Script: Convert a Normal Map to a Height (Displacement) Map

Dependencies: Python3, Numpy, Scipy

Usage:

python N2H.py [Number of iterations] [NormalMapFile] [MaskFile (optional)]

• Number of iterations: An integer, increasing the precision of generated height map, while requiring more execution time.

• NormalMapFile: A PNG or JPG image

• MaskFile: A PNG or JPG image, optional. If not provided, the script generates a mask based on the alpha channel of the normal map.
