  • Method Details

    • get

      org.djutils.draw.point.Point2d get(double fraction)
      Returns the point at the given fraction. The fraction may represent any parameter, such as t in a Bezier, s in a Clothoid, or simply the fraction of length.
      Parameters:
      fraction - double; fraction.
      Returns:
      double; point at the given fraction.

    • getDirection

      default double getDirection(double fraction)
      Returns the direction at the given fraction. The fraction may represent any parameter, such as t in a Bezier, s in a Clothoid, or simply the fraction of length. The default implementation performs a numerical approach by looking at the direction between the points at fraction, and a point 1e-6 away.
      Parameters:
      fraction - double; fraction.
      Returns:
      double; direction at the given fraction.
