# Sat3DGen: Comprehensive Street-Level 3D Scene Generation from Single Satellite Image

Sat3DGen is a framework for generating street-level 3D scenes from a single satellite image. It uses a geometry-first methodology to bridge the extreme viewpoint gap between satellite and street views, achieving high geometric fidelity and photorealism.

## Sample Usage

To use this model, you will need the code from the [official repository](https://github.com/qianmingduowan/Sat3DGen).

```python
from source.generator import Sat3DGen

# Load the model
Sat3DGen._skip_backbone_weights = True
model = Sat3DGen.from_pretrained("qian43/Sat3DGen")
model = model.to("cuda:0").eval()

# Proceed with inference as described in the repository
```
