Method Detail

• getStart

  public Vertex getStart()

  Get start vertex.

  Returns:

  start vertex

• getEnd

  public Vertex getEnd()

  Get end vertex.

  Returns:

  end vertex

• getLength

  public double getLength()

  Get the length of the arc.

  Returns:

  length of the arc (can be greater than \( \pi \))

• getCircle

  public Circle getCircle()

  Get the circle supporting this edge.

  Returns:

  circle supporting this edge

• getPointAt

  public Vector3D getPointAt(double alpha)

  Get an intermediate point.

  The angle along the edge should normally be between 0 and getLength() in order to remain within edge limits. However, there are no checks on the value of the angle, so user can rebuild the full circle on which an edge is defined if they want.

  Parameters:

  alpha - angle along the edge, counted from getStart()

  Returns:

  an intermediate point
