    Modifier and Type
    Method
    Description
    Vector3D
    getDirection()
    Returns a vector pointing from the midpoint of this component towards the readout end of the component (e.g. towards the PMT of a scintillator).
    double
    getLength()
    Returns the length of this component.
    Line3D
    getLine()
    Returns a line running down the middle of the length of the component such that the two end points of the line segment are at the geometric centers of the two polygons defining this component's volume.
    boolean
    getVolumeIntersection(Line3D line, Point3D inIntersect, Point3D outIntersect)
    Returns true if the given line segment intersect the volume-shape twice (one incoming intersection and one out going) and stores the incoming and outgoing intersection points are stored in the first and second Point3D objects given as arguments respectively.
    protected void
    onRotateX(double angle)
    Classes extending AbstractComponent should implement onRotateX so that any additional geometric data they contain is rotated appropriately when AbstractComponent's rotateX method is invoke.
    protected void
    onRotateY(double angle)
    Classes extending AbstractComponent should implement onRotateY so that any additional geometric data they contain is rotated appropriately when AbstractComponent's rotateY method is invoke.
    protected void
    onRotateZ(double angle)
    Classes extending AbstractComponent should implement onRotateZ so that any additional geometric data they contain is rotated appropriately when AbstractComponent's rotateZ method is invoke.
    protected void
    onTranslateXYZ(double dx, double dy, double dz)
    Classes extending AbstractComponent should implement onTranslateXYZ so that any additional geometric data they contain is translated appropriately when AbstractComponent's translateXYZ method is invoked.

  • Method Details

    • getDirection

      public Vector3D getDirection()
      Returns a vector pointing from the midpoint of this component towards the readout end of the component (e.g. towards the PMT of a scintillator).
      Returns:
      the direction of the readout end

    • getLine

      public Line3D getLine()
      Returns a line running down the middle of the length of the component such that the two end points of the line segment are at the geometric centers of the two polygons defining this component's volume. By convention, the origin point of the line lies at the geometric center of the first face and the end point of the line lies at the geometric center of the second face.

      Note that getLength()=getLine().length().

      Returns:
      a line running down the middle of the length the component

    • getVolumeIntersection

      public boolean getVolumeIntersection(Line3D line, Point3D inIntersect, Point3D outIntersect)
      Returns true if the given line segment intersect the volume-shape twice (one incoming intersection and one out going) and stores the incoming and outgoing intersection points are stored in the first and second Point3D objects given as arguments respectively.

      The incoming intersection is defined such that the incoming intersection point is closer to the origin of the line than the outgoing intersection point.

      Developer's Note: For optimization, this algorithm assumes that

      1. the volume contains N*4-4 triangular faces
      2. the faces form a closed bounding volume
      3. neither end point of the line segment are inside the volume
      4. pairs of faces from index 0 through N*2-1 (i.e. 1 and 2, 2 and 3, 3 and 4, etc.) are coplanar (the side trapezoids)
      5. the faces from N*2 through N*3-3 are coplanar (the first base)
      6. the faces from N*3-3 through N*4-5 are coplanar (the second base)
      where N is the number of points in either polygonal base.
      Parameters:
      line - the line segment
      inIntersect - the incoming intersection
      outIntersect - the outgoing intersection
      Returns:
      true if two intersections are found
