Method Detail

getIntersectionPoints

Vector3D[] getIntersectionPoints(Line line,
                                 Frame frame,
                                 AbsoluteDate date)
                          throws PatriusException

Compute the intersection points with a line.

Parameters:

line - the line

frame - in which line is expressed

date - date of the line in given frame

Returns:

the intersection points if they exist. If no intersection is found, the dimension is zero

Throws:

PatriusException - if line cannot be converted to body frame

distanceTo

double distanceTo(Line line,
                  Frame frame,
                  AbsoluteDate date)
           throws PatriusException

Computes the distance to a line.

Parameters:

line - the line

frame - in which line is expressed

date - date of the line in given frame

Returns:

the shortest distance between the the line and the shape

Throws:

PatriusException - if line cannot be converted to body frame

getName

String getName()

Returns:

the name of the shape

getLocalRadius

double getLocalRadius(Vector3D position,
                      Frame frame,
                      AbsoluteDate date,
                      PVCoordinatesProvider occultedBody)
               throws PatriusException

Calculate the apparent radius.

Parameters:

position - spacecraft position

frame - frame in which position is expressed

date - date of position

occultedBody - body occulted by this

Returns:

apparent radius

Throws:

PatriusException - if PVCoordinatesProvider computation fails
