Progress in numbers

  • • .t3 load errors: 5155 → 0 (S29, 217 stub classes)
  • • Clean cold start: 284 log lines instead of 12986
  • • Meshes: generate → transform → Metal render with occlusion
  • • MIDI and audio (incl. 3D) verified on real hardware

Remaining work by priority

  • • GPU core stack: ResourceManager.Device, Texture2D/SRV, AbstractShader (~40+ files)
  • • Compute shaders: GL ≤ 4.1 can't — Metal path exists (MetalComputeRuntime)
  • • Video: VideoPlayback/VideoFrame FULL-guarded, Plan_MacVideo* written
  • • Audio input: WASAPI stub, native path deferred to Plan_MacCoreAudioNative.md

Effort estimates (AI-assisted)

  • • First GPU operator behind the ready provider: ~1–2 weeks
  • • MSL compute via MetalComputeRuntime: ~1–2 weeks
  • • Video playback/export (VideoToolbox or FFmpeg): ~3–6 weeks
  • • CoreAudio input per Plan_MacCoreAudioNative: ~1–2 weeks
  • • Full GPU core stack (42 files, HLSL→MSL): ~2–4 months incrementally

Not a mechanical port

  • • HLSL shaders of 272 GPU operators need a real MSL/GLSL backend
  • • Report estimate: full GPU port is months, not an abstraction exercise
  • • But seams are ready: ShaderCompiler.Instance, ITexturePresentationProvider
  • • Increments already proven AI-assisted: S36 GLSL demo, S66 Metal command path

Nothing to port

  • • 12 mesh modify operators are empty upstream too
  • • ExtrudeCurves and RepeatMeshAtPoints empty since 2023
  • • NDI/Spout are out of scope for the macOS port
