This is a **tiny** toolbox  for **accelerating** NeRF training & rendering using PyTorch CUDA extensions. Plug-and-play for most of the NeRFs!

## Installation

```
pip install nerfacc
```

## Examples: 

Note: Before running those example scripts, please check in the script which dataset it is needed, and download
the dataset first.
