Detailed Description

Define shapes and provide utilities for shapes stored as ISIS EquatorialCylindrical map.

This class will define shapes of ISIS target bodies with the shape defined by an EquatorialCylindrical map, as well as provide utilities to retrieve radii and photometric information for the intersection point.

Author: 2010-07-30 Debbie A. Cook

History

2012-12-19 Debbie A. Cook Added a check for an invalid radius in the intersectSurface() method, that was causing applications to hang. Also return a false if no ellipsoid itersection is found.

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

2015-10-01 Jeannie Backer - Made improvements to documentation and brought code closer to ISIS coding standards. Removed check for ellipsoid intersection in intersectSurface() method to prevent early return and attempt the iterative method even when the ellipsoid is not intersected. Fixes #1438

2018-01-05 Cole Neubauer - Fixed units conversion in intersectSurface so that the loop is stepping by radians per pixel, as recommended by Jeff Anderson (LROC team). Fixes #5245

◆ 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.

See also: hasValidTarget()

Returns: Three dimensional vector containing the ellipsoid radii values.
