caiyuanhao1998/Open-DiffusionGS

Integrates Gaussian Splatting directly into the diffusion denoising process to enable single-image 3D reconstruction in ~6 seconds without requiring separate multi-view diffusion or depth estimators. Supports both object-level generation from single views with mesh export and scene-level reconstruction, trained on Objaverse and RealEstate10K datasets using diffusion-gaussian-rasterization and simple-knn backends. Achieves 7.5× speedup over comparable methods while maintaining quality across diverse inputs from synthetic objects to in-the-wild photographs.
