Constructor & Destructor Documentation

◆ NaifDskShape() [1/3]

Isis::NaifDskShape::NaifDskShape ( )

Generic constructor sets type to a TIN.

References Isis::ShapeModel::setName().

◆ NaifDskShape() [2/3]

Isis::NaifDskShape::NaifDskShape	(	Target *	target,
		Pvl &	pvl
	)

Constructor provided for instantiation from an ISIS cube.

This constructor is typically used for and ISIS cube that has been initialized by spiceinit. The DEM name should be that of a NAIF DSK file. This constructor will throw an exception if it fails to open the DSK file.

Author: 2014-02-12 Kris Becker

Parameters

target	Target object describing the observed body
pvl	ISIS Cube label. Extract the name of the DEM from the Kernels group

References Isis::PvlObject::findGroup(), Isis::PvlContainer::hasKeyword(), Isis::ShapeModel::setName(), and Isis::PvlObject::Traverse.

◆ NaifDskShape() [3/3]

Isis::NaifDskShape::NaifDskShape ( const NaifDskPlateModel & model )

Constructor for creating new shape model from the same DSK file.

This constructor provides the ability to create a formal shape model from the NAIF DSK plate model file already opened. This approach allows multiple threads to access the same DSK file interface without the overhead of opening many instances of the same file.

Author: 2014-02-12 Kris Becker

Parameters

model DSK plate model from an existing NaidDskPlateModel (see the model() method

◆ ~NaifDskShape()

Isis::NaifDskShape::~NaifDskShape ( )

Destructor - cleanup is handled automagically.

Member Function Documentation

◆ calculateDefaultNormal()

void Isis::NaifDskShape::calculateDefaultNormal ( )

virtual

Return the surface normal of the ellipsoid as the default.

Implements Isis::ShapeModel.

References calculateSurfaceNormal().

◆ calculateEllipsoidalSurfaceNormal()

void Isis::ShapeModel::calculateEllipsoidalSurfaceNormal ( )

protectedinherited

Calculates the ellipsoidal surface normal.

References _FILEINFO_.

◆ calculateLocalNormal()

void Isis::NaifDskShape::calculateLocalNormal ( QVector< double *> neighborPoints )

virtual

Compute the normal for a local region of surface points.

This method will calculate the surface normal of an assumed very local region of points. This method is provided to fullfil the specs of the ShapeModel class but this approach is not the most efficent means to accomplish this for a pre-exising intercept point. See setLocalNormalFromIntercept() for this.

The ShapeModel class makes the assumption that the four pixel corners of the center intercept point forms a plane from which a surface normal can be computed. For the Naif DSK plate model, we have already identified the plate (see m_intercept) from the DSK plate model (m_model) of the intercept point that provides it directly. That is what setLocalNormalFromIntercept() provides.

So, this implementation will compute the centroid of the neighboring points and make a determination if it intercepts the current intercept plate as defined by m_intercept - if it is valid. If it does not exist or does not intercept the plate, a new intercept point is computed and returned here.

◆ ellipsoidNormal()

QVector< double > Isis::NaifDskShape::ellipsoidNormal ( )

Compute the true surface normal vector of an ellipsoid.

This routine is used instead of the one provided by the ShapeModel implementation. This is primarly because ShapeModel::calculateEllipsoidalSurfaceNormal() it is only suitable for a spheroid. This implementation is intended for irregular bodies so we expect triaxial ellipsoids.

Author: 2014-02-12 Kris Becker

Returns: QVector<double> Normal vector at the intercept point relative to the ellipsoid (not the plate model)

◆ emissionAngle()

double Isis::ShapeModel::emissionAngle ( const std::vector< double > & observerBodyFixedPosition )

virtualinherited

Computes and returns emission angle, in degrees, given the observer position.

Emission Angle: The angle between the surface normal vector at the intersection point and the vector from the intersection point to the observer (usually the spacecraft). The emission angle varies from 0 degrees when the observer is viewing the sub-spacecraft point (nadir viewing) to 90 degrees when the intercept is tangent to the surface of the target body. Thus, higher values of emission angle indicate more oblique viewing of the target.

Parameters
