Injector

[oneup03]

Summary

Adds 3DVision4All as a proxy-DLL injector that hooks DirectX 9 and NvAPI Stereo
in-process, capturing each eye's frame and compositing the stereo output the
display needs — no external Shader Glass window required. Also rewrites the
docs site so the injector is the default workflow for every output mode and
demotes the Shader Glass setup to a collapsible legacy section.

What's new

Injector (src/, proxy/)

• Four interchangeable proxy DLLs (dinput8.dll, dsound.dll, version.dll,
  winmm.dll) share a single DllMain and forward exports to the real
  system DLL. dsound.dll additionally /EXPORTs Direct3DCreate9{,Ex} so
  HelixMod fixes that route D3D through DSOUND chain correctly.
• D3D9 / D3D9Ex vtable hooks + NvAPI Stereo hooks drive a two-pass per-eye
  capture (src/Hooks_DX9.cpp).
• Output paths:
  • Overlay compositor (src/Output_Overlay.cpp, src/Compose_D3D11.cpp)
    handles sbs, tab, row_interlaced, column_interlaced, and
    checkerboard via a shared D3D11 compose pipeline.
  • LeiaSR (src/Output_LeiaSR.cpp) hands an SbS-packed texture to the
    Simulated Reality weaver for Acer Spatial Labs / Samsung Odyssey 3D.
  • Katanga (src/Output_Katanga.cpp) publishes frames over the Katanga
    IPC protocol for Katanga.exe / VRScreenCap to display in an HMD.
• Capture modes: CPU readback (default, widest compat) and GPU-shared
  (alternate_capture_mode = 1, faster but some games glitch).
• Diagnostic switches for bisecting init crashes (install_device_hooks,
  install_d3d9_vtable_hooks, install_d3d9_display_mode_hooks).
• Config via 3dvision4all.ini next to the game EXE with inline comments on
  every option (mode, swap_eyes, force_windowed, defeat_directflip,
  disable_vsync, confine_cursor, hide_cursor, render_width/height,
  copy_width/height, log_file/log_level).

Build

• 3DVision4All.sln + per-proxy .vcxproj files; static-linked CRT.
• _build_win32_release.bat / _build_x64_release.bat and a VSCode task.
• GitHub Actions workflow (.github/workflows/build.yml) producing
  Win32-Release/ and x64-Release/ artifacts.
• Submodules: Deviare2 (hooking), SR-lib (LeiaSR), nvapi.

Docs rewrite

• New shared includes: _includes/Injector.md (3DFM → NV CP Discover mode →
  fix install + verify in anaglyph at 1080p → proxy DLL + ini drop → full
  options reference) and _includes/InjectorPlay.md (running a game).
• Per-output guides now lead with the injector and tuck Shader Glass /
  3D Game Bridge / HelixVision-Katanga / Virtual Desktop into
  <details> collapsibles:
  • docs/SbSTaB.md — mode = sbs / tab
  • docs/ARGlasses.md — mode = sbs with Full-SbS render override guidance
  • docs/SRDisplay.md — mode = leiasr (no ReShade / 3D Game Bridge needed)
  • docs/HMD.md — mode = katanga with VRScreenCap shortcut params; both
    HelixVision/Katanga and Virtual Desktop methods preserved as collapsibles
  • docs/Interlaced.md — keeps EDID ID Override as the default (native
    3DVision interlaced); injector method added as a collapsible alternative
• docs/Native.md is unchanged (the injector doesn't apply to native
  frame-sequential / frame-packed / anaglyph paths).
• README.md video guide labeled as outdated (Shader Glass-era).
