Detailed Description

Class representing a circular order of a set of points around their barycenter.

It is used with the STL sort() algorithm to sort the point of the two polygons

Member Enumeration Documentation

enum INTERP_KERNEL::ProjectedCentralCircularSortOrder::CoordType

Enumeration of different planes to project on when calculating order.

Enumerator:

XY
XZ
YZ

Constructor & Destructor Documentation

INTERP_KERNEL.ProjectedCentralCircularSortOrder.ProjectedCentralCircularSortOrder	(	const double *	barycenter,
		const CoordType	type
	)

Constructor.

Parameters:

	barycenter	double[3] containing the barycenter of the points to be compared
	type	plane to project on when comparing. The comparison will not work if all the points are in a plane perpendicular to the plane being projected on

Member Function Documentation

bool INTERP_KERNEL.ProjectedCentralCircularSortOrder.operator()	(	const double *	pt1,
		const double *	pt2
	)

Comparison operator.

Compares the relative position between two points in their ordering around the barycenter.

Parameters:

	pt1	a double[3] representing a point
	pt2	a double[3] representing a point

Returns:

true if the angle of the difference vector between pt1 and the barycenter is greater than that of the difference vector between pt2 and the barycenter.
