# HunyuanWorld-1.0 Demo Space

This is a Gradio demo for [Tencent-Hunyuan/HunyuanWorld-1.0](https://github.com/Tencent-Hunyuan/HunyuanWorld-1.0), a one-stop solution for text-driven 3D scene generation.

## How to Use

1.  **Panorama Generation**: 
    - **Text-to-Panorama**: Enter a text prompt and generate a 360° panorama image.
    - **Image-to-Panorama**: Upload an image and provide a prompt to extend it into a panorama.
2.  **Scene Generation**:
    - After generating a panorama, click "Send to Scene Generation".
    - Provide labels for foreground objects to be separated into layers.
    - Click "Generate 3D Scene" to create a 3D mesh from the panorama.

## Technical Details

This space combines two core functionalities of the HunyuanWorld-1.0 model:

- **Panorama Generation**: Creates immersive 360° images from text or existing images.
- **3D Scene Reconstruction**: Decomposes a panorama into layers and reconstructs a 3D mesh.

This demo is running on an NVIDIA T4 GPU. Due to the size of the models, the initial startup may take a few minutes.

### Code Usage
For Image to World generation, you can use the following code:
```python
# First, generate a Panorama image with  An Image.
python3 demo_panogen.py --prompt "" --image_path examples/case2/input.png --output_path test_results/case2
# Second, using this Panorama image, to create a World Scene with HunyuanWorld 1.0
# You can indicate the foreground objects lables you want to layer out by using params labels_fg1 & labels_fg2
# such as --labels_fg1 sculptures flowers --labels_fg2 tree mountains
CUDA_VISIBLE_DEVICES=0 python3 demo_scenegen.py --image_path test_results/case2/panorama.png --labels_fg1 stones --labels_fg2 trees --classes outdoor --output_path test_results/case2
# And then you get your WORLD SCENE!!
```

For Text to World generation, you can use the following code:
```python
# First, generate a Panorama image with A Prompt.
python3 demo_panogen.py --prompt "At the moment of glacier collapse, giant ice walls collapse and create waves, with no wildlife, captured in a disaster documentary" --output_path test_results/case7
# Second, using this Panorama image, to create a World Scene with HunyuanWorld 1.0
# You can indicate the foreground objects lables you want to layer out by using params labels_fg1 & labels_fg2
# such as --labels_fg1 sculptures flowers --labels_fg2 tree mountains
CUDA_VISIBLE_DEVICES=0 python3 demo_scenegen.py --image_path test_results/case7/panorama.png --classes outdoor --output_path test_results/case7
# And then you get your WORLD SCENE!!
```

### Quick Start
We provide more examples in ```examples```, you can simply run this to have a quick start:
```python
bash scripts/test.sh
```

###  3D World Viewer

We provide a ModelViewer tool to enable quick visualization of your own generated 3D WORLD in the Web browser.

Just open ```modelviewer.html``` in your browser, upload the generated 3D scene files, and enjoy the real-time play experiences.
