Value range of shape displacement

[jacksoncsy]

Hello Anpei,

Thanks a lot for the great work, very impressive!
I am trying to generate the final detailed mesh from 'result.displacementmap.png' and 'result.obj'. I can see that your network predicts the shape displacement in the range of [-1,1], and you finally scale them into [0,255].
I wonder what is the correct scale factor if I want to apply this displacement to the proxy mesh? Obviously, none of the aforementioned ranges is valid.

Many thanks,
Shiyang
