torch-splatting

A pure pytorch implementation of 3D gaussian splatting.

Train

clone the repo

git clone https://github.com/hbb1/torch-splatting.git --recursive

install the env / libs

conda env create -f environment.yml
conda activate torch-splatting

and run

python train.py

Tile-based rendering is implemented. Because running loop for python is slow, it uses 64x64-sized tile instead of 16x16 as 3DGSS did. The training time is about 2 hours for 512x512 resolution image for 30k iterations, tested on a RTX 2080Ti. The number of 3D gaussians is fixed, of 16384 points. Under this setting, it matches the original diff-gaussian-splatting implementation (~39 PSNR on my synthetic data).

Stay Tuned.
