NeRFPlayer: A Streamable Dynamic Scene Representation with Decomposed Neural Radiance Fields

This is an nerfstudio framework based implementation for NeRFPlayer.

Installation

NeRFPlayer follows the integration guidelines described here for custom methods within nerfstudio.

0. Install Nerfstudio dependencies

Follow these instructions up to and including "tinycudann" to install dependencies and create an environment

1. Clone this repo

git clone https://github.com/lsongx/nerfplayer-nerfstudio.git

2. Install this repo as a python package

Using NeRFPlayer

Now that NeRFPlayer is installed you can play with it.

Preparing data

• Currently only DyCheck dataset is supported.
• Download DyCheck data.
• You can capture your own scenes by following DyCheck's guide.

Run

• Launch training with ns-train nerfplayer-ngp --data <data_folder>. This specifies a data folder to use.
  • example: ns-train nerfplayer-ngp --data dycheck/mochi-high-five/
• Connect to the viewer by forwarding the viewer port, and click the link to viewer.nerf.studio provided in the output of the train script

Misc

Issues

Please open Github issues (under this repo, not under nerfstudio) for any installation/usage problems you run into.

Known TODOs

• Multi-camera datasets: DyNeRF, ImmersiveVideo
• Decomposition in NeRFPlayer. Under nerfstudio's framework, we got NaN soon if a decomposition module is used.
