Detailed Description

Dip filtering Attribute.

DipFilter convolves a signal with the on the command-line specified signal.

minvel/maxvel is the cutoff velocity (m/s) or dip (degrees), depending on the z-range unit.

Azimuth is given in degrees from the inline, in the direction of increasing crossline-numbers.

Taper is given as percentage. Tapering is done differently for the three different filtertype. Bandpass tapers at the upper and lower taperlen/2 parts of t the interval. Lowpass tapers from the maxvel down to 100-taperlen of the maxvel. Highpass tapers from minvel to 100+taperlen of minvel

The azimuthrange is tapered in the same way as bandpass.

Member Function Documentation

bool Attrib::DipFilter::allowParallelComputation ( ) const

inlineprotectedvirtual

Reimplemented from Attrib::Provider.

bool Attrib::DipFilter::computeData	(	const DataHolder &	output,
		const BinID &	relpos,
		int	t0,
		int	nrsamples,
		int	threadidx
	)		const

protectedvirtual

The system will use the algorithm specified in this function to compute the attribute's outputs. The results will be stored as different series in the DataHolder output.

Parameters

threadid thread identifier that may be handy when using multiple threads.

Implements Attrib::Provider.

static Provider* Attrib::DipFilter::createInstance ( Desc & )

staticprotected

const BinID* Attrib::DipFilter::desStepout	(	int	input,
		int	output
	)		const

protectedvirtual

The system will try to supply the attribute with the desired stepout, but will not take the desired stepout into account when computing the volume that can be computed.

Returns: the desired stepout on input if output is going to be computed, or NULL if no stepout is desired.

Reimplemented from Attrib::Provider.

const Interval<int>* Attrib::DipFilter::desZSampMargin	(	int	input,
		int	output
	)		const

protectedvirtual

The gate is specified in the trace samples, and is in addition to the gate specified in desZMargin. The system will try to supply the attribute with the desired gate, but will not take the desired gate into account when computing the volume that can be computed.

Returns: the extra gate desired on input if output is going to be computed, or NULL if no extra gate is desired.
