Why uniform sampling in disparity affects performance w.r.t. positional encoding #160

For the LLFF forward facing scenes, ndc is used. Issue-18 says that with disparity sampling, higher frequencies of positional encoding confuses NeRF. In that case, why not input inverse z as input to the positional encoder instead of z?
