  • Field Details

    • pos

      public Vector3b pos
      Position of this entity in the local reference system and internal units. This holds the position of the entity in the reference system of its parent. It is not the absolute position. If the entity has a ProperMotion component, the proper motion is applied for the current time. The position at epoch is kept in posEpoch. The absolute position is held at GraphNode.translation.

    • posEpoch

      public Vector3b posEpoch
      A copy of the original position, if any. If the entity has a ProperMotion component, this is the position at epoch ProperMotion.epochJd.

    • posSph

      public Vector2d posSph
      Position in the equatorial system; ra, dec.

    • size

      public float size
      Body size in internal units.

    • sizeInUnitsFlag

      public boolean sizeInUnitsFlag
      This flag indicates whether the size has already been set using the correct units. This is for backward compatibility with the data files.

    • sizeIsRadiusFlag

      public boolean sizeIsRadiusFlag
      This flag enables backwards-compatibility. When true, the body size is assumed to be a radius, and will be doubled in the initialization. Setting the size using any of the setRadius() methods sets this to false.

    • distToCamera

      public double distToCamera
      The distance to the camera from the focus center.

    • solidAngle

      public double solidAngle
      The view angle, in radians.

    • solidAngleApparent

      public double solidAngleApparent
      The view angle corrected with the field of view angle, in radians.

    • color

      public float[] color
      Base RGB color

    • labelColor

      public float[] labelColor

    • positionSetInScript

      public boolean positionSetInScript
      Flag to control whether the position of this object has been set in a script.
