# TranSpace — `playroom_drjohnson` data pack
Data for the released demo of:
> **TranSpace: Progressive Anchoring for Metric-Consistent Scene Synthesis**
> Hyeshim Kim, Taehei Kim\*, Jihun Shin\*, Hyeonjin Kim, Sung-Hee Lee — *\*equal contribution*
> KAIST · ACM Multimedia 2026 (MM '26)
> [doi:10.1145/3767308.3836316](https://doi.org/10.1145/3767308.3836316)
Code: https://github.com/codeshim/transpace
TranSpace synthesizes the transition geometry between two separately captured
indoor scenes. This pack contains everything the pipeline needs to reproduce that
for the Deep Blending `playroom` and `drjohnson` rooms: the two reconstructed
rooms, the inpainted keyframes, and every intermediate video. The demo replays
these, so no generative model or API key is required.
## Download
```bash
pip install huggingface_hub
# everything (~19 GB)
hf download codeshim/transpace-playroom-drjohnson --repo-type dataset \
--local-dir data/playroom_drjohnson
```
Place it at `data/playroom_drjohnson/` inside the code repository, then:
```bash
python main.py
```

```
Each room directory is self-contained: its COLMAP reconstruction (`images/`,
`sparse/`) and its trained SVRaster voxel model (`checkpoints/`) side by side.
Three connector variants are provided for the same room pair — `type0` (wing
wall), `type1` (pony wall), `type2` (internal window). Only the RIGHT connector
varies; LEFT is an internal window in every variant. A variant's source videos,
alignment info and padding model must be used together.
`trspace_source_type*/` holds the inputs that were generated offline:
| | |
|---|---|
| `<VIEW>_generated.png` | inpainted keyframe |
| `<VIEW>_depth_raw.npy` | its aligned metric depth |
| `<START>_<END>_iterNN.mp4` | per-iteration transition video |
| `<START>_<END>_iterNN_f2m.mp4` / `_m2b.mp4` | final-closing segment videos |

The keyframes were produced with Google Vertex AI Imagen 2 (since retired) and
the intermediate videos with DeeVid AI Video Generation V2.1.
