Requirements

Note:

• To utilize multiresolution hash encoding or fully fused networks provided by tiny-cuda-nn, you should have least an RTX 2080Ti, see https://github.com/NVlabs/tiny-cuda-nn#requirements for more details.

Install

git clone --recursive git@github.com:dehezhang2/RISE-SDF.git

Environments

• Create python 3.10 environment

  conda create --name rise-sdf python=3.10
  conda activate rise-sdf

• Install PyTorch>=1.13 here based the package management tool you used and your cuda version (older PyTorch versions may work but have not been tested)

  conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.7 -c pytorch -c nvidia

• Install Nvdiffrast

  git clone https://github.com/NVlabs/nvdiffrast.git
  cd nvdiffrast
  pip install .

• Install tiny-cuda-nn PyTorch extension and other dependencies (make sure you are in the CUDA available mode):

  pip install --global-option="--no-networks" git+https://github.com/NVlabs/tiny-cuda-nn#subdirectory=bindings/torch
  pip install -r requirements.txt

  • if you find a problem with nerfacc, uninstall your current nerfacc and build it again.

      pip uninstall nerfacc
      pip install git+https://github.com/nerfstudio-project/nerfacc.git

Datasets & Preparation

• Download the pre-integrated BSDF into the ./load/bsdf/ folder.
• Download the environment maps from TensorIR Dataset into the ./load/ folder.
• Download the TensoIR Dataset, save the files to the ./load/TensoIR_synthetic/ folder (for TensoIR, you need to change the config file albedo_format = 'png', has_roughness=false).
• Download Shiny Inverse Rendering Dataset, save the files to the ./load/TensoIR_synthetic/ folder.

Physically Based Inverse Rendering (PBIR)

Training

Run the launch script with --train, specifying the config file, the GPU(s) to be used (GPU 0 will be used by default), and the scene name:

# on Shiny Inverse Rendering Dataset
python launch.py --config configs/split-mixed-occ-tensoir.yaml --gpu 0 --train dataset.scene=toaster_disney 

The config snapshots, checkpoints, and experiment outputs are saved to exp/[name]/[tag]@[timestamp]. You can change any configuration in the YAML file by specifying arguments without --, for example:

python launch.py --config configs/split-mixed-occ-tensoir.yaml --gpu 0 --train dataset.scene=toaster_disney tag=iter50k seed=0 trainer.max_steps=50000

Relighting

The training procedure is by default followed by testing, which computes metrics on test data, generates animations, and exports the geometry as triangular meshes. If you want to do testing alone, just resume the pre-trained model and replace --train with --test, for example:

python launch.py --config exp/split-mixed-occ-tensoir-toaster_disney/your_experiment_directory/config/parsed.yaml --resume exp/split-mixed-occ-tensoir-toaster_disney/your_experiment_directory/ckpt/epoch\=0-step\=40000.ckpt --gpu 0 --test models.phys_kick_in_step=0

Note that you can change the relighting environment map easily in the config file

dataset
  relight_list:  ['bridge', 'city']
  hdr_filepath: ./load/high_res_envmaps_2k/
