double ApproxMVBB::DiameterEstimator::estimateDiameter	(	Diameter::TypeSegment *	theDiam,
		double const **	theList,
		const int	first,
		const int	last,
		const int	dim,
		double	epsilon
	)

Raw function to estimate the diameter of a point cloud

Parameters:

theDiam	returns the diameter info
theList	input point cloud (look at example how to call this function)
first	First index into the point cloud
dim	dimension of the points
epsilon	the accuracy of the diameter estimation such that [diam_min, diam_max] <= epsilon, and [diam_min, diam_max] contains the true diameter
