Member Function Documentation

◆ transform()

virtual void OpenZGY::Impl::ZgyMetaAndTools::transform	(	const corners_t &	from,
		const corners_t &	to,
		std::vector< std::array< float64_t, 2 >> &
	)		const

overridevirtual

General coordinate conversion of an array of points. (NOT IMPLEMENTED YET)

Parameters

from	control points in the current coordinate system.
to	control points in the desired coordinate system.

Convert coordinates in place, with the conversion defined by giving the values of 3 arbitrary control points in both the "from" and "to" coordinate system. A common choice of arbitrary points is to use three of the lattice corners. As a convenience the "from" and "to" parameters are declared as corners_t so the caller can pass corners(), annotcorners(), or indexcorners() directly.

Implements OpenZGY::IZgyTools.

◆ transform1()

virtual std::array<float64_t,2> OpenZGY::Impl::ZgyMetaAndTools::transform1	(	const corners_t &	from,
		const corners_t &	to,
		const std::array< float64_t, 2 > &
	)		const

overridevirtual

General coordinate conversion of a single coordinate pair.
