SCS Studio v4.2 — the complete app (photo → 3D → room → BIM → procurement)

SCS Studio v4.2 — the complete app: photo → 3D → room → BIM → procurement

The current, full release. One furniture photo becomes a repaired, IFC-classified 3D object; a CP-SAT solver furnishes rooms and whole IFC buildings under German ASR workplace law; the result exports back to Revit — and since v4, the app can even find the cheapest real product to buy for any object it generated. Everything below is included in this download.

🚀 Install (2 clicks)

1. Download SCS_Studio_App_v4.2_lite.zip below (~510 MB), unzip anywhere.
2. Double-click SCS_Studio.bat — it checks Node/Python, self-installs packages on first run, starts the server and opens http://localhost:3000.

The lite bundle ships without the 4.7 GB ABO furniture library; rebuild it once with python backend/python-scripts/download_abo_subset.py (public Amazon dataset, CC-BY-4.0) — or extract a provided ABO_furniture_catalog.zip into the app folder.

Everything included (v1 → v4.2)

v1 — the full pipeline

• Photo → 3D: drag one furniture photo → TripoSR builds a mesh locally; Fast mode matches from the catalog. Chair-base grafts repair what AI can't reconstruct; every object auto-registers with a professional code (desk-TSG-042) and renumbers on delete.
• Build a room: 38-category catalog (ABO + generated + CC0 + your own uploads) placed by a people-aware CP-SAT solver — legroom, door swings, circulation, honest per-item refusals. 2D plan editor synced live with 3D. Exports CSV / GLB / IFC4.
• Building: drop ANY .ifc → automatic floor dissection → per-room smart suggestions → one-click populate at Light/Medium/Dense. Floor-by-floor 3D/2D navigation, X-ray mode, whole-building GLB + BIM IFC export.
• Research hub: the 5-AI benchmark (TripoSR, TripoSG, TRELLIS, SAM 3D, InstantMesh — 187 photos, F-scores vs ground truth, TripoSG 0.393 best), repair pipeline, catalog provenance, test reports.

v2 — editing, safety, human logic (v2.0 → v2.1)

• 90° yaw rotation of any selected piece (R / ⟳ / Ctrl+right-click) — 2D+3D synced, baked into exports; delete-everywhere; lock/unlock.
• German ASR compliance, cited: §5(3) staffing caps, movement areas, route widths by room type, protected access strips for fire extinguisher & first-aid — even at Dense.
• Human placement rules: presentation rows face the screen at viewing distance, ceiling projectors aimed at screens, armchair rows, rectangular-table edge seating (max 4/side, spares wall-parked), bins at arm's reach, planters in corners, microwave ON the counter.
• Capacity-guarded suggestions (never over the ASR limit), dependency realism, kitchen logic.
• DIN 277 room intelligence (v2.1): 1,506 fleet rooms auto-classified in DE/EN/NL/FR; 6 support room types (storage, wardrobe, entry, balcony, print, IT).
• Windows launcher SCS_Studio.bat, boot-verified bundles.

v3 — room-tab parity + presentation tooling

• Room 2D editor gains Delete (removes from 3D + IFC + all exports) and lock/unlock; collision checker with 0.90 m walking paths live-verified.
• 18 selectable room types with an annotated gallery (2D clearance zones + ASR criteria panels + 3D x-rays) and a print-ready A4 PDF.
• Presentation handoff pack, 35-slide deck generator, ROI analysis (measured: one room 59% time saved, a 6-storey office 95.3%, the 15-building fleet 95.9%).

v4 — procurement + the business case (v4.0 → v4.2)

• 🛒 Procurement: pick any generated item — or drop any IFC/GLB — and the app sweeps multiple companies (IKEA Deutschland, OTTO, POCO live keyless; eBay.de + Google Shopping via free API keys), CLIP-scores every product photo against your object, and reports the cheapest visually-similar product landed at your address (VAT, parcel vs Spedition, pickup alternative) in three business tiers, single + bulk, with a downloadable finance Excel pack.
• v4.2 sub-type awareness: the item's photos AND its mesh proportions decide what it really is — a baroque armchair searches "Sessel", a four-poster bed "Himmelbett", a Tolix stool "Barhocker" — and tiers are drawn only from the top-similarity band. Live study: bar stools matched at 0.90–0.92 similarity incl. a Tolix clone at 38.85 € landed.
• Honesty built in: every report prints the companies scanned and claims only "cheapest among the companies scanned". Limitations, the three-version findings (v1→v3 of look-alike matching) and a further-development roadmap are documented in-app.
• ROI page with downloadable Excel/CSV for the finance department.

