## **Abstract**

 <img src="./assets/teaser.png" height=450>

While 3D generative models have greatly improved artists' workflows, the existing diffusion models for 3D generation suffer from slow generation and poor generalization. To address this issue, we propose a two-stage approach named Hunyuan3D-1.0 including a lite version and a standard version, that both support text- and image-conditioned generation.

In the first stage, we employ a multi-view diffusion model that efficiently generates multi-view RGB in approximately 4 seconds. These multi-view images capture rich details of the 3D asset from different viewpoints, relaxing the tasks from single-view to multi-view reconstruction. In the second stage, we introduce a feed-forward reconstruction model that rapidly and faithfully reconstructs the 3D asset given the generated multi-view images in approximately 7 seconds. The reconstruction network learns to handle noises and in-consistency introduced by the multi-view diffusion and leverages the available information from the condition image to efficiently recover the 3D structure.

Our framework involves the text-to-image model, i.e., Hunyuan-DiT, making it a unified framework to support both text- and image-conditioned 3D generation. Our standard version has 3x more parameters than our lite and other existing model. Our Hunyuan3D-1.0 achieves an impressive balance between speed and quality, significantly reducing generation time while maintaining the quality and diversity of the produced assets.

## 📈 Comparisons

We have evaluated Hunyuan3D-1.0 with other open-source 3d-generation methods, our Hunyuan3D-1.0 received the highest user preference across 5 metrics. Details in the picture on the lower left.

The lite model takes around 10 seconds to produce a 3D mesh from a single image on an NVIDIA A100 GPU, while the standard model takes roughly 25 seconds. The plot laid out in the lower right demonstrates that Hunyuan3D-1.0 achieves an optimal balance between quality and efficiency.

## Get Started

#### Begin by cloning the repository:

```shell
git clone https://github.com/tencent/Hunyuan3D-1
cd Hunyuan3D-1
```

#### Installation Guide for Linux

We provide an env_install.sh script file for setting up environment.

python3.9 and CUDA11.7+ (recommended)
```
conda create -n hunyuan3d-1-py39 python=3.9
conda activate hunyuan3d-1-py39
pip install torch==2.2.0 torchvision==0.17.0 --index-url https://download.pytorch.org/whl/cu118
bash env_install.sh
```
or python3.11 and CUDA12.1+ see [link](https://github.com/Tencent/Hunyuan3D-1/issues/9#issuecomment-2458695670)
```
conda create -n hunyuan3d-1-py311 python=3.11
conda activate hunyuan3d-1-py311
pip install torch torchvision xformers --index-url https://download.pytorch.org/whl/cu121 
bash env_install.sh
```
#### Download Pretrained Models

The models are available at [https://huggingface.co/tencent/Hunyuan3D-1](https://huggingface.co/tencent/Hunyuan3D-1):

+ `Hunyuan3D-1/lite`, lite model for multi-view generation.
+ `Hunyuan3D-1/std`, standard model for multi-view generation.
+ `Hunyuan3D-1/svrm`, sparse-view reconstruction model.

To download the model, first install the huggingface-cli. (Detailed instructions are available [here](https://huggingface.co/docs/huggingface_hub/guides/cli).)

```shell
python3 -m pip install "huggingface_hub[cli]"
```

Then download the model using the following commands:

```shell
mkdir weights
huggingface-cli download tencent/Hunyuan3D-1 --local-dir ./weights

mkdir weights/hunyuanDiT
huggingface-cli download Tencent-Hunyuan/HunyuanDiT-v1.1-Diffusers-Distilled --local-dir ./weights/hunyuanDiT
```

#### Inference 
For text to 3d generation, we supports bilingual Chinese and English, you can use the following command to inference.
```python
python3 main.py \
    --text_prompt "a lovely rabbit" \
    --save_folder ./outputs/test/ \
    --max_faces_num 90000 \
    --do_texture_mapping \
    --do_render
```

For image to 3d generation, you can use the following command to inference.
```python
python3 main.py \
    --image_prompt "/path/to/your/image" \
    --save_folder ./outputs/test/ \
    --max_faces_num 90000 \
    --do_texture_mapping \
    --do_render
```
We list some more useful configurations for easy usage:

We have also prepared scripts with different configurations for reference
```bash
bash scripts/text_to_3d_demo.sh 
bash scripts/text_to_3d_fast_demo.sh 
bash scripts/image_to_3d_demo.sh 
bash scripts/image_to_3d_fast_demo.sh 
```

This example requires ~40GB VRAM to run.

#### Using Gradio

We have prepared two versions of multi-view generation, std and lite.

For better results, the std version of the running script is as follows
```shell
python3 app.py
```

For faster speed, you can use the lite version by adding the --use_lite parameter.

```shell
python3 app.py --use_lite
```

Then the demo can be accessed through http://0.0.0.0:8080. It should be noted that the 0.0.0.0 here needs to be X.X.X.X with your server IP.

## Camera Parameters

Output views are a fixed set of camera poses:

+ Azimuth (relative to input view): `+0, +60, +120, +180, +240, +300`.
