threestudio-3dgs

The Gaussian Splatting extension for threestudio. This extension is writen by Ruizhi Shao and Youtian Lin. To use it, please install threestudio first and then install this extension in threestudio custom directory.

Advanced Gaussian Splatting Installation (Recommend)

cd custom
git clone https://github.com/DSaurus/threestudio-3dgs.git
cd threestudio-3dgs
git clone --recursive https://github.com/ashawkey/diff-gaussian-rasterization
git clone https://github.com/DSaurus/simple-knn.git
pip install ./diff-gaussian-rasterization
pip install ./simple-knn

Native Gaussian Splatting Installation

cd custom
git clone https://github.com/DSaurus/threestudio-3dgs.git
cd threestudio-3dgs
git clone git@github.com:graphdeco-inria/gaussian-splatting.git --recursive
cd gaussian-splatting/submodules
python -m pip install diff-gaussian-rasterization/.
python -m pip install simple-knn/

# If you want to export mesh, please install pymeshlab
pip install pymeshlab

Quick Start

# Native Gaussian Splatting + SDS Loss
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting.yaml  --train --gpu 0 system.prompt_processor.prompt="a delicious hamburger"

# Advanced Gaussian Splatting with background + SDS Loss
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting_background.yaml  --train --gpu 0 system.prompt_processor.prompt="a delicious hamburger"

# Advanced Gaussian Splatting with background and shading + SDS Loss
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting_shading.yaml  --train --gpu 0 system.prompt_processor.prompt="a delicious hamburger"

Gaussian Splatting + MVDream

Please first install MVDream extension, then you can run the following script:

# Advanced Gaussian Splatting with background and shading + MVDream
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting_mvdream.yaml  --train --gpu 0 system.prompt_processor.prompt="an astronaut riding a horse"

Gaussian Splatting + Zero-123

# Advanced Gaussian Splatting + Zero-123
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting_zero123.yaml --train --gpu 0 data.image_path=./load/images/anya_front_rgba.png

Resume from checkpoints

# resume training from the last checkpoint, you may replace last.ckpt with any other checkpoints
python launch.py --config path/to/trial/dir/configs/parsed.yaml --train --gpu 0 resume=path/to/trial/dir/ckpts/last.ckpt

Load from PLY

# load from Gaussian Splatting ply file
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting.yaml  --train --gpu 0 system.prompt_processor.prompt="a delicious hamburger" system.geometry.geometry_conver_from=path/to/poinc_cloud.ply

# only load points position and color from ply file
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting.yaml  --train --gpu 0 system.prompt_processor.prompt="a delicious hamburger" system.geometry.geometry_conver_from=path/to/poinc_cloud.ply system.geometry.load_ply_only_vertex=true

If you want to use shap-e initialization, please install threestudio-shap-e extension first.

# load from shap-e initialization
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting.yaml  --train --gpu 0 system.prompt_processor.prompt="a delicious hamburger" system.geometry.geometry_convert_from="shap-e:a delicious hamburger"

If you want to use LRM initialization, please install threestudio-lrm extension first.

# load from lrm initialization
python launch.py --config custom/threestudio-3dgs/configs/gaussian_splatting.yaml  --train --gpu 0 system.prompt_processor.prompt="a delicious hamburger" system.geometry.geometry_convert_from="lrm:a delicious hamburger"

Export

You can use the following script to export Gaussian Splatting ply file and mesh obj.

python launch.py --config path/to/config --export --gpu 0 system.prompt_processor.prompt="a delicious hamburger" resume=path/to/last.ckpt
