CydandClaude Fable 5 740ef2b0a7 BT410 Phase 5.3.32: the per-head A/B -- three engineering heads now exact
The gauge framebuffer is PLANE-PACKED: L4GAUGE.CFG gives each port a bit
mask, not a rectangle, so all six heads share the same x/y and are separated
only by bit -- the packing the VDB splits into the pod's physical screens.
Comparing RGB was therefore measuring nothing useful; the "magenta artifact"
just meant the wrong heads were lit at that pixel.

New instruments (emulator/render-bridge/gauge-ab/, with a README):
  planes.py  per-head scoreboard -- shipped vs ours, missing vs extra, per
             port mask, recovering the 16-bit word from DOSBox's RGB565
  BT_VIS_LOG a complete cockpit widget map from the single dispatch every
             gauge widget is built through (MethodDescription::Execute),
             printing name + port + authored position
  ab.sh      stages the fresh build over BTL4REC.EXE and kills any running
             DOSBox before launching -- see below

The fix: the Comm page's pilot roster is the POD roster (the viewpoint mech's
ControlsMapper pilot array, mapper attributes 15/16), not the mission's
player list.  It is zero in a solo mission, so the shipped page draws empty;
ours resolved the local player and painted its icon in colour 0xff.  The gate
belongs in the row source, not PilotList::Execute -- Execute's empty branch
still has to run, because erasing is what the shipped page draws.

  head    shipped    ours   missing   extra          (was)
  Eng1      17981   17981         0       0     (0 / 1030)
  Eng2      17981   17981         0       0
  Eng3      17981   17981         0       0
  Comm      15656   13557      2099       0     (2099 / 1253)
  Heat      21374   20913       566     105     (566 / 990)

Title-band magenta 404 -> 0.  The 2099 Comm pixels we are missing were
missing before the gate, so it is a strict improvement.

Method note, which cost more than the bug: the rig's confs run BTL4REC.EXE
out of the mount while the build writes build410/btl4opt.exe, and nothing
connected the two.  Three measurements ran an hour-old binary, so a change
that "did nothing" three times had never been tested -- and the correct first
hypothesis was discarded on that evidence.  ab.sh now re-stages every launch.

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.
