Detailed Description

Height Field Base Class. A height field is specified by a two-dimensional array of rows x columns points [c,r] together with a height function 'height' which returns the height for each height field element.

Implemented in VRS::ImageHeightField.

virtual Vector VRS::HeightField::vertex	(	int	c,
		int	r
	)			const [virtual]

virtual Vector VRS::HeightField::normal	(	int	c,
		int	r
	)			const [virtual]

r and c must be in the range [0,c-1]x[0,r-1].

virtual Iterator<Vector>* VRS::HeightField::newIterator

(

)

const [virtual]

virtual Iterator<Vector>* VRS::HeightField::newNormalIterator

(

)

const [virtual]

Creates an instance of an iterator for the vertex data and normal data. The data is traversed row by row. To render a heightfield, create a mesh and pass these iterators to it.

virtual Bounds VRS::HeightField::boundingBox

(

)

const [virtual]

VRS::HeightField::VRS_TYPEINFO	(	HeightField	,
		SharedObj
