Constructor & Destructor Documentation

◆ pointToPointPlanarInterpolation() [1/4]

pointToPointPlanarInterpolation ( const pointToPointPlanarInterpolation & )

default

Copy construct.

◆ pointToPointPlanarInterpolation() [2/4]

pointToPointPlanarInterpolation	(	const pointField &	sourcePoints,
		const pointField &	destPoints,
		const scalar	perturb,
		const bool	nearestOnly = `false`
	)

Construct from 3D locations.

Determines local coordinate system from sourcePoints and maps onto that. If nearestOnly skips any local coordinate system and triangulation and uses nearest vertex only

◆ pointToPointPlanarInterpolation() [3/4]

pointToPointPlanarInterpolation	(	const coordinateSystem &	referenceCS,
		const pointField &	sourcePoints,
		const pointField &	destPoints,
		const scalar	perturb
	)

Construct from coordinate system and locations.
