Detailed Description

Base class for arguments passed into DtSignaturePropagator::calculateApparentSignature.

This class simply encapsulates arguments for passing into the DtSignaturePropagator::calculateApparentSignature method. Some propagators may use derived version of this class that have more arguments.

virtual void DtSignaturePropagatorArgs::setViewpointLocalLocation ( const DtVector &  loc )

virtual

The local location of the viewer of the signature.

virtual DtVector DtSignaturePropagatorArgs::viewpointLocalLocation ( ) const

virtual

The local location of the viewer of the signature.

virtual void DtSignaturePropagatorArgs::setTargetObject ( const DtVrfObject *  obj )

virtual

The object that is the originator of the signature.

virtual const DtVrfObject* DtSignaturePropagatorArgs::targetObject ( ) const

virtual

Returns the target object.

virtual void DtSignaturePropagatorArgs::setViewingObject ( const DtVrfObject *  obj )

virtual

The object that is the viewer of the signature.

virtual const DtVrfObject* DtSignaturePropagatorArgs::viewingObject ( ) const

virtual

Returns the viewing object.

virtual void DtSignaturePropagatorArgs::setMinSignatureThreshold ( double  sig )

virtual

The smallest signature value that is relevant for propagating the signature.

Any results that fall below this value may be returned as 0. This parameter is for optimization, and is not mandatory. The default is 0, which will always return the correct value.

virtual double DtSignaturePropagatorArgs::minSignatureThreshold ( ) const

virtual

The smallest signature value that is relevant for propagating the signature.

Any results that fall below this value may be returned as 0. This parameter is for optimization, and is not mandatory. The default is 0, which will always return the correct value.

Member Data Documentation

DtVector DtSignaturePropagatorArgs::myViewpointLocalLocation

protected

The local location of the viewer of the signature i.e. the location we are trying to detect from.

const DtVrfObject* DtSignaturePropagatorArgs::myTargetObject

protected

The object that is the originator of the signature, the object to be detected.

const DtVrfObject* DtSignaturePropagatorArgs::myViewingObject

protected

The object that is the viewer of the signature, the object the sensor is on.

double DtSignaturePropagatorArgs::myMinimumSignatureThreshold

protected

The smallest signature value that is relevant for propagating the signature.

Any results that fall below this value may be returned as 0. This parameter is for optimization, and is not mandatory. The default is 0, which will always return the correct value.

bool DtSignaturePropagatorArgs::myLosValueIfDataUnavaialble

protected

This parameter is only used in the case of paging or streaming terrains where the sensor calculation is done over an area where data is not yet available.

This parameter holds the LOS value that will be used if the LOS check against the terrain results in a "data unavailable" state. If true, the LOS will be treated as if it is clear. If false, no data will be treated as if the LOS is blocked. Default value is false.
