Detailed Description

The PointIterator class is the base class for accessing the point data in a PointSource. Use PointSource::createIterator() to create a iterator.

See examples/src/UserTutorial.cpp for an example of using a PointIterator.

Member Function Documentation

virtual size_t PointIterator::getNextPoints

(

PointData &

points

)

[pure virtual]

This method gets the next group of points.

Parameters:

points

the destination buffer

Returns:

the number points written in the buffer

void PointIterator::init	(	const Bounds &	bounds,
		double	fraction,
		const PointInfo &	pointInfo,
		ProgressDelegate *	delegate
	)		[protected]

This method initializes iterator.

Parameters:

bounds	the region of interest (HUGE_VAL are handled)
fraction	the fraction of the points you want (use 1.0 for all the points and use 0.1 to keep every tenth point)
pointInfo	the list of channels to be extracted
delegate	a ProgressDelegate for feedback (can be NULL)

Note:

init() should have the same prototype a PointSource::createIterator()

bool PointIterator::useSample	(	double	x,
		double	y,
		double	z
	)		[inline, protected]
