Install diff-gaussian-rasterization at: https://github.com/graphdeco-inria/diff-gaussian-rasterization

conda create -n physdreamer python
conda activate physdreamer

pip install -r requirements.txt

python setup.py install

Download the scenes and optimized velocity and material fields from: https://huggingface.co/datasets/YunjinZhang/PhysDreamer/tree/main

Put folders of these scenes to data/physics_dreamer/xxx, e.g. data/physics_dreamer/carnations

Put pretrained models to ./models.

See dataset_dir and model_list in inference/configs/carnation.py to match the path of dataset and pretrained models.

cd projects/inference
bash run.sh
