Constructor & Destructor Documentation

◆ pointToPointPlanarInterpolation() [1/3]

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
