[ICCV 2025] DiffusionGS: Baking Gaussian Splatting into Diffusion Denoiser for Fast and Scalable Single-stage Image-to-3D Generation and Reconstruction

Data Description

These are the demo results of our ICCV 2025 paper.

HuggingFace Model Link

We also release our models in HuggingFace:

https://huggingface.co/CaiYuanhao/DiffusionGS

Here are some video generation results demo:

· (a) Object-level Generation

· (b) Mesh Exportation

· (c) Scene-level Generation

· (d) Comparison with Hunyuan3D-v2.5

The first row is the prompt image. The second row is Hunyuan3D-v2.5. The third row is our DiffusionGS.

Our method generates better results while enjoying 7.5x faster inference speed.
