Hi Irina,
it's an iterative approximation to isotropic Gaussian smoothing (2 means two steps of iterative averaging).
I think the relationship is:
sigma = sqrt(niter * 2 / pi)
cheers, Bruce

Hi,
I was wondering what exactly it means to smooth a surface with a step of 2 (i.e., what filter and parameters are used).
Thanks, Irina
