Question about the position input of the MLP x.

[GostInShell]

Hi! Thanks for open sourcing the code of your wonderful work!

I have some questions about the position input x of the NeRF MLP.
If I get it right, x is in NDC space. While the same point in the world space may have different 'x' in the NDC space, as the output view changes. So could you share some insights on the effect of x here? Thanks a lot!
