Lost Engine Directory

This archive does two things. It hosts archival restorations of the engines it rebuilds itself, and it acts as a directory for finding other lost or dormant rendering and game engine resources. When a project is actively maintained, the archive does not fork or re-host it; it points to the maintainer.

Restorations hosted here

Engines rebuilt in this repository, with a reproducible harness and a verified build.

Engine State Where
Argonaut BRender v1.3.2 portable pure-C render path complete (loads and renders real .dat models) BRender packet

Actively maintained: go to the maintainer

These were assessed and found to be living projects. The archive indexes them as lineage and interop references and does not attempt a revival. Use the upstream repository.

Lost or reference-only: leads worth pursuing

Genuinely lost, dormant, or source-restricted engines. Some are buildable revival candidates, others can only be dossiers. Confidence varies; entries are leads, not claims.

Buildable revival candidates (genuinely lost)

  • Crystal Space 3D (github.com/crystalspace/CS, LGPL, dead since ~2011).
  • RenderWare, via the aap/librw clean-room substrate (original Criterion/EA source is lost/restricted).
  • Aqsis and Pixie (RenderMan-compliant renderers, dormant mirrors).

Missing from the roster, worth adding

  • Cosmo3D (SGI).
  • N64 GBI / Fast3D microcode family.
  • Sega Saturn SGL / SBL.
  • Sony PS1 LIBGPU / LIBGTE / LIBGS (Psy-Q / Programmer's Tool).
  • trueSpace / Caligari (Octree Software renderer).
  • BMRT (Blue Moon Rendering Tools) and its Entropy / Gelato lineage.
  • RealSpace Engine (Origin Systems, Wing / Strike Commander).
  • Blade Runner Engine (Westwood Studios).
  • Mercenary / Damocles (Novagen, Paul Woakes).
  • MathEngine Karma.
  • TDI Explore (Thomson Digital Image).

Reference-only (dossier deliverables)

IRIS GL, OpenGL Performer core (SGI never released libpf/libpr), QuickDraw 3D (Apple source never released), Reality Lab (RenderMorphics), the RenderMan interface specification, Softimage/Alias pipeline history, the tri-Ace PS2 renderer (GDC 2005 slides only), Sony ProDG/EB for PS2, and studio-heritage lineages such as Psygnosis Liverpool and Team Ico.

Restricted material is indexed as rights-posture metadata only. This directory never links to redistribution of proprietary source, leaked SDKs, or assets.
