    • load

      public PointCloudData load​(java.io.InputStream data) throws java.lang.Exception
      Loads the data in the input stream and transforms it into Cartesian ecliptic coordinates. The reference system of the data goes as follows:
      • Origin of frame : Earth
      • X and Y axis in the EQUATORIAL PLANE with X pointing in the direction of vernal equinox.
      • Z perpendicular to the the EQUATORIAL PLANE in the north direction
      • The Y direction is defined to have (X,Y,Z) as a "three axis" positively oriented.
      The simulation reference system:
      • - XZ lies in the ECLIPTIC PLANE, with Z pointing to the vernal equinox.
      • - Y perpendicular to the ECLIPTIC PLANE pointing north.
      Parameters:
      data - The input stream with the data to load
      Throws:
      java.lang.Exception

    • parsef

      protected float parsef​(java.lang.String str)

    • parsed

      protected double parsed​(java.lang.String str)

    • parsei

      protected int parsei​(java.lang.String str)

    • correctSunLongitude

      protected Vector3d correctSunLongitude​(Vector3d pos, java.time.Instant t)
      Transforms the given vector to a heliotropic system using the given time.
      Parameters:
      pos - Position vector
      t - Time
      Returns:
      Vector3 with the position in the heliotropic reference frame

    • correctSunLongitude

      protected Vector3d correctSunLongitude​(Vector3d pos, java.time.Instant t, float origin)
      Transforms the given vector to a heliotropic system using the given time.
      Parameters:
      pos - Position vector
      t - Time
      origin - The origin angle
      Returns:
      Vector3 with the position in the heliotropic reference frame

    • writeDistVsTimeData

      public void writeDistVsTimeData​(java.lang.String filePath, PointCloudData data) throws java.lang.Exception
      Writes a file under the given path with the distance data
      Throws:
      java.lang.Exception
