Method Detail

• value

  public double value(double x,
             double y,
             double z)
               throws OutOfRangeException

  Compute the value for the function.

  Specified by:

  value in interface TrivariateFunction

  Parameters:

  x - x-coordinate for which the function value should be computed.

  y - y-coordinate for which the function value should be computed.

  z - z-coordinate for which the function value should be computed.

  Returns:

  the value.

  Throws:

  OutOfRangeException - if any of the variables is outside its interpolation range.

• isValidPoint

  public boolean isValidPoint(double x,
                     double y,
                     double z)

  Indicates whether a point is within the interpolation range.

  Parameters:

  x - First coordinate.

  y - Second coordinate.

  z - Third coordinate.

  Returns:

  true if (x, y, z) is a valid point.
