void Isis::DemShape::calculateDefaultNormal ( )
virtualinherited

This method calculates the default normal (Ellipsoid for backwards compatability) for the DemShape.

Implements Isis::ShapeModel.

Parameters

void Isis::DemShape::calculateSurfaceNormal ( )

double Isis::ShapeModel::emissionAngle ( const std::vector< double > &  sB)
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 a vector from the intersection point to the spacecraft. The emission angle varies from 0 degrees when the spacecraft 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
sB,:Spacecraft position in body-fixed coordinates
Returns
Emmision angle in decimal degrees
