fr.cnes.sirius.patrius.bodies.mesh.FieldData

public class FieldData
extends Object

Data container for FacetCelestialBody field data. Field data are data related to a FacetCelestialBody set of triangles at a given date. In particular given a list of visible triangles, it can provides a contour.

FieldData

public FieldData(AbsoluteDate date,
                 List<Triangle> visibleTriangles,
                 FacetCelestialBody body)
          throws PatriusException

Constructor.

Parameters:

date - date

visibleTriangles - visible triangle list

body - body

Throws:

PatriusException - thrown if computation failed (should not happen)

Method Detail

getDate

public AbsoluteDate getDate()

Returns the date.

Returns:

the date

getVisibleTriangles

public List<Triangle> getVisibleTriangles()

Returns the list of visible triangles. A triangle is visible if in the field of view, oriented toward the field and not masked by any other triangle.

Returns:

the list of visible triangles

getVisibleSurface

public double getVisibleSurface()

Returns the visible surface. This is the sum of all the visible triangles surface.

Returns:

the visible surface

getContour

public List<GeodeticPoint> getContour()

Returns the contour of the visible surface on the body. The contour is made of the vertices of the triangles which lies on the inner boundary of the visible surface (and are hence within the field of view).

Closest point to each other are next to each other in contour list.

Returns:

the contour of the visible surface on the body
