PINBUSTERS ORIGINAL BACKDROPS
Cosom Enterprises local asset collection

23 original model resources from all seven venues, with 73 companion texture
resources and complete source geometry. 20 models contain exterior scenery;
3 are explicitly labelled interior wall art from Hollywood and Sports Bar.
The collection includes clouds, stars, skies, night skylines, hotel photo
panoramas, palms, desert mountain cards, a moon/building source object and
the original decorative mural strips. No artwork was repainted or generated.

OPEN THE GALLERY

With Node.js installed, double-click Start-Backdrops.cmd. Keep its server
window open and visit http://127.0.0.1:8465/. Alternatively, run:
  node serve.mjs --open
The server binds only to 127.0.0.1. Press Ctrl+C in its window to stop it.
This folder can also be served within the Cosom local hub as /backdrops/.
The gallery uses locally included Three.js modules and needs an HTTP server.

Choose a venue and model, drag to rotate, scroll to zoom, or right-drag to
pan. Download GLB saves the full selected model. Each texture thumbnail
downloads its decoded PNG. Fit model resets the inspection camera.

ORIGINAL ASSETS AND PROVENANCE

models/       Byte-identical copies of the validated original-model GLBs.
geometry/     Complete original-coordinate geometry JSON exports.
textures/     Complete original decoded top-mip PNGs, grouped by source PUB.
original/     Exact raw model and texture resource bytes from the game PUBs.
previews/     Texture-rendered inspection thumbnails of these original models.
evidence/     Model classification contact sheet and its individual renders.
provenance/   Original placement records, texture metadata and file hashes.
catalog.json  Gallery items, companion texture paths, source offsets and hashes.
tools/        Collection and inspection-preview scripts.

The model and PNG files are unchanged copies of the extracted lane collection.
Every copy was checked against its original export hash. Source model and
texture resource byte slices were checked against their recorded SHA-256.
Texture metadata and the precise item/resource counts are in catalog.json.
All 23 models were loaded in the browser with their textures and download
links. Venue filtering, rotation and wireframe were checked. The browser
reported no console errors or warnings. Original-placement records preserve
all 30 stored placements associated with these selected source models.

The 3D model previews are static geometry. All source parts remain together:
for example, Malaysia's moon and skyscraper share a single source object;
Vegas stores both upright and vertically reflected hotel photo panoramas.
The reflected panorama was not corrected or removed. Hollywood's neon strips
and Sports Bar's bowling-ball strip are interior murals, not exterior views.

GLBs use the existing X-reflected right-handed glTF conversion and original
baked vertex colors through unlit materials. The geometry JSON and placement
records retain the source coordinate system. Source visibility/LOD flags are
metadata; this gallery does not execute the game's visibility logic. Basic
glTF materials and top-mip textures do not reproduce the Wii's complete
shader, particle, reflection or lighting behavior. No game animation, physics
or runtime object spawning is supplied.
