Detailed Description

Polygon.

Polygon is an ordered set of points in space, sequential connection of these points produces polyline that approximates an object or part of an object.

◆ IsPlanar()

virtual bool MbPolygon3D::IsPlanar	(	MbPlacement3D &	plane,
		double	metricAccuracy = `Math::metricRegion`
	)		const

pure virtual

Check whether all points of polygon lie on the same plane with the given metricAccuracy accuracy. if so, then initialize 'plane' plane.

Implemented in MbFloatPolygon3D, and MbExactPolygon3D.
