HARMONY300

HARMONY300 is a benchmark of 300 indoor scenes for single-image 3D scene reconstruction. Each case pairs a real (or synthetic) reference photo of a room with a reconstructed 3D scene and a physically-lit render, produced by the SceneWeave pipeline.

Splits

difficulty	scenes	description
`easy`	100	synthetic rooms (3D-FRONT renders)
`medium`	100	real photos, single dominant layout
`complicated`	100	real photos, cluttered / multi-object layouts
total	300

Per-scene contents

Each \<difficulty\>/\<room_type\>_NN/ folder contains:

file	description
`input.*`	reference photo (the model input)
`render_blender.png`	physically-lit Blender/Cycles render of the reconstruction
`scene_full.glb`	reconstructed 3D scene (shell + furniture + decorations)
`camera_vggt.json`	camera intrinsics/extrinsics used for the render

Scenes are named \<room_type\>_NN (e.g. living_room_01, bedroom_12, kitchen_02) with a global per-type counter.

License & attribution

This dataset mixes sources with different terms. It is released under CC-BY-NC-4.0 (non-commercial, attribution) — the most restrictive of the constituent licenses (3D-FRONT) applied uniformly for safety.

source	scenes	terms
Pexels	196	Pexels License — free use, attribution not required
Unsplash	2	Unsplash License — free use, attribution not required
3D-FRONT	100	non-commercial research only; must cite 3D-FRONT
3D-FUTURE	2	synthetic renders (via SceneGen); non-commercial research only; must cite 3D-FUTURE

Per-scene source and URLs are listed in attribution.csv.
Input images remain under their original source licenses (Pexels / Unsplash / 3D-FRONT); this dataset redistributes them, it does not relicense them. The generated 3D assets and renders are provided for non-commercial research use.
The easy (3D-FRONT) split may not be used commercially and requires citation of the 3D-FRONT dataset.

Takedown

If you are a rights holder and want an image removed, please open an issue or contact the maintainer; the corresponding scene will be removed promptly.
