PHOTO 1998 · RECTIFIEDRAKING LIGHT 2026

In 1998 the container’s skin was a skin landscape of close-ups of the body: pores, folds, a mirrored face on the front, a torso on the roof, a dark oval between the locking bars of the rear doors.

For Version E this skin was recovered from the photographs of the container: each surface is rectified through its four corners (homography) – front and long side from wab-018, roof and opposite side from the top view wab-008, the rear doors from wab-020. The arrangement follows the 1998 unwrapping; there the two long sides are mirror images, so the opposite side is mirrored. The brightness of the photographed skin yields the relief map with which the light reads the skin anew.

Drag the slider: left the rectified 1998 photograph, right the same skin in raking light.

Five surfaces, one net: roof in the middle, walls at the edges. Dragging the slider folds the skin into the container – which can be placed on a table in AR.

On the motorway every street lamp becomes a raking light. The skin of the long side, a light source passing by.

The keyword archive PATHBODY now holds 17,111 artefacts in 20,644 locations. New: every 3D format – GLB, glTF, OBJ, FBX, USDZ – with a working preview, dimensions, animations and its own AR page with QR code at exact scale; images undistorted with full screen and zoom; all videos in AI MW, the META–FIKTION films and the source code of the versions.

Skin

Perspective rectification of the container surfaces from the 1998 photographs (OpenCV, homography through four corners, Lanczos), greyscale with light balancing, relief map from photo brightness (high-pass, Sobel) – no collage, no AI image generation.

Image

Own image engine (Python · NumPy · Numba · OpenCV): raking light as Lambert shading of the relief map with a wandering cone of light, projected striped light, scan line as transition; 3D scenes with own rasterisation, the skin lit per frame in surface space. 3840 × 2160 · 25 fps · H.264 High 5.1.

Sound

Synthesised numerically: projector and scanner, skin noise, drone in fifths, steel when folding, truck and passing cars; inside the original 2025 sound. −16 LUFS.

3D · AR

glTF 2.0 from own Python writer: original skin as colour and normal map, folding net with hinges, doors, projection, raking light (KHR_lights_punctual), film camera · Blender exports (glTF, OBJ with textures, FBX with rig) · USDZ for iOS Quick Look · model-viewer with WebXR and Scene Viewer.

Archive

Indexer v10: additionally all 3D formats with web GLB, poster, dimensions, animations, USDZ and QR code per model; large image previews (1400 px) for the full-screen view; source code in full text; desktop app as a slim shell with its own protocol (pba://), packaged without symlinks.

Version E follows on from A to D – the same container (720 × 265 × 250 cm), the same archives – but returns to the skin itself: no longer the body as a plan, but the surface as it was, and the light that makes it legible.
