Splatwizard: Gaussian Splatting Compression Toolkit

Splatwizard is a one-stop toolkit designed for researching 3DGS compression, dedicated to accelerating community exploration in this field. With flexible API design, you can easily combine advanced components from state-of-the-art models to build customized models. Key features of the project include:

• Easy-to-adapt evaluation framework for new models
• Comprehensive evaluation metrics
• Multiple baseline models included for comparison

Installation

Splatwizard can be installed via pip

pip install splatwizard

Since the installation process requires significant time to precompile all components, you can monitor the installation progress using the --verbose option.

pip install splatwizard --verbose

Additionally, pip compiles components in an isolated environment by default. You can use --no-build-isolation to perform the compilation directly in the current environment. Make sure torch and ninja are installed before running the command.

pip install splatwizard --verbose --no-build-isolation

To speed up compilation, the installation process uses all available CPU cores by default. If you need to limit the number of cores used for compilation, you can specify the maximum cores used via environment variable MAX_BUILD_JOBS. The following command will use up to 8 CPU cores during compilation.

MAX_BUILD_JOBS=8 pip install splatwizard --verbose --no-build-isolation

Quick start

Train your first 3DGS model in splatwizard

sw-train \
    --source_path /data/MipNeRF-360/bicycle \
    --output_dir /output/gs \                  
    --model 3dgs \
    --optim 3dgs

Evaluate model

sw-eval \
    --source_path /data/MipNeRF-360/bicycle \
    --output_dir /output/gs \                  
    --model 3dgs \
    --optim 3dgs \
    --checkpoint /output/gs/checkpoints/ckpt30000.pth
