Erik cffc3ee343 feat(render): portal-based EnvCell visibility (Step 4) 
Port ACME's EnvCellManager portal visibility system:

- New CellVisibility class: BFS portal traversal from camera cell,
  portal-side clip-plane test, FindCameraCell with grace period
- LoadedCell data populated during streaming (portals, clip planes,
  world/inverse transforms, local AABB from CellStruct vertices)
- WorldEntity.ParentCellId tags interior entities for filtering
- InstancedMeshRenderer.Draw accepts optional visibleCellIds set —
  interior entities whose parent cell isn't visible are skipped
- Conditional depth clear between terrain and static mesh when
  camera is inside a cell (ACME GameScene.cs pattern)

When camera is outdoors, all interiors render (visibleCellIds=null).
When camera enters a building, only BFS-reachable cells render.

acdream

Experimental modern open-source Asheron's Call client in C# / .NET 10.

Status: pre-alpha, not playable. Phase 0 only — dat file asset inventory.

Stack: .NET 10, Chorizite.DatReaderWriter for dat parsing. Silk.NET + Avalonia planned for rendering/UI (not yet wired up).

Requires: A retail Asheron's Call install (Turbine/Microsoft property — supply your own). Set ACDREAM_DAT_DIR environment variable to the directory containing client_portal.dat, client_cell_1.dat, client_highres.dat, and client_local_English.dat, or pass it as the first CLI argument.

Layout

  • src/AcDream.Cli/ — console app that dumps asset counts from a dat directory
  • references/ — local read-only reference material (ACE, ACViewer, WorldBuilder, DatReaderWriter, holtburger, retail AC install). Gitignored.

Run

dotnet run --project src/AcDream.Cli -- "C:\path\to\Asheron's Call"

Or set ACDREAM_DAT_DIR and run without args.
