# Baking Gaussian Splatting into Diffusion Denoiser for Fast and Scalable Single-stage Image-to-3D Generation and Reconstruction
This repository presents **DiffusionGS**, a novel single-stage 3D diffusion model for object generation and scene reconstruction from a single view, as described in the paper:
[**Baking Gaussian Splatting into Diffusion Denoiser for Fast and Scalable Single-stage Image-to-3D Generation and Reconstruction**](https://huggingface.co/papers/2411.14384)
DiffusionGS directly outputs 3D Gaussian point clouds at each timestep to enforce view consistency and allows the model to generate robustly given prompt views of any direction, beyond object-centric inputs. It boasts over 5x faster speed (~6s on an A100 GPU) compared to state-of-the-art methods.

## Visual Examples
## Quick Demo
For object-centric image-to-3D generation model, we provide a single-line script to use the code:
```shell
python run.py
```
This code will automatically download the model checkpoints and config files from [HuggingFace](). Or you can manually download it from [this link](https://huggingface.co/coast01/LVSM/tree/main) and set it to local dir.
For detailed instructions on installation, data preparation, evaluation, and training, please refer to the official [GitHub repository](https://github.com/caiyuanhao1998/Open-DiffusionGS).
