# DirectLStudio Demo Scenes
This public dataset contains three trained 3D Gaussian Splatting scenes in the
runtime-ready SOG format used by
[DirectLStudio](https://github.com/CoronaEngine/DirectLStudio). It contains
inference assets only: no source photographs, training images, camera training
sets, checkpoints, optimizer state, or training code are included.
## Files

The machine-readable counterpart is [`manifest.json`](manifest.json). The
mixed per-file terms are authoritative in [`LICENSES.md`](LICENSES.md); the
repository-level `license: other` metadata intentionally does not flatten them
into a single license.
## Download
Install the Hugging Face CLI, then download one scene:
```powershell
hf download Royalvice/DirectLStudio-Demo-Scenes `
--repo-type dataset `
--include "scenes/lego/*" `
--local-dir .\DirectLStudio-Demo-Scenes
```
DirectLStudio also provides a hash-pinned helper:
```powershell
python .\tools\download_assets.py --scene lego --output .\assets\scenes
python .\tools\download_assets.py --scene garden --output .\assets\scenes
python .\tools\download_assets.py --scene bicycle --output .\assets\scenes
```
## Provenance
- **Lego** derives from the NeRF Synthetic Lego scene published with
[NeRF](https://www.matthewtancik.com/nerf). A trained 3DGS representation was
converted to SOG for DirectLStudio inference. The source asset attribution
and non-commercial restriction remain in force after training and format
conversion.
- **Garden** and **Bicycle** derive from the
[Mip-NeRF 360](https://jonbarron.info/mipnerf360/) dataset. Their trained 3DGS
representations were converted to SOG for DirectLStudio inference.
These runtime files are provided for renderer evaluation and demonstration.
They do not transfer rights beyond the terms listed in `LICENSES.md`.