✅ Test evidence

End-to-end 8/8 (incl. live photo→3D each run) · floor dissection 15/15 vs IFC ground truth · 7-storey drop test 81/81 rooms · ergonomics gate 40/40 ×2 · exact-geometry meter over ~6,000 placed pieces: zero real overlaps · release bundle boot-verified from clean extraction.

SCS Studio v2 — the full app (photo -> 3D -> room -> BIM)

SCS Studio v2 — the full application. One photo in -> a furnished, German-standard-compliant BIM building out. This release is cumulative: everything from v1.0.0 plus every v2 addition.

Install (Windows)

1. Download SCS_Studio_App_v2.0_lite.zip below, unzip — one SCS_Studio folder.
2. Install Node.js 18+ and Python 3.11+ (Add to PATH).
3. In the folder: npm install · pip install -r requirements.txt · python backend/python-scripts/download_abo_subset.py (one-time 4.7 GB ABO furniture catalog from Amazon's public dataset — the app runs before it too, with the generated catalog) · npm start
4. Open http://localhost:3000 in Chrome (graphics acceleration ON for 3D).

The full feature set (v1 foundation)

• Generate object: furniture photo -> segmented -> 3D mesh (TripoSR locally; TripoSG/TRELLIS/SAM 3D/InstantMesh benchmarked on cloud GPUs) -> repair packs + chair-base grafts -> real Neufert dimensions -> professional code (desk-SAM3D-001), auto-catalogued. Declared object types, in-app engine installs (VRAM-gated).
• Build a room: 38-category catalog (700+ coded items: ABO CC-BY, PolyHaven CC0, OURS), room types with cited ASR rule packs, Light/Medium/Dense, ✨ capacity-guarded suggestions, CP-SAT solver with honest refusals, 2D plan editor, CSV/GLB/IFC export.
• Building: drop ANY IFC (drop-tested: fresh 7-storey tower -> 9/9 floors, 81/81 rooms exact) -> per-room smart suggestions, picks + blueprints (right-click), populate with the full human rulebook (chairs face tables, projector ceiling-aimed at its screen, bins beside desks, coat racks at door flanks, corner planters, walking-path protection) -> save GLB / export BIM IFC.
• Research hub: the project as guided steps — benchmarks over 187 photos, 5-model gallery, Item Logic Register (rules vs the German standard), X-Ray Fleet, Fleet Report (~6,000 pieces, ~2,200 machine-checked connections), Live Layout Visualizer, Showroom, dated roadmap, test reports.

New in v2

• Rotate any placed piece 90° (R key / ⟳ button): Building 3D + 2D in sync, yaw-only — pieces face the four walls, never ceiling/floor — legality checked per turn, baked into GLB/IFC exports.
• Safety access (ASR): extinguisher (1.00 m) + first-aid (1.35 m) own a protected 0.90 m strip — unblockable at any density. Display panels get the same treatment (whiteboard/screen/mirror + 0.75 m visibility strip).
• Human seating: armchairs in rows (2 same direction; 4 as opposed pairs + side table with its plant); rectangular tables seat max 4 per long side centred + ends, spare chairs park at walls facing the room; petal rings only for round/square tables; meeting seats ring the table facing it.
• Kitchens (fridge + microwave ON the counter), dependency realism (no orphan bins/partitions), suggestions that always fit the room.
• 44 screened catalog variants for the 15 late categories — every category selectable; strict identical-item screening.
• Research hub step 1: "Code files and what they do" — every button, right-click and shortcut mapped to the exact code; tab deep-links (/#room, /#building).
