ProteusNeRF

Project page | Paper

This repository contains a pytorch implementation for the paper: ProteusNeRF: Fast Lightweight NeRF Editing using 3D-Aware Image Contexts. Our work present a fast and lightweight framework for interactive editing of NeRF assets via existing image manipulation tools or generative frameworks.

Tested on Ubuntu 20.04

Install environment:

conda create -n ProteusNeRF python=3.10
conda activate ProteusNeRF
conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia
pip install opencv-python matplotlib numpy tqdm kornia scikit-learn diffusers["torch"] transformers jupyter

Quick Start

1. Smaller appearance-only edits

open and run edit_LLFF_app.ipynb

2. Larger edits

open and run edit_LLFF_geo.ipynb

Train and edit model from scratch

1. Prepare Dataset

  • LLFF dataset download nerf_llff_data.zip unzip to ./Dataset folder

2. Train NeRF

  • Download DINO pretrained model to ./pre_trained_models
  • Prepare features data of dataset by command: python get_fea.py --scene [SCENE]
  • Train NeRF python train_LLFF.py --scene [SCENE];

3. Set trained weights as NeRF asset

Copy trained bestmodel.pth file in folder ./training_results to folder ./pre_trained_models rename trained file as [SCENE].pth

Note: [SCENE] is one of the folder name in the folder ./nerf_llff_data e.g. flower, horns etc.

Now you can try the above quick start

To do

  • Release Methods
  • Optimise Render processing

Editing speed: 10-70s (A100) -> 3-58s (4090)

Rendering speed: 0.6-1.5 fps (A100) -> 2-2.2 fps (4090)
