Detailed Description

Hor+Vert sampling in 3D surveys.

When slices are to be taken from a TrcKeyZSampling, they should be ordered as follows:

Dir	Dim1	Dim2
Inl	Crl	Z
Crl	Inl	Z
Z	Inl	Crl

See also the direction() and dimension() free functions.

adjustTo()

bool TrcKeyZSampling::adjustTo	(	const TrcKeyZSampling &	availabletkzs,
		bool	falsereturnsdummy = false
	)

adjusts the non-flat dimensions of the desired "this" tkzs to the availabletkzs for optimal texture data display.

inline

defaultDir()

Dir TrcKeyZSampling::defaultDir

(

)

const

'flattest' direction, i.e. direction with smallest size. If equal, prefer Inl then Crl then Z
