Re: [Numpy-discussion] 2D Hamming window

Hi, Gary Ruben wrote:

import numpy as np import scipy.signal as ss

# window the heightmap heightmap *= bw2d

Thanks very much for your solution, this is exactly what I needed! If I'm not mistaken, though, you can achieve the same result with h = hamming(n) ham2d = sqrt(outer(h,h)) which is a bit more compact. Regards, Henrik
