CydandClaude Fable 5 44aa7a349c BT410 5.3.38: SegmentArc270 never applied its 270 degrees
The class computed segmentSpan = 0.75 in its ctor and nothing ever read it:
the engine SegmentArc base has no span member, and SegmentArc270 declared no
Execute, so the recharge dial lit all 20 segments at PercentDone 1.0 where
the shipped cockpit lights 15 and leaves the quarter gap.  That was the last
MFD delta -- four extra spokes at the upper-left of every weapon disc.

A derived Execute is the only place the 0.75 can reach the draw, which is the
same role SegmentArcRatio's Execute plays with its own copy.  It scales the
raw fraction, draws, then restores: the connection only rewrites currentValue
when its source changes, so scaling in place would compound frame after frame
and walk the dial to zero.

Cockpit: 98.2% identical / 97% coverage.  The three MFD heads and the three
engineering heads are now within a few dozen pixels of the shipped binary.

Scene Restorations

Modern re-renderings of the Division dVS scenes recovered from the Glaze developer drive (see HISTORY.md) and this repo's CONTENT tree. The originals ran on Division Ltd.'s pixel-pipeline hardware in 19941997; these tools parse the original data files and re-render them in WebGL, in the browser.

Viewers (open in any browser, fully self-contained)

  • vwe-archive.html — the Scene Archive: 26 curated scenes across all projects — Star Trek (Enterprise-D, Klingon flyby), Hull Pressure (sea demos, fish schools, sunken temple), BattleTech (polar map with mech lineup, Ravine and desert maps, stadium), Red Planet (Blade arena, the Mars canal milestone demo), and the Canyon/Maya-temple Division demos. Fly camera: drag to look, WASD to fly, R resets.
  • trek-scn.html — the original standalone Star Trek restoration (TREK.SCN and KLNGVID.SCN).

Toolkit

  • divformats.py — parsers for every Division format found on the drive: text VGF/VMF (DIV-VIZ2 geometry/materials, both the 1995 VERSION 2:07 and 1996 02:05 dialects, with header SCALE support), binary BGF/BMF (DIV-BIZ2) — the binary block-stream layout was recovered from Division's own reader source (DPL3/BIZREAD.C, 1994), including all 14 vertex layouts, pmesh/tristrip/polygon connectivity, LOD blocks (newer writers nest patches inside LODs; the largest LOD is taken), and embedded materials/textures/ramps — plus TGA and raw SVT textures, SPL splines, and SCN scene scripts.
  • audit.py — scans every .SCN on the drive and reports what fraction of its geometry survives, and in which format.
  • extract_all.py — extracts every scene with ≥60 % of its geometry recoverable (108 of 241 on the drive; the rest reference lost models) into allscenes.json, resolving models/materials/textures across the drive and this repo's CONTENT dirs.
  • gallery_build.py — curates scenes from allscenes.json into the self-contained vwe-archive.html (via gallery_template.html).
  • convert.py / viewer_template.html — the original single-scene Star Trek pipeline.

Fidelity notes

Faithful: vertices, triangles, material colors and shading ramps, textures, fog and light parameters, spline motion, camera start positions. Approximated: Division's rasterizer behavior, point sizes, timing (originals ran at 30 Hz). Not simulated: event-driven SPECIALFX particles. A few dev scenes had camera start positions inside geometry; those get overridden or auto-framed cameras (see START_OVERRIDE in gallery_build.py). Scenes missing one or more models from the drive say so in their header.
