CydandClaude Fable 5 32023a918f BT410 5.3.48: watcher ladder complete; the engine names the next brick
With every authored watcher resolving, the pod run reaches the mission, draws
the FULL COCKPIT with the board booted and audio running, and exits GAME-RC=0
with no Fail.  It builds no 3-D scene, and the engine says why:

  Entity 1:1 class3035 couldn't figure out how to MakeEntityRenderables
  L4VIDEO.cpp couldn't load object sky.bgf  (then the whole arena)
  NULL instance

VideoRenderer::MakeEntityRenderables (VIDREND.CPP:231) is the BOTTOM of a
virtual chain -- its comment says so outright -- and BTL4VideoRenderer does
not override it, so every entity falls through, no scene graph is built, and
the geometry that would hang off it never loads.

CORRECTS an earlier note in the roadmap: I recorded the first full-rig run as
proving '.BGF loading was never a reconstruction problem, only a missing
bridge', because the complaint count was zero.  It was zero because the run
Failed at a watcher long before reaching geometry.  Now that it gets there,
the loads are attempted and fail -- for want of renderables, not the bridge.

Next brick is the real btl4vid body, shape pinned by the surviving sibling
header RPL4VID.HPP: override MakeEntityRenderables, plus ReadSKLFile /
RecurseSKLFile to walk the .SKL skeleton pages into a dpl_DCS hierarchy and
load the .BGF geometry per node.  Renderable content from the BT411 donor.

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.
