Member Function Documentation

virtual bool zxhGradientBase::ComputeMetricGradient	(	zxhMetricBase *	pMetric,
		zxhTransformBase *	pInfluence = 0
	)		[pure virtual]

methods for gradient type objects computer gradient, influence control status for optimisation if infl==0, then use m_fDifferentialStep if pDifferentialStep==0,then using m_fDifferentialStep

Implemented in zxhGradientMultiRigid, zxhTransformAffine, zxhTransformFFD, zxhTransformFieldGradient, zxhTransformLocalAffines, and zxhTransformMultipleAffines.

virtual bool zxhGradientBase::PrePostComputeMetricGradient	(	zxhMetricBase *	pMetric,
		zxhTransformBase *	pInfluence,
		bool	isPre
	)		[inline, virtual]

return false means did nothing

adjust influence and differential virtual bool ComputeAdjustment( zxhTransformFFDBase * pInfl ) {return false; } ;

Reimplemented in zxhGradientFFDBase, and zxhTransformFFD.
