# LingBot 3D

Turn a short video into a 3D scene with LingBot-Map.

- uses the upstream `lingbot_map` package directly
- downloads checkpoints from `robbyant/lingbot-map`
- runs the SDPA fallback path instead of FlashInfer
- caps inputs to short clips so the app fits a shared ZeroGPU workflow
- exports a browser-friendly `.glb` scene plus a zipped artifact bundle

## Current Limits

- short demos only
- default frame cap: 24 frames
- preview uses a static embedded `viser` scene, not the live local `viser` server
- the app uses the upstream default checkpoint `lingbot-map.pt`

## Local Sanity Check

If you want to import the app locally without downloading the checkpoint at startup:

```bash
LINGBOT_SPACE_SKIP_MODEL_LOAD=1 python app.py
```
