# roomform patch-graph ConvFormer
Boundary models for [roomform](https://github.com/johnathanchiu/roomform):
point cloud indoor scans in, room boundaries (walls, floors, ceilings —
inferred through occlusion) out, as a patch graph over an 8 cm voxel
lattice: 3 surface node classes + 13 forward-edge connectivity
channels. See the repo's
[model docs](https://github.com/johnathanchiu/roomform/blob/main/roomform/model/README.md)
for the architecture.
## Checkpoints
| file | params | input | heads | notes |
|---|---|---|---|---|
| `patch-graph-joint-rgb-55m-offset-head-r2.pt` | 55M | RGB, 11ch | offsets + door/window openings | **default** |
| `patch-graph-400-offset-isolated-r1.pt` | 27M | grayscale, 9ch | offsets | lightweight |
Format: `{"model": state_dict, "epoch": int, "config": {...}}` — the
config dict loads directly via `roomform.model.config.ModelConfig`.
## Usage
Drop a checkpoint into `checkpoints/` in the repo (the pipeline
downloads the default automatically) and run:
uv run python -m roomform.pipe.e2e SCAN.ply

requires a separate license (see the repo's LICENSE-WEIGHTS and

Trained entirely on synthetic data generated by the roomform internal
data pipeline; no third-party dataset terms attach to the weights.
