In recent times, the generation of 3D assets from text prompts has shown impressive results. Both 2D and 3D diffusion models can help generate decent 3D objects based on prompts. 3D diffusion models have good 3D consistency, but their quality and generalization are limited as trainable 3D data is expensive and hard to obtain. 2D diffusion models enjoy strong abilities of generalization and fine generation, but 3D consistency is hard to guarantee. This paper attempts to bridge the power from the two types of diffusion models via the recent explicit and efficient 3D Gaussian splatting representation. A fast 3D object generation framework, named as GaussianDreamer, is proposed, where the 3D diffusion model provides priors for initialization and the 2D diffusion model enriches the geometry and appearance. Operations of noisy point growing and color perturbation are introduced to enhance the initialized Gaussians. Our GaussianDreamer can generate a high-quality 3D instance or 3D avatar within 15 minutes on one GPU, much faster than previous methods, while the generated instances can be directly rendered in real time.

## 🦾 Updates

- 6/26/2024: We have released [GaussianDreamerPro](https://taoranyi.com/gaussiandreamerpro/) with highly enhanced quality which can be seamlessly integrated into animation/simulation pipelines🚀.

- 5/14/2024: We update the results of our method on [T³Bench](https://t3bench.com/), refer to [arxiv paper](https://arxiv.org/abs/2310.08529v3) for details.

- 3/8/2024: We also provide a [GaussianDreamer extension for threestudio](https://github.com/cxh0519/threestudio-gaussiandreamer). Thanks for the contribution of [Xinhua Cheng](https://github.com/cxh0519/).

- 2/27/2024: Accepted by CVPR 2024.

- 12/6/2023: Update [arxiv paper](https://arxiv.org/abs/2310.08529).

- 11/27/2023: Update colab and huggingface demo.

## 🚀 Get Started

**Installation**

Install [3D Gaussian Splatting](https://github.com/graphdeco-inria/gaussian-splatting) and [Shap-E](https://github.com/openai/shap-e#usage) as fellow:

```

pip install torch==2.0.1+cu117 torchvision==0.15.2+cu117 torchaudio==2.0.2 --index-url https://download.pytorch.org/whl/cu117

pip install ninja

pip install -r requirements.txt

git clone https://github.com/hustvl/GaussianDreamer.git 

cd GaussianDreamer

pip install ./gaussiansplatting/submodules/diff-gaussian-rasterization

pip install ./gaussiansplatting/submodules/simple-knn

git clone https://github.com/openai/shap-e.git

cd shap-e

pip install -e .

```

Download [finetuned Shap-E](https://huggingface.co/datasets/tiange/Cap3D/blob/main/misc/our_finetuned_models/shapE_finetuned_with_330kdata.pth) by Cap3D, and put it in `./load`

**Quickstart**

Text-to-3D Generation

```

python launch.py --config configs/gaussiandreamer-sd.yaml --train --gpu 0 system.prompt_processor.prompt="a fox"

# if you want to import the generated 3D assets into the Unity game engine.

python launch.py --config configs/gaussiandreamer-sd.yaml --train --gpu 0 system.prompt_processor.prompt="a fox" system.sh_degree=3 

```

Text-to-Avatar Generation

```

python launch.py --config configs/gaussiandreamer-sd.yaml --train --gpu 0 system.prompt_processor.prompt="Spiderman stands with open arms" system.load_type=1

# if you want to import the generated 3D assets into the Unity game engine.

python launch.py --config configs/gaussiandreamer-sd.yaml --train --gpu 0 system.prompt_processor.prompt="Spiderman stands with open arms" system.load_type=1 system.sh_degree=3 

```

**Application**

Import the generated 3D assets into the Unity game engine to become materials for games and designs with the help of [UnityGaussianSplatting](https://github.com/aras-p/UnityGaussianSplatting).
