• IHO Video
• DTU (NeuS Preprocess Link | Raw Link)
• BlendedMVS (NeuS Preprocess Link | Raw Link)
• OmniObject3D

• set ${DATASET} as one in [iho, dtu, bmvs, omniobject3d]
• set ${OBJECT_NAME} as the name of the object in the dataset

python train.py -g 0 --config configs/Color_NeuS_${DATASET}.yaml -obj ${OBJECT_NAME} --exp_id ${EXP_ID}

• -g, --gpu_id, visible GPUs for training, e.g. -g 0. Only supports single GPU.
• --exp_id specify the name of experiment, e.g. --exp_id ${EXP_ID}. When --exp_id is provided, the code requires that no uncommitted change is remained in the git repo. Otherwise, it defaults to 'default' for training and 'eval_{cfg}_{OBJECT_NAME}' for evaluation. All results will be saved in exp/${EXP_ID}*{timestamp}.

# IHO Video: ghost_bear
python train.py -g 0 --config configs/Color_NeuS_iho.yaml -obj ghost_bear --exp_id Color_NeuS_iho_ghost_bear
# DTU: dtu_scan83
python train.py -g 0 --config configs/Color_NeuS_dtu.yaml -obj 83 --exp_id Color_NeuS_dtu_83
# BlendedMVS: bmvs_bear
python train.py -g 0 --config configs/Color_NeuS_bmvs.yaml -obj bear --exp_id Color_NeuS_bmvs_bear
# OmniObject3D: doll_002
python train.py -g 0 --config configs/Color_NeuS_omniobject3d.yaml -obj doll_002 --exp_id Color_NeuS_omniobject3d_doll_002

All the training checkpoints are saved at exp/${EXP_ID}_{timestamp}/checkpoints/

We also provide our implementation of NeuS in this repo. To train NeuS, you can replace Color_NeuS_${DATASET}.yaml with NeuS_${DATASET}.yaml in the above command line, such as:

# IHO Video: ghost_bear
python train.py -g 0 --config configs/NeuS_iho.yaml -obj ghost_bear --exp_id NeuS_iho_ghost_bear

• set corresponding ${DATASET} and ${OBJECT_NAME} as above
• set ${PATH_TO_CHECKPOINT} as the path to the checkpoint (.pth.tar) to be loaded

python evaluation.py -g 0 --config configs/Color_NeuS_${DATASET}.yaml -obj ${OBJECT_NAME} -rr 512 --reload ${PATH_TO_CHECKPOINT}

• -rr, --recon_res is the resolution of the reconstructed mesh. The default value is 512.
