Detailed Description

Convert between undistorted focal plane and ra/dec coordinates.

This base class is used to convert between undistorted focal plane coordinates (x/y) in millimeters and sky (ra/dec). This class handles the case of framing cameras.

bool Isis::CameraSkyMap::SetFocalPlane ( const double  ux,
const double  uy,
const double  uz 
)
virtual

Compute ra/dec from focal plane coordinate.

This method will compute the right ascension and declination given an undistorted focal plane coordinate. Note that the ra/dec values can be obtained from the parent camera class passed into the constructor.

Parameters
uxdistorted focal plane x in millimeters
uydistorted focal plane y in millimeters
uzdistorted focal plane z in millimeters
Returns
conversion was successful

Reimplemented in Isis::VimsSkyMap, and Isis::RadarSkyMap.

bool Isis::CameraSkyMap::SetSky ( const double  ra,
const double  dec 
)
virtual

Compute undistorted focal plane coordinate from ra/dec.

Parameters
raThe right ascension angle
decThe declination
Returns
conversion was successful
Todo:

what happens if we are looking behind the focal plane?????

what happens if we are looking parallel to the focal plane??

can lookC[2] == zero imply parallel

can this all be solved by restricting the physical size of the focal plane?

Reimplemented in Isis::VimsSkyMap, Isis::LineScanCameraSkyMap, and Isis::RadarSkyMap.
