Level of Gaussians
LoG utilizes a single RTX 4090 for training highly realistic urban-scale models and for their real-time rendering. Visit our project page for more demos.

Our code is built upon PyTorch and leverages gaussian-splatting techniques.
Quick Start
For a smooth setup, follow the installation guide.
Dataset Preparation
We employ Colmap to prepare the dataset. Refer to the preprocessing documentation for detailed instructions. A minimal example dataset is provided here.
Training
Training the model is as simple as one command:
python3 apps/train.py --cfg config/example/test/train.yml split train
We automatically configure heuristic parameters based on the dataset size.
We provide a path for interpolation visualization
python3 apps/train.py --cfg config/example/test/train.yml split demo_interpolate ckptname output/example/test/level_of_gaussian/model_init.pth
The visualization video will be stored at output/example/test/level_of_gaussian/demo_interpolate/rgb.mp4
Immersive Visualization :rocket:
We will update a real-time rendering tool designed for immersive visualization.
