# PARALLAX — assets and notices

This supplied original exhibition follows one architectural sculpture through ten spatial perspectives. Its 18 persistent fragments, camera-ray alignment, mirror captures, membrane refraction, lighting and reassembly are authored geometry and shaders. It is a digital artwork, not an archaeological object, optical measurement or scanned museum artifact.

## Images and model

Four generated production images remain byte-identical: [transparent hero](assets/hero-form.png), [ivory gallery](assets/gallery-ivory.png), [museum gallery](assets/gallery-museum.png) and [black-stone texture](assets/basalt.png). The gallery and social image is a capture of the actual reassembled runtime sculpture with interface labels hidden. Thirteen selected reference images are design targets, preserved in repository provenance; they are not runtime screenshots. Original generation prompts, IDs, dimensions and SHA-256 records remain in `provenance/parallax/assets/provenance.json`.

The [assembled GLB](models/impossible-form.glb) and [model record](models/impossible-form.json) retain the original delivery bytes. The glTF 2.0 binary embeds its texture and contains 18 structural meshes, 19 nodes and 804 triangles, with no external image or buffer URI. The website builds the same sculpture from source to animate its fragments; the GLB represents its portable static assembled state. Mirror, membrane and animated light behavior remain in the website source.

## Fonts and dependencies

The 22 transparent WebP files in `stills/` are captures of this exhibition's actual live renderer, made on 2026-10-25. They show nine chapter relationships plus the left/right Alignment views, each in landscape and portrait. They are not newly generated artwork or measured optical data. Repository `docs/parallax/STILL-CAPTURES.json` records source hashes, capture poses, dimensions, byte counts and image SHA-256 values. The fallback labels them as captured views; reflection, refraction and camera travel remain live-renderer capabilities.

- Three.js: [complete MIT notice](licenses/THREE-LICENSE.txt). The delivered r186 core, module and Reflector match the existing Collection `three` 0.186.1 byte-for-byte and are built from that root dependency.

Font binaries retain their source SHA-256 values. No application-wide open-source license is declared in the delivery; no MIT grant for the custom application or generated artwork is inferred from a dependency's license.

The original ZIP remains outside Git and deployment. Archive SHA-256: `72768646c6de27b10f99e7ef7de2233e3c6c7a157661aae491084147051937f0`; 46,316,092 bytes; 73 entries. Repository delivery/import records preserve source hashes, mappings and omitted standalone tooling. Original source links and prompt history remain in scoped provenance.

## Runtime image encoding (25 October 2026)

The runtime uses WebP derivatives of the four original PNGs linked above. All alpha and nontransparent RGB values are preserved exactly; only the transparent hero's hidden RGB values are normalized by encoding. Original PNG bytes remain intact. The repository's `provenance/parallax/lossless-webp.json` records source and derivative hashes and the comparison. These are encoding derivatives of the same generated artwork, not new images.
