Matrix osg::HeightField::computeRotationMatrix ( ) const

inline

unsigned int osg::HeightField::getBorderWidth ( ) const

inline

Get the width in number of cells in from the edge that the height field should be rendered from.

osg::FloatArray* osg::HeightField::getFloatArray ( )

inline

Get the FloatArray height data.

const osg::FloatArray* osg::HeightField::getFloatArray ( ) const

inline

Get the const FloatArray height data.

float osg::HeightField::getYInterval ( ) const

inline

osg::HeightField::META_Shape	(	osg	,
		HeightField
	)

void osg::HeightField::setBorderWidth ( unsigned int  borderWidth )

inline

Set the width in number of cells in from the edge that the height field should be rendered from. This exists to allow gradient and curvature continutity to be maintained between adjacent HeightField, where the border cells will overlap adjacent HeightField.

void osg::HeightField::setHeight ( unsigned int  c, unsigned int  r, float  value  )

inline

void osg::HeightField::setOrigin ( const osg::Vec3 &  origin )

inline

void osg::HeightField::setRotation ( const Quat &  quat )

inline

void osg::HeightField::setSkirtHeight ( float  skirtHeight )

inline

Set the height of the skirt to render around the edge of HeightField. The skirt is used as a means of disguising edge boundaries between adjacent HeightField, particularly of ones with different resolutions.
