History

2012-12-21 Debbie A. Cook - Cleaned up intersectSurface method to reflect changes made to ShapeModel class. References #1343.

2015-04-30 Jeannie Backer - Added isDEM() method. References #2243.

2015-07-21 Kristin Berry - Added NaifStatus::CheckErrors() to see if any NAIF errors were signaled. References #2248.

2016-06-13 Kelvin Rodriguez - Removed redundant contructor EllipsoidShape(Target, Pvl). References #2214

2017-05-19 Tyler Wilson - calculateSurfaceNormal() and calculateDefaultNormal() now call calculateLocalNormal(), which calculates the normal vector to an ellipsoid. Prior to this, they were calling ShapeModel::calculateEllipsoidalSurfaceNormal() function which was incorrectly returning the normal vector to a sphere and not an ellipsoid. Fixes #1028.

2017-06-07 Kristin Berry - Added a using declaration so that the new intersectSurface methods in ShapeModel are accessible by EllipsoidShape.

◆ calculateLocalNormal()

void Isis::EllipsoidShape::calculateLocalNormal ( QVector< double * > cornerNeighborPoints )

virtual

Calculate the local surface normal of the current intersection point.

Calculates the unit normal to an ellipsoid at the point of intersection.

In the event that the three axial radii of the body are equal, this method returns the normal vector for a sphere.

The implicit equation for an ellipsoid is: U(x,y,z) = x^2/a^2 + y^2/b^2 + z^2/c^2 -1 =0

The normal to U(x,y,z) is given by:

n = grad(U)/norm(U)

i.e. as:

n = <ux,uy,uz>/sqrt(ux^2,+uy^2+uz^2)

Parameters

cornerNeighborPoints

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

observerBodyFixedPosition Three dimensional position of the observer, in the coordinate system of the target body.

Returns: The emission angle, in decimal degrees.

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.

See also: hasValidTarget()

Returns: Three dimensional vector containing the ellipsoid radii values.
