Зміни FORM: об’єднання геометрії, спрощення, стиснення, текстури WebP, адаптація матеріалів, освітлення та власний переглядач. Це не авторські моделі FORM і не перевірені інженерні копії.

## Service illustration layer
Engine block/cover, intake, brake disc, caliper/pads, strut, spring and battery are original procedural illustrations created for this project. They reuse a shared library with per-vehicle visual anchors. They are not OEM CAD, not verified exact internal geometry, and do not establish part compatibility. No third-party product photographs are embedded in this layer. Source implementation: Tools/gltf-pipeline/service-layer.js; shared catalogue: service-parts.js.


## Engine study sources and changes / 2026-11-01

- Four-cylinder inline piston engine cutaway — Innerscene, CC0. https://www.innerscene.com/tools/library/3d-parts/four-cylinder-inline-piston-engine-cutaway-e0417b1b . Original GLB and STEP retained. FORM: component rig, materials, UVs, original microtextures, cam profiles/followers, PFI rail/injectors/spark-plug illustration, lighting, camera and service interaction. This is generic teaching geometry, not an OEM engineering specification.
- Disassembled V8 Engine_ANIM — antoniosalvatoreolia, CC BY 4.0. https://sketchfab.com/3d-models/disassembled-v8-engine-anim-7b61484920384338ba318f02bb330de5 . FORM: lossless geometry cleanup, viewer, lighting, material response and component selection. Source animation tracks retained; not a verified complete engine simulation.
- V6 Car Engine with engine morethem — Blendoriano, CC BY 4.0. https://sketchfab.com/3d-models/v6-car-engine-with-engine-morethem-7309cf5e6b07435c962f954513ca170e . Downloaded 4K GLB retained for evaluation only, not yet integrated. Author describes a game asset with simplifications; it is not evidence of a modern PFI/GDI engine layout.

## Current FORM no-name presentation / 2026-11-01

- Passenger-car exterior adapted from **Audi A7 Sportback 2018**, **KiW (QlER5)**, **CC BY 4.0**: https://sketchfab.com/3d-models/audi-a7-sportback-2018-95700e5a98904b3591c6a03a4b67787b . Acquired as the licensed redistribution at https://github.com/pedrosoandre/carros/blob/main/assets/audi-a7.glb . This is a previously reduced redistribution, not the full original 687,712-face download. Official source API licensing evidence is retained under Originals/a7/source-metadata.json. FORM changes: removal of emblems and original wheels, original split-spoke wheels, materials, orientation, compression and a separate mobile variant.
- SUV exterior adapted from **Range Rover Sport 2018**, **diw3d**, **CC BY 4.0**: https://sketchfab.com/3d-models/range-rover-sport-2018-d1fe581b3baf4af89275e9aa9a1392e2 . FORM changes: removal of visible names, grille/wheel badges, paint/carbon treatment, orientation and two geometry tiers.
- **FORM bearing sculpture**, split-spoke wheels, shared brake/suspension/battery illustration and lighting: original procedural work in mechanical-signature.js, atelier-wheels.js, chassis-mechanism.js and service-vehicle-viewer.js.
- Engine internals use the Innerscene CC0 teaching CAD described above, plus FORM rig and PFI visualization. These shared assemblies are not verified fits inside the adapted car exteriors.
- Static illustrations and hero posters are rendered screenshots of these same licensed/original assets. Attribution applies equally to the static views.

The client-facing category names do not claim a manufacturer affiliation. These exteriors remain derivatives of their credited sources, not entirely original vehicle designs.

## FORM precision gears — original editorial artwork
Procedural geometry, materials and lighting created for this project in Tools/gltf-pipeline/precision-gears.js. No third-party mesh or texture is used. The public homepage uses the pre-rendered assets/illustrations/precision-gears.webp; it does not load the render tool. Decorative illustration, not a validated manufacturing drawing or OEM part. The previous bearing composition is no longer displayed beside the vehicles.
