# K-Planes Nerfstudio integration

This repository provides code to integrate the [K-Planes model](https://sarafridov.github.io/K-Planes) into [nerfstudio](https://docs.nerf.studio/en/latest/index.html).

It provides an alternative way to use k-planes in addition to the [official repository](https://github.com/sarafridov/K-Planes), which allows access to nerfstudio's in-browser viewer and additional training capabilities.
Beware that some details about the training procedure differ from the official repository.


## Installation

1. [Install nerfstudio](https://docs.nerf.studio/en/latest/quickstart/installation.html). This is `pip install nerfstudio`, but there are a few dependencies (e.g. `torch`, `tinycudann`) which may require further steps, so make sure to check their installation guide!
2. Install the k-planes nerfstudio integration (this repository): `pip install kplanes-nerfstudio`

## Included Models

Two models are included here:
 - `kplanes` which is tuned for the Synthetic NeRF dataset (i.e. chair, drums, etc.)
 - `kplanes-dynamic` which is tuned to the [DNeRF dataset](https://www.albertpumarola.com/research/D-NeRF/index.html) (dynamic, monocular video).

:exclamation: PRs are welcome for configurations tuned to different datasets :exclamation:

You can run the static model by calling (remember to use the correct data directory!)
```
ns-train kplanes --data <data-folder>
```
and connect to the viewer using the link provided in the output of the training script.

## Roadmap

Expected future updates to this repository:

 - [ ] Including all datasets used in the K-Planes paper
 - [ ] Clarifying configuration of colliders (near-far)
 - [ ] Add benchmarks and configs for *linear* models
