Class AttractionData

java.lang.Object

fr.cnes.sirius.patrius.forces.gravity.grid.AttractionData

All Implemented Interfaces:

Serializable

public class AttractionData
extends Object
implements Serializable

Attraction data: 3D acceleration and potential for all grid points. Grid point can be expressed in any coordinates system defined by interface GridSystem (currently either in 3D coordinates or spherical coordinates).

This class is to be used in conjunction with GridGravityModel for attraction force defined by a grid.
