CodeNeRF: Disentangled Neural Radiance Fields for Object Categories

Date : 27th Feb, 2022

This contains the implementation of the paper CodeNeRF. Please refer to the project webpage for demos.

Install the environment

conda env create -f environment.yml
conda activate code_nerf

Catalog

  • Training
  • Optimizing with GT pose
  • Editing Shapes/Textures
  • Pose Optimizing

Download the data (ShapeNet-SRN)

For ShapeNet-SRN dataset, you can download it from https://drive.google.com/drive/folders/1PsT3uKwqHHD2bEEHkIXB99AlIjtmrEiR

Training

python train.py --gpu <gpu_id> --save_dir <save_dir> --jsonfiles <jsonfile.json> --iters_crop 1000000 --iters_all 1200000

JSON files contain hyper-parameters as well as data directory. 'iters_crop' and 'iters_all' are number of iterations for both cropped and whole images.

Optimizing

python optimize.py --gpu <gpu_id> --saved_dir <trained_dir>

The result will be stored in <trained_dir/test(_num)>, and each folder contains the progress of optimization, and the evaluation of test set. The final optimized results and the quantitative evaluations are stored in 'trained_dir/test(_num)/codes.pth'
