What options are available for smoothing the generated surfaces?

You can control surface smoothing using the 'smoothing' parameter. It includes two sub-parameters: 'iterations', which sets the maximum number of smoothing iterations (default is 0), and 'relaxationFactor', which specifies the degree of smoothing in each iteration (a value between 0 and 1, with a default of 1).
