Constructor & Destructor Documentation

FittedCurve()

volcart::segmentation::FittedCurve::FittedCurve	(	const std::vector< Voxel > &	vs,
		int	zIndex
	)

Construct curve from set of points and z-Index.

All points in generated curve are assumed to be at z = zIndex.

Parameters

vs	List of 2D points to fit
zIndex	Current location in curve
