◆ calculateDefaultNormal()

void Isis::ShapeModel::calculateDefaultNormal ( )

virtualinherited

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() is only suitable for a spheroid. This implementation is intended for irregular bodies so we expect triaxial ellipsoids.

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

Returns: The emission angle, in decimal degrees.

◆ setNormal() [2/2]

void Isis::ShapeModel::setNormal ( const std::vector< double > normal )

protectedinherited

Sets the surface normal for the currect intersection point.

Note: This method will throw an error if this ShapeModel doesn't have an intersection. Use the hasIntersection() method to verify before calling this method.

Parameters

normal Three dimensional surface normal vector.

◆ setSurfacePoint()

void Isis::ShapeModel::setSurfacePoint ( const SurfacePoint & surfacePoint )

virtualinherited

Set surface intersection point.

Parameters

surfacePoint Position coordinate for the surface point.

Reimplemented in Isis::BulletShapeModel.

◆ targetRadii()

std::vector< Distance > Isis::ShapeModel::targetRadii ( ) const

protectedinherited

Returns the radii of the body in km.

The radii are obtained from the target. Note: This method will throw an error if the ShapeModel does not have a valid target. Use the hasValidTarget() method to verify before calling this method.
