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.

log_demo0.mp4

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 🚀

We will update a real-time rendering tool designed for immersive visualization.
