positional encoding

[Torment123]

Hi, thanks for the great work and congrats for CVPR acceptance. I saw in the code that ob_dist and ob_view are directly concatenated with anchor feature and input to the MLPs. Would using positional encoding (like in NeRF) further improve the view-dependent appearance rendering? as it captures high frequency variations, thanks.

Thanks. We choose direct concatenation because 1) reducing the total computation; 2) we find that a naive PE does not always contribute to a better results. Further explorations are welcome.
