### Features
- **3D Mesh Generation**: Upload a satellite image → get a downloadable `.obj` mesh with in-browser 3D preview.
- **Video Rendering**: Select a satellite image and sky panorama → render a walkthrough video along a trajectory.
### Usage
Upload a satellite image or select one from the examples, then click "Generate".
The model weights are loaded automatically from HuggingFace.
### Input Requirements
The satellite image should be at **zoom level 20** (same as the [VIGOR](https://github.com/Jeff-Zilence/VIGOR) dataset), resized to **512×512** pixels. You can download satellite tiles at this zoom level from any map tile API (e.g. Google Maps, Bing Maps, Mapbox).
> **Note**: GPU hardware is recommended for reasonable inference speed.
