fr.cnes.sirius.patrius.bodies.mesh.SurfacePointedData

public class SurfacePointedData
extends Object

Data container for FacetBodyShape surface data. A surface data is a FacetBodyShape surface data derived from a date and a body point (incidence, solar incidence, distance, etc.). The light propagation is considered as instantaneous to compute the solar incidence.
