &  chord, SegmentSet &  set  )

protected

Creates a set of segments of a chord for which the chord is higher in altitude than the max height for that segment. The segments are returned as pairs of parameter values, where the parameter (t-value) moves from 0 at the start of the chord to 1 at the end of the chord.

void DtTerrainAltitudeTable::createBoundaries ( )

protected

setup boundary info once tilekey has been set

void DtTerrainAltitudeTable::setMaxHeight ( )

protected

update max height from max heights of children
